|   For this reason, while they will do the job on deer sized game, the 325 WSM and .338 Win Mag are both excellent choices for larger game like caribou, elk, moose, red stag, kudu, and eland. Remember: we’re talking about accuracy under practical hunting conditions, not benchrest shooting where a tiny improvement in group size can make a big difference. Like its siblings, the .270 WSM has gained a steady following for a variety of reasons. The.270 WSM is a good cartridge but, honestly, it is a very small player in terms of market share. Maximum pressure obtained from SAAMI (p23, 24, 28, 30, 31, and 32). With a 200-yard zero, the older .270 Win. AFAICT, they fill the same niche and produce the same down-range results with the 140 grain bullets that I'm shooting from both of them. Now that we’ve covered the basic history and design of the Winchester Short Magnum cartridges, let’s see how they compare to the .270 Winchester, 7mm Remington Magnum, 300 Winchester Magnum, and .338 Winchester Magnum. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges.As you can see, the two cartridges have almost identical amounts of recoil with the 7mm Rem Mag in this particular example actually having a tiny bit less free recoil energy than the 7mm WSM. This is obviously not great news for fans of the 7mm Winchester Short Magnum and does not bode well for the future of the cartridge. That’s not to say that the .338 Win Mag won’t work for that sort of hunting because it certainly will. Getting a 7mm WSM ballistically does not get you any advantage over a regular 7mm Remington magnum. or even 300 Win. The .270,7mm and .300 WSM,s make the .30-06 look a little anemic.I don't understand why exactly but the .270 became fairly popular and the 7mm didn't catch on.I have two of them and they are decent.I had one reamed further in the freebore to use heavier bullets and keep base out of powder capacity.Of course the .270 doesn't have that problem because of limited choice in bullets. Perhaps the most surprising comparative result was that the 150 grain.270 WSM load carries more energy downrange than either of the 7mm Rem Mag loads. Both cartridges normally use bullets in 150-230 grain range. None of them have covered any new ground. It also spawned an entire family of cartridges. Finally, it’s also nice to have that extra round or two of ammunition in your magazine available if you end up needing it one day. However, even though the 7mm Mag is derived from the .375 H&H Magnum and itself uses a fatter case than cartridges like the .270 Winchester and .30-06 Springfield, the 7mm WSM still has a significantly fatter case with less taper and a steeper shoulder angle (35 degrees vs 25 degrees).Even though the 7mm WSM uses a larger diameter case, the 7mm Rem Mag uses a relatively large diameter case itself and is significantly longer. is not only a classic round. The 7mm WSM and 7mm Remington Magnum are best suited for the exact same hunting situations. The photo below does a great job of showing the differences in external dimensions between the 300 Winchester Magnum and the 300 Winchester Short Magnum. After all, fans of the Winchester Short Magnum cartridges like to point out the benefits of the shorter and fatter powder column. Mag. Mag. If you prefer a shorter, potentially lighter rifle, that’s slightly faster cycling and easier to carry, but still has magnum performance, then go with the 300 WSM. Both rifles in this case also have a 3 round magazine as well, so there’s no advantage there with either cartridge. Just like with the 270 WSM, this is due to the very large diameter of the 7mm WSM cases that simply take up more space in a rifle magazine than the thinner 7mm Rem Mag case. The recoil of some hard hitting cartridges. You can even use them both on larger game like kudu, eland, red stag, elk, and moose with great results. Make sure you subscribe to The Big Game Hunting Podcast and follow The Big Game Hunting Blog on Facebook, Instagram, Twitter, and YouTube. However, 200 grain, 225 grain, and 250 grain bullet weights are most common for .338 Win Mag factory ammo. I picked a bullet type and grain weight that was very similar and did a comparision on the Federal web site. ballistics. Absolutely. When you consider the fact that the 270 WSM has significantly more case capacity than the older .270 Winchester and that both cartridges have the same maximum SAAMI pressure, it shouldn’t be surprising that the 270 WSM is actually capable of shooting the same weight bullet at a higher velocity than the .270 Winchester. It also carries a tad more energy out to longer range and is capable of excellent accuracy. He loaded with Win brass, Fed 210M primers, H1000 and 180 gr Bergers. Maybe, but probably not. Both loads are compared when fired from a Winchester Model 70 Featherweight rifle. In today’s world, better