3.5 lbs. is i worth my time to get a 7mm wsm, i am looking at getting a browning X-bolt for hunting elk in either 7mm rem mag or 7mm wsm, the rem mag has 26 inch barrel and the wsm has 23 inch barrel would that make any difference, and i noticed that there is not as many factory loads for the wsm, but i have found a few that i know will work, and i plan on learning how to reload. Just put your shot were it needs to go. The 7mm Rem. These two cartridges present an interesting case though. The 325 WSM has similar ballistics to the magnum action, medium bore 8mm Remington Magnum and 8×68 S cartridges. The same goes for guns: rifles chambered in .270 Winchester are among the most commonly produced centerfire rifles in the United States. Stretch out to 400 yardsânot uncommon in mule deer countryâand the differences are beginning to add up, but the drop difference between the .270 Win. Before we get started, I have an administrative note: Some of the links below are affiliate links. 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, that particular 325 WSM load has about 83% of the free recoil energy of the .338 Win Mag load, which is a pretty major reduction in recoil. 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. Lightweight handy rifles giving magnum performance should have become more popular. This is not a hard and fast rule, but it is a common occurrence with these two particular cartridges. 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. 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. 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. 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. This is not always the case and some 270 WSM rifles feed exceptionally reliably of course, but it’s likely more of an issue with that cartridge that’s not often encountered with the 270 and its longer, slimmer, and more tapered case. While it’s certainly nice to have if possible, a the difference in a theoretical 1.25″ vs a 1.5″ group most likely won’t matter much while actually hunting at reasonable ranges. 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. what seems to be the most favourite of these 2 mags? With this in mind, designers at Winchester Repeating Arms elected to build a line of cartridges that could fit in a short length action with the goal of achieving similar performance to popular standard length cartridges. After all, fans of the Winchester Short Magnum cartridges like to point out the benefits of the shorter and fatter powder column. That heavier and more aerodynamic bullet retains energy better at long range and the edge in kinetic energy grows as the distance increases. For those reasons, sporting goods stores usually carry ammunition for both cartridges. I have both. The 325 WSM is an attractive choice for hunters in the niches I described above and those that use the cartridge generally seem to absolutely love it. 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. One thing to consider is the chance of hunting larger game . Is it significantly more accurate than the 7mm Remington Magnum? I can see the advantage of the short action, but you are asking which one is better in performance for long distance. Much more versatility if you ever need the bigger bullets. Interestingly enough, a .323″ bullet diameter is exactly halfway between the .308″ bullets used by the 300 WSM and .300 Win Mag on one hand, and the .338″ bullets used by the .338 Win Mag on the other. 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. Both are wonderful for situations like hunting mule deer in Arizona or pronghorn in Wyoming. The 7mm WSM does indeed have a flatter trajectory and a tiny bit more resistance to wind drift than the 7mm Rem Mag. Just like with trajectory though, it’s a small edge due entirely to the slightly faster muzzle velocity of the Winchester Short Magnum cartridge. Which is sort of an explanation of why I have the .300. CVA Paramount Muzzleloader: Read This Before You Buy One! Theyâre pretty much the same thing. 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. If you already have a quality rifle that you like chambered in either cartridge though, I don’t see any compelling reason to make a switch to the other one unless you just want to. Exactly why I went with 7mm. Let me know if you have any questions or requests. At the same time, the 300 WSM has most closely lived up to the hype, which explains why it’s far and away the most popular of the bunch. I went with the 325 to try something different for a change. The chart below compares how much a 10 mile per hour crosswind impacts those same four loads out to 500 yards. The 7mm WSM, 25 WSSM, and 223 WSSM are the guests of honor at a wake near you. In this article, Iâm going to do a detailed analysis of the 270, 7mm, 300, and 325 Winchester Short Magnum cartridges and compare them to the .270 Winchester, the 7mm Remington Magnum, the .300 Winchester Magnum, and the .338 Winchester Magnum in an effort to answer the above questions and parse out the their true strengths and weaknesses so you can make an informed decision regarding which one will work best for you. It’s a wonderful cartridge and there are plenty of quality ammo and rifle choices for you. 