For instance, the vast majority of 7mm Rem Mag factory loads shoot bullets in the 139-175 grain range. 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. By running slightly less than max loads I've had cases go 18 times. 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. Just like with trajectory though, it’s a small edge due entirely to the slightly faster muzzle velocity of the Winchester Short Magnum cartridge. 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. More on this in a minute, but it’s worth noting that for those two AccuBond loads in particular, the 325 WSM has almost 95% of the kinetic energy of the .338 Win Mag and has essentially the same trajectory out to 200 yards. Not surprisingly, this results in some interesting ballistic comparisons. The table below compares the recoil produced by two Nosler hand loads (available here and here) with ballistics roughly comparable to the 140gr loads above for those cartridges when fired from a Winchester Model 70 Featherweight rifle. Inside of 200 yards no advantage. This is very likely the single most commonly used bullet size in North America, so there’s an excellent bullet selection for both cartridges. After all, a longer cartridge simply requires more space to feed and eject than a shorter cartridge. You got to figure one or two should survive. 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. With a 200-yard zero, the older .270 Win. Both are also capable of outstanding accuracy in the right hands. 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. The same goes for guns: rifles chambered in .270 Winchester are among the most commonly produced centerfire rifles in the United States. Proponents of the WSM cartridges also argue that this results in a shorter and wider powder column that’s more quickly ignited by the primer and burns more evenly than a comparable amount of powder in a longer and more narrow column. With the proper barrel and scope it has excellent longer range potential. 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. What about accuracy of the 270 Winchester vs 270 WSM? The exact size of the rifle action (which includes the locking bolt, firing pin, etc.) The Hornady .300 Win Mag shoots a little bit flatter due to its faster muzzle velocity, but the difference between them is so small that it’s probably not even worth considering. Unfortunately, the future isn’t looking very bright for that cartridge right now. So, while the rifle chambered in 300 WSM is not significantly lighter, it’s a tiny bit shorter and handier. I went with the 325 to try something different for a change. Maybe, but probably not. 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. They’re both solid performing cartridges, but I’d personally choose the 7mm Remington Magnum over the 7mm Winchester Short Magnum. I joined a deer lease this year and I'm hunting on a pipeline. The table below compares the recoil produced by two Nosler hand loads (available here and here) that essentially duplicate the AccuBond loads described above. That small reduction in recoil is also particularly helpful here as well. You can even use them both on larger game like kudu, eland, red stag, elk, and moose with great results. that. Sep 12, 2010 #6 2010 Ontario F Class Champion used a 270WSM necked up to 7mm. At 500 yards the .270 Win. While virtually every big ammo manufacturer produces factory hunting ammo for the .338 Win Mag, only Nosler and Winchester Ammunition currently produce 325 WSM hunting ammo as part of their Trophy Grade, Expedition Big Game, Power Max Bonded, and Super X lines (loaded with the AccuBond, E-Tip, AccuBond CT, Bonded Rapid Expansion Hollow Point, and Power-Point bullet respectively), For those reasons, most sporting goods stores usually carry ammunition for the .338 Win Mag, but 325 WSM ammo can be significantly harder to find. Like I said, they’re all well designed and very capable hunting cartridges. But for decades only one other commercial .270 hunting cartridge was released: the .270 Wby. Overall, the .338 AccuBond load is the best here with the 325 WSM AccuBond coming in a relatively close second. So, while the 7mm WSM is faster on paper, the two cartridges have essentially the same velocity for all intents and purposes. In terms of trajectory, the newer cartridge has an edge, but it’s relatively minor. Specifically, 180 grain, 200 grain, and 220 grain bullets are most popular for 325 WSM factory ammo. The 270 Winchester Short Magnum very likely does gain some accuracy benefit from its shorter powder column. Having said all that, when I recently compared the two, I ended up with the 7mmRM.