to sugar coat it than to sound like we may be mocking. Additionally, the company also advertised that the shorter case used by the WSM cartridges resulted in superior accuracy and less recoil. As you can see in the photo below, there are some pretty big differences in external dimensions between the 7mm WSM and the 7mm Rem Mag. To put this into perspective, a Boeing 737 commercial airliner travels at … In that same vein, those fat, stubby 270 WSM cartridges with their very steep shoulder angle can sometimes present feeding problems. This specific model weighs 7.25 pounds when chambered in 270 WSM and 7 pounds when chambered in .270 Winchester. You got to figure one or two should survive. In the WSM .270 fans found a short, powerful, efficient round that could be housed in compact, lightweight short-action rifles and which edged closer to 7mm Rem. Is the 325 WSM capable of excellent accuracy? In fact, the difference in published velocity is often smaller for the 300 WSM vs 300 Win Mag than the 7mm WSM and 7mm Rem Mag. As you can see, the two Federal Premium loads used the exact same 180 grain bullets fired at the same velocity. Both loads are compared when fired from a Winchester Model 70 Featherweight rifle. Absolutely. For the majority of hunters, the .338 Winchester Magnum is the more practical choice. Is it significantly more accurate than the .338 Winchester Magnum? Even so, I’d personally lean towards .338 Win Mag since it generally functions more reliably, shoots larger diameter bullets, and is usually a tiny bit more powerful. But for decades only one other commercial .270 hunting cartridge was released: the .270 Wby. With that in mind, the 325 WSM is a better choice for situations where very large and tough game like sambar deer or moose are likely to be encountered at close range. They’re both great cartridges and I’d personally say that the 325 WSM is the second most appealing choice out of the Winchester Short Magnum line (behind the 300WSM). It’s not a gigantic difference, but this often means that the 270 WSM has a definite advantage in terms of external ballistics and sometimes slightly less recoil, but that the .270 Winchester is more often available in shorter, lighter, and easier to handle rifles. After all we wouldn’t want to hurt someone’s sensitive feelings. Just like with trajectory though, it’s a small edge due entirely to the slightly faster muzzle velocity of the Winchester Short Magnum cartridge. However, Winchester likely made an attempt at doing just that, but since the case is optimized for the 300 WSM, they probably were not getting the desired performance with a .338″ bullet and opted for a .323″ compromise instead. That said, while the 325 WSM is quite popular in some circles, it is not nearly as widely used and cannot hold a candle to the .338 Win Mag in that area. 325 WSM vs 338 Win Mag Ballistics Comparison for 270 Note: No company currently manufactures rifles chambered in 7mm WSM. That’s not a gigantic difference, but it’s certainly not nothing either. This results in less recoil. It is more available than the .270 Weatherby Magnum has ever been. The 270 WSM is one of the few calibers that actually has a ballistic advantage over the standard caliber of its own. Note: these are not the only broad categories of rifle actions. The data used to compare the trajectory and wind drift of the cartridges was obtained from Hornady (here, here, here and here), Federal (here, here, here, here, here, and here), Nosler (here), and Winchester (here). The .300 Winchester Magnum and 300 Winchester Short Magnum cartridges have essentially the same external ballistics. It’s a wonderful cartridge and there are plenty of quality ammo and rifle choices for you. While there is a big overlap in bullet weights the 325 WSM and .338 Win Mag can use (both cartridges are commonly loaded with bullets in the 180 grain to 250 grain range), the .338 Win Mag generally leans a little heavier than the 325 WSM. 270 vs 280 vs 280 AI vs 7mm Rem Mag Ammo Selection. It’s just that it doesn’t offer a significant improvement in power over the 325 WSM at close range, but still has more recoil. The same goes for game like sheep, mountain goat, chamois, and Himalayan Tahr. )Author Ron Spomer has shot most cartridges from 22 CB cap to 505 Gibbs and taken game with most of them. Most manufacturers produces rifles chambered in .338 Win Mag, so it’s not too difficult to find a good rifle in that cartridge. This is illustrated in the table below comparing Federal Premium and Hornady factory ammunition loaded with 180gr Trophy Bonded Tip (.500 BC) and 200gr Hornady ELD-X (.597 BC) bullets in .300 Winchester Magnum and 300 Winchester Short Magnum. However, their .555″ case diameter is larger than those used by the 7mm Rem Mag and .300 Win Mag (.513″) as well as the .270 Winchester (.470″). Just because it can be done does not mean it makes sense, despite what you might read in advertising copy. Though Winchester advertises a 24″ long barrel and a 7.25 pound overall weight for each cartridge in this particular Model 70, the rifle chambered in 325 WSM is 1/2″ shorter overall. For those reasons, the two cartridges have very similar case capacity, but the 7mm Rem Mag can hold a tiny bit more powder than the 7mm WSM. I was most always hunting Deer when the Elk showed up. Winchester Model 70 chambered in 7mm Remington Magnum & Remington Model 700 chambered in.270 Winchester. The .338 AccuBond load has a small, but definite advantage in wind drift at all ranges, but the 325 WSM has a bigger edge over the .338 Win Mag with the Winchester loads. As you can probably guess, there is very little difference in the trajectories in the two cartridges. After all, a longer cartridge simply requires more space to feed and eject than a shorter cartridge. Is it significantly more accurate than the .300 Winchester Magnum? The 7mm-08 case is just slightly longer than the parent .308—2.035 inches vs. 2.015 inches—but maintains the same 20-degree shoulder of the .308 Winchester. So, while the rifle chambered in 7mm WSM is not really any lighter, it’s a tiny bit shorter and handier. Like I mentioned a minute ago, that particular 325 WSM load above has essentially the same trajectory and still has about 95% of the kinetic energy of that .338 Win Mag load. However, the 8mm bullets (.323″) used by the 325 WSM (as well as the 8mm Mauser, 8mm Rem Mag, and 8×68 S) are not nearly as easy to find in the United States. Due to the long running popularity of the .270 Winchester, there’s a plethora of quality bullets to choose from for both cartridges. This is one of the tougher aspects of using the 325 WSM: there’s not a gigantic variety of factory ammo or a large number of bullet choices for hand loaders to choose from. By and large, the 270 WSM, 7mm WSM, 300 WSM, and 325 WSM are all capable of excellent accuracy and essentially duplicate the performance of comparable standard length cartridges while fitting in a short action. These are interesting cases where both lines of ammo use the same style bullet for both cartridges, but the Nosler ammunition uses a heavier bullet for the .338 Win Mag and Winchester uses a heavier bullet for the 325 WSM. Both cartridges also offer a substantial increase in power, both in terms of bullet frontal surface area and kinetic energy, over the 300 Magnums as well. Though I doubt that a well placed shot on an animal with an extra 200 feet per second of velocity or 250 foot pounds of energy will make a big difference, it won’t necessarily hurt either and I can see why someone would want that extra power, especially when hunting game like elk and moose. Both are wonderful for situations like hunting mule deer in Arizona or pronghorn in Wyoming. But, even though the .338 Winchester Magnum does have a belted case (which the 325 WSM lacks), the .338 Win Mag generally has a reputation for pretty reliable feeding in most rifles. Especially when hunting at shorter ranges (inside 200 yards), the 325 Winchester Short Magnum offers virtually the same performance as the .338 Win Mag, but with considerably less recoil. loads are typically a few cents cheaper per shot. The same goes for guns: rifles chambered in 7mm Remington Magnum are extremely popular and very commonly in the United States. While I would not describe the 7mm WSM as a rare or hard to find cartridge, it’s not especially popular or widely available. (All further WSM introductions will be based on this case as well.) Finally, while the two cartridges use the same 7mm bullets (.284″ diameter) and there is a big overlap in typical bullet weights for each cartridge, the 7mm WSM normally uses lighter bullets than the 7mm Remington Magnum. First, both have the same maximum SAAMI pressure of 65,000psi. bullet will retain 1,000 ft-lbs clear out at 830 yards. A bit more than the 7mm Rem. .222 Remington Rifle Cartridge – Family Portrait, Performance Center-Thompson/Center LRR Review, .17-Caliber Reloading Data and History for 5 Cartridges, Berger 30 Caliber 205 Grain Elite Hunter Bullet — New for 2020, .25-06 Rem. For all intents and purposes, there is no difference between them ballistically and both cartridges will really do a number on most species of big game. That’s not meant to be a knock on the Winchester Short Magnum line either. Mag. Tom Beckstrand and Neal Emery of Hornady highlight the 6MM Creedmoor ammo. With these loads, the bullet from the 7mm WSM is going 50-60 feet per second faster than the bullet from the 7mm Rem Mag. There is a decent selection of factory ammo available in the cartridge from companies like Federal, Hornady, and Winchester. Overall, the .338 AccuBond load is the best here with