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. However, they’re being measured against four of the most popular American centerfire rifle cartridges of all time in the .270 Winchester, 7mm Remington Magnum, .300 Winchester Magnum, and .338 Winchester Magnum, and that’s a tough hurdle to get over. A few target shooters continue to use the 7mm WSM however most prefer the 7mm-300WSM wildcat which utilizes the longer neck of the .300 WSM case design. So, while the 7mm WSM is faster on paper, the two cartridges have essentially the same velocity for all intents and purposes. So, while the rifle chambered in 7mm WSM is not really any lighter, it’s a tiny bit shorter and handier. On the other hand, if a light weight rifle is less important and if you don’t have any issues with a standard length rifle action or just prefer an older and more established cartridge with a larger variety of ammo and rifle choices, then go with the .300 Win Mag. Looking at it that way, it’s not surprising that the 7mm WSM is likely on its way out. For those reasons, while the .338 Win Mag can generally hold a little more powder, the two cartridges actually have similar case capacities (depending on the manufacturer of course). By. As far as the discussion between the 300 short mag and the 7mm mag I think you are splitting hairs. First, the .270 Winchester is significantly longer. This is very likely the single most commonly used bullet size in North America, so thereâs an excellent bullet selection for both cartridges. 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. The exact size of the rifle action (which includes the locking bolt, firing pin, etc.) The 7mm Winchester Short Magnum very likely does gain some accuracy benefit from its shorter and fatter powder column. The Lyman 50th Edition (p197-198, 199-200, 214-216, 219-220,257-259, 260-262, 288-289, 294-295) and Hornady 10th Edition (p351-359, 356-359, 406-411, 412-416, 564-573, 574-585, 637-639, 659-664) reloading manuals were used as references for the history of the cartridges. 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? Does the difference between the two cartridges in terms of accuracy make a difference for most hunters under typical conditions? For all intents and purposes, we can say that the two cartridges have the same ballistics. Inside of 200 yards no advantage. That’s is because the 325 Winchester Short Magnum load in question uses about 12% less powder than the .338 Win Mag. 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. Re: 7mm mag vs 7mm wsm ?? 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. ballistics. Absolutely. The answers to the above questions really depend on the rifle, ammunition, and shooter in question though. more than the 160 grain 7mm load. However, the biggest shortcoming of all four Winchester Short Magnum cartridges is the fact that they often simply don’t provide enough advantages to most hunters to justify switching over, particularly if that hunter is already using a more established cartridge that works well for him or her. That’s a pretty major step down in recoil, especially when you take into account that you’re getting almost the same amount of performance out to 200-300 yards. 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. The two cartridges (along with others like the 7mm Mauser, 7mm-08, 7mm Weatherby, 280 Remington, 280 Ackley Improved, and 7mm Remington Ultra Magnum) use the same .284â³ bullets. Mag. 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. The WSM cases all have a .535″ rebated rim that’s compatible with a standard magnum size bolt face. They’re both great cartridges, but I’d probably lean towards the .270 Winchester. Both will work exceptionally well on deer sized game out to several hundred yards. Virtually every major brand of ammo is available in 7mm Rem Mag. 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. 270 vs 308 WIN: WHICH ONE SHOULD YOU HUNT WITH? Iâd have to compare the ballistics to double check The same goes for guns: rifles chambered in 7mm Remington Magnum are extremely popular and very commonly in the United States. This helps support the blog and allows me to continue to create free content thatâs useful to hunters like yourself. 300 WSM vs 300 Win Mag 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. I do like the 270, but the 270 Win that I have in the safe is potent enough for any deer in North America. Shooting 270 WSM and 7 Rem Mag edit b 1_2-18-2016 Vito Monopoli. Is this really the case? 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. However, Winchester made a big splash with the .300 Winchester Short Magnum in 2001 and followed up with the .270 Winchester Short Magnum and 7mm Winchester Short Magnum cartridges in 2002. 270 WSM vs 270 Winchester 14.07 fps 24.6 foot-pounds. This is an incredibly small practical difference. The .300 Winchester and .300 Winchester Short Magnum are suited for very similar hunting situations, with one small caveat. The 7mm is kind of in between, but I got a smokin good deal on it. However, as long as you can find a rifle and ammunition combination that function reliably and shoot accurately together, if using one of those cartridges improves the confidence of the shooter to a large enough degree, then by all means start hunting with a Winchester Short Magnum cartridge.