the 325 WSM AccuBond coming in a relatively close second. First, the .270 Winchester is significantly longer. However, the distance from the case head to the datum line on the shoulder is longer for the 7WSM, preventing accidental chambering or firing of the .284" 7mm bullet in .270 WSM's .277" bore. The .270 WSM is also capable of excellent accuracy but prefers slow-burning powders. With heavy (150 grain) bullets the difference is about 100 fps, hardly enough to place the WSM in a different league than the original .270 Win. The 325 WSM has similar ballistics to the magnum action, medium bore 8mm Remington Magnum and 8×68 S cartridges. rifles than WSMs on used gun racks. When comparing two loads with identical bullets (Hornady’s 145-grain Precision Hunter ELD-X), the .270 WSM is 130 fps faster than the .270 Win. Normally you’d be right and the rifle for the standard length cartridge would be either a little longer and heavier or virtually the same size and weight. Additionally, the .300 Win Mag has a shoulder moved further forward than the 7mm Rem Mag. It also carries a tad more energy out to longer range and is capable of excellent accuracy. drops about 3.5 inches more than the short mag at 500 yards. The 300 WSM and 325 WSM also have the benefit of doing all of the above with a modest decrease in recoil compared to the .300 Win Mag and .338 Win Mag while the 270 WSM offers a definite improvement in velocity over the .270 Winchester. Before we get started, I have an administrative note: Some of the links below are affiliate links. On paper, the Winchester Short Magnums are very closely matched with their standard length cousins. Just like with the 7mm WSM vs 7mm Rem Mag and 300 WSM vs 300 Win Mag, even though the 325 WSM uses a case with a larger diameter, the .338 Win Mag itself has a relatively large diameter case and is significantly longer. I joined a deer lease this year and I'm hunting on a pipeline. While both cartridges are really too light for hunting extremely large, thick skinned dangerous game like cape buffalo, they will both fit the bill for hunting Grizzly or Alaska Brown Bear. With the whims of the marketplace it may or may not stay readily available. The table below compares the recoil produced by two Nosler hand loads (available here and here) firing 200gr Nosler AccuBonds at virtually the same velocity: 2,885fps for the 300 WSM and 2,910 for the .300 Win Mag. So where do we stand with both cartridges? Plus, the .270 WSM could poach from an already extensive lineup of .277 … Not surprisingly, many sportsmen and women were a little skeptical about the line of Winchester Short Magnum cartridges introduced in the early 2000s that claimed to offer even better performance than these legendary centerfire rifle hunting cartridges. All told, both are wonderful cartridges for hunting some of the larger species of North American big game or African plains game. However, the .270 Win.’s long case body feeds easily in most rifles while the WSM has a reputation for being more finicky. Once again, there’s a good selection for both, but rifles chambered in 270 WSM aren’t quite as common and are usually more expensive. Great article, but I’ve always felt the 270 WSM should be compared to the 30-06. I’ve always thought the 270wsm was similar to the 7mm Mag. However, don’t underestimate the importance of the greater variety, wider availability, and lower overall cost of .270 Winchester rifles and ammunition. The 7mm WSM does indeed have a flatter trajectory and a tiny bit more resistance to wind drift than the 7mm Rem Mag. In that same vein, those fat, stubby 7mm WSM cartridges with their very steep shoulder angle can sometimes present feeding problems. Inside of 200 yards no advantage. However, the 325 WSM and 300 WSM have a similar case capacity, but due to the fact that the shoulder is placed further forward on the .300 Win Mag, the .338 Win Mag actually has a little less case capacity than the .300 Win Mag. lags behind the short mag by about 100 fps and the WSM carries about 150 ft.-lbs. If you already have a rifle in the cartridge and don’t mind the smaller selection of factory ammo (or if you’re into handloading), the 7mm WSM will also serve you very well as a hunting cartridge. Well, the 200gr 325 WSM bullet starts off with a little bit less muzzle energy than the 200 grain .338 Win Mag bullet, but the 325 WSM is more aerodynamic and pulls ahead in the energy and trajectory departments at 100 yards and 300 yards respectively. On the other hand, that’s not a gigantic advantage in favor of the 270 WSM either. This is not an ironclad rule though and it’s sometimes possible to find rifles chambered in .338 Winchester Magnum that can accommodate another round or two compared to those chambered in 325 WSM. Both cartridges are also well suited for hand loaders and reloading components for the .270 Winchester and 270 WSM are widely available. vs 6.5 Creedmoor — Cartridge Clash, Ruger Launches New American Rifle Predator in 6.5 Grendel, Mossberg Patriot Predator 6.5 PRC Rifle Review. RifleShooter Magazine editor Scott Rupp breaks down all the features of the Mossberg Patriot Predator rifle chambered in 6.5 PRC. That extra velocity makes a bit of a difference in terms of wind drift and overall trajectory to be sure, but that slightly flatter trajectory is less important in this day and age of laser rangefinders, particularly if you have a scope equipped with a bullet drop compensating dial. Both will work exceptionally well on deer sized game out to several hundred yards. Winchester Short Magnum History. At reasonable shooting ranges, there’s very little practical difference between them ballistically and both cartridges will really do a number on both species of game. The new .270 WSM and 7mm WSM are based on the original short, fat, beltless .300 WSM case, which was developed by Winchester and Browning sui generis for the new WSM series. For that reason, the .338 Winchester Magnum is probably the closest comparison to the .325 WSM that’s in common use in North America. 270 vs 308 WIN: WHICH ONE SHOULD YOU HUNT WITH? But at the opposite-and-equal-reaction end of that recoil is the bullet carrying 3,850 ft-lbs kinetic energy. This is an incredibly small practical difference. Does the difference between the two cartridges in terms of accuracy make a difference for most hunters under typical conditions? Like all the other Winchester Short Magnum cartridges, the 325 WSM is specifically designed to fit in a short action rifle instead of a standard length action like the larger .338 Winchester Magnum. 7mm WSM vs 7mm Rem Mag The 270 Winchester Short Magnum very likely does gain some accuracy benefit from its shorter powder column. With this load, the .270 WSM generates roughly 250 additional foot-pounds of energy over its competitor at the muzzle when both cartridges are fired from 24-inch barrels. Compare the 180 gr 30-06 verses the 150 gr 270 WSM and you get the same or possibly less recoil and better ballistics all around except energy with the 270 WSM. Though it’s possible to find rifles chambered in .300 Win Mag with a larger magazine, that’s a pretty typical magazine size for the cartridge. wusses when it comes to recoil. All are very solid performers that are extremely popular with big game hunters pursuing game like deer, elk, black bear, and moose. 270 WSM vs 270 Winchester Since the 270 WSM uses a significantly shorter cartridge, you’d probably expect rifles in that cartridge to be shorter and lighter than rifles chambered in .270 Winchester. The first three cartridges were all designed and marketed specifically as short action alternatives to extremely popular and effective standard length cartridges: the .270 Winchester for the .270 Winchester Short Magnum, the 7mm Remington Magnum for the 7mm Winchester Short Magnum, and the .300 Winchester Magnum for the 300 Winchester Short Magnum. On the other hand, the 300 WSM has a slightly higher maximum SAAMI pressure than the .300 Winchester Magnum (65,000psi vs 64,000psi). For those reasons, sporting goods stores usually carry ammunition for both cartridges. At the same time, the 300 WSM is the most popular Winchester Short Magnum cartridge and is also extremely commonly used as well. On the other hand, the majority of 7mm WSM factory loads use bullets in the 140-162 grain range and 140, 150, and 162gr bullets are pretty common. The release of the .270 Winchester in 1925 in the Winchester Model 54 rifle saw the beginning of the American love affair with velocity, as well as the laying of a solid foundation for the American bolt-action sporting rifle.At the time, the lever gun held court in the hunting fields, though through the writings of Mr. O’Connor, change was on the wind. This shouldn’t be surprising though because the 300 WSM is specifically designed to fit in a short action rifle instead of a standard length action like the larger .300 Winchester Magnum. There are a number of relatively inexpensive factory loads for the .270 Win. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges.This is the first instance where we’ve seen the Winchester Short Magnum serve up similar performance with an appreciable reduction in recoil. With bullets of 130 to 140 grains, the .270 WSM will buy you between 150 and 200 additional feet per second of velocity. Looking at this Nosler reloading page for the 270 WSM, it shows you can push 150 grain accubond long range bullets with a BC if 625 at 3150 fps. For those reasons, the .300 Win Mag actually has significantly more case capacity (around 10-15% more, depending on the manufacturer) than the 300 WSM. The two cartridges have a virtually identical trajectory out to 400 yards, but the less aerodynamic .338 bullet starts to drop off in performance at longer range compared to the 325 WSM. The answers to the above questions really depend on the rifle, ammunition, and shooter in question though. The last of these cartridges, the .325 WSM, was introduced in 2005. Violate this principle by, for example, chambering a lightweight, short action rifle for a powerful Magnum cartridge like the .300 WSM and the result will be a dramatic increase in kick. However, the 270 WSM has a very fat case with minimal taper and a much steeper shoulder angle (35 degrees vs 17.5 degrees).For those reasons, the 270 WSM is unique among the Winchester Short Magnum cartridges for actually having significantly more case capacity (around 10-20% more, depending on the case manufacturer) than its standard length cousin. Additionally, the .300 Winchester Magnum is a traditional belted magnum while the 300 WSM has a rebated rim and no belt.Just like with the 7mm WSM vs 7mm Rem Mag, even though the 300 WSM uses a case with a larger diameter, the .300 Win Mag also uses a relatively large diameter case itself and is significantly longer. Taken together, these factors all maximize the case capacity of the WSM cartridges, even though their overall length of 2.86″ is still short enough to fit in a short-action rifle. However, the Winchester Short Magnum cartridges all use a much fatter case without a belt that more closely resembles the case used by the old .404 Jeffery as well as the later Winchester Super Short Magnum (WSSM) line of cartridges. Both cartridges are also well suited for hand loaders and reloading components for the 7mm Remington Magnum and 7mm Winchester Short Magnum are widely available. Just put your shot were it needs to go. With that in mind, you’re probably not giving up any potential magazine space by choosing a rifle chambered in 300 WSM with a 3 round magazine. This means that it’s possible to build a short action rifle that’s a tiny bit shorter and lighter than an otherwise identical rifle with a standard length action. The .270 Win has a relatively flat trajectory itself, but the 270 WSM had a small, but definite advantage in this area. Both cartridges are also well suited for hand loaders and reloading components for the .300 Win Mag and 300 WSM are widely available. Not saying the .270 WSM is a 'wrong' choice, just not what I would chose if doing it again. Like I said, they’re all well designed and very capable hunting cartridges. This makes sense since the 7mm WSM is specifically designed to fit in a short action rifle instead of a standard length action like the 7mm Rem Mag. Or was the Winchester Short Magnum line of cartridges just a scheme by Winchester to sell new rifles that’s cleverly disguised by a bunch of marketing hype? For example, 4-5 round magazines are pretty common with the .270 Win, but 3 round magazines are about all you’ll find with the 270 WSM. The table below compares the recoil produced by two Nosler hand loads (available here and here) that essentially duplicate the AccuBond loads described above. Scroll down or click the appropriate link below to jump to the specific comparison you want to learn more about. The difference is not, however, extraordinarily dramatic. With the proper barrel and scope it has excellent longer range potential. Comments are turned off. But at 400 yards the difference is less than two inches. What about accuracy of the 325 WSM vs 338 Win Mag? However, regardless of the firearm in question, rifles chambered in .270 Winchester can usually hold an extra round or two in the magazine since that cartridge has a slimmer case. First, let’s talk about the history of the Winchester Short Magnum (WSM) line of cartridges and what the company was trying to achieve. On the other hand, the Winchester Short Magnum cartridge does not have a gigantic advantage in either category either and there’s actually a smaller difference in the ballistics of the 7mm WSM vs 7mm Rem Mag than there is with the 270 WSM vs 270 Winchester. The road to the famous Remington 700 rifle was paved with classics like the models 725 and 30s. The 325 WSM shoots .323″ bullets while the .338 Win Mag uses .338″ bullets. However, there are many, many other factors that influence accuracy more than that one trait. In terms of trajectory, the newer cartridge has an edge, but it’s relatively minor. Far Zero for the WSM load and the 140 grain 7mm load is identical, while FZ of the heavy WSM load is 10 yards longer than the 160 grain 7mm. So, while the rifle chambered in 300 WSM is not significantly lighter, it’s a tiny bit shorter and handier. That being said, it’s probably a little bit more expensive and, while there’s a good variety of ammo for the cartridge, the .270 Winchester usually has a bigger selection regardless of where you go.
