Additionally, the .300 Win Mag has a shoulder moved further forward than the 7mm Rem Mag. However, while that factor may well contribute to better accuracy, there are many other factors that influence accuracy to a much larger degree. Due to the shoulder safety design, the neck is very short. I’ve always thought the 270wsm was similar to the 7mm Mag. 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. The differences in external dimensions between the .270 Winchester and 270 WSM obvious in the photo below. Due to the long running popularity of 7mm cartridges like those just mentioned, there’s a great selection of quality bullets to choose from for both cartridges. They’re both solid performing cartridges, but I’d personally choose the 7mm Remington Magnum over the 7mm Winchester Short Magnum. The .270 WSM is a good cartridge but, honestly, it is a very small player in terms of market share. 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. 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. 08-06-2007, 12:56 AM. There is a decent selection of factory ammo available in the cartridge from companies like Federal, Hornady, and Winchester. After all, fans of the Winchester Short Magnum cartridges like to point out the benefits of the shorter and fatter powder column. 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). Both cartridges use cases derived from the long, belted .375 H&H Magnum. It also carries a tad more energy out to longer range and is capable of excellent accuracy. I shot a 270 for years think it's one of the best deer cartridges made.I did own a 270wsm for awhile and it performed well also.I now shoot a 7mm mag . The following ammunition cartridge ballistics information and chart can be used to approximately compare .270 WSM Winchester Short Magnum vs .300 Winchester Magnum ammo rounds. However, 200 grain, 225 grain, and 250 grain bullet weights are most common for .338 Win Mag factory ammo. Specifically, the new 270 WSM, 7mm WSM, 300 WSM, and 325 WSM cartridges were all designed to use a very compact case that would fit in a short action rifle. ammo seems the same price but 7mm is alot easier to find. In this article, I’m 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. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges. I think we can agree that most hunters and shooters in North America are probably familiar with the venerable .270 Winchester, 7mm Remington Magnum, .300 Winchester Magnum cartridges. Basically, their stated goal was to give shooters and hunters all the benefits of a short action cartridge (like the .308 Winchester pictured below) with essentially the same external ballistics as comparable standard length cartridges (like the .270 Winchester cartridge in the photo below).So, how’d they do it? By David E. Petzal. The .270 Winchester is one of the most popular centerfire rifle cartridges in North America and is very likely among the Top 10 (maybe Top 5) best selling rifle cartridges in the United States each year. I hate belted cases, and I own a 270 WSM, but I'd recommend the 7mm Remington Magnum anyway, unless there's some reason not to. 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. I’m not sure if it cracks the  Top 10 best selling rifle cartridges in the United States each year, but it’s likely in the Top 15 or Top 20. This specific model weighs 7.25 pounds when chambered in both 300 WSM and .300 Winchester Magnum. 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. 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. What about accuracy of the 325 WSM vs 338 Win Mag? I would stick with the classic 7mag only because I love the "classics" and because the ammo would be a lot easier to find in in the stores. 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 Hornady loads fired the same bullet with a scant 30 fps of difference between them, with the .300 Win Mag having a tiny velocity edge. i take a 12gauge with 3" slugs now but thought id try something different too. Robby Denning - November 16, 2015. This specific model weighs 7.25 pounds when chambered in both 7mm WSM and 7mm Rem Mag. The 270 WSM and 325 WSM are more of a mixed bag, but offer advantages to hunters in certain aspects as well and this is reflected in their popularity in particular segments of the hunting community as a whole. Both are wonderful for situations like hunting mule deer in Arizona or pronghorn in Wyoming. While I would not describe the 7mm WSM as a rare or hard to find cartridge, it’s not especially popular or widely available. While rifles like the Winchester Model 70 were produced in that chambering for several years, I’m not aware of any rifles currently manufactured in 7mm WSM. Both have their good points. 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. 300 Win. Indeed, it’s even possible to see that much shot to shot variation within the same box of ammo for a particular cartridge. Shooting 270 WSM and 7 Rem Mag edit b 1_2-18-2016 Vito Monopoli. 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. Looking at it that way, it’s not surprising that the 7mm WSM is likely on its way out. 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. The 270 WSM is relatively popular itself (probably the second most popular Winchester Short Magnum cartridge behind the 300 WSM), but it can’t hold a candle to the .270 Winchester in terms of overall availability. The 300 Winchester Short Magnum likely does gain some accuracy benefit from its shorter powder column. 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. Those factors result in this particular 300 WSM load having about 7% less free recoil than the .300 Win Mag. But just like with trajectory though, they are close enough that you can say they have essentially the same amount of wind drift. With the whims of the marketplace it may or may not stay readily available. 7mm mag vs 300 Short mag by: PB I have owned a Remington 7mm mag rifle(s) and used it almost exclusively for hunting deer, elk and moose since 1968. Finally, the two cartridges use the same .308″ diameter bullets and there is a big overlap in typical bullet weights for each cartridge. 7mm Mag, not so much. CVA Paramount Muzzleloader: Read This Before You Buy One! I've only shot one deer but that was with the .270WSM from 275 yards.My brother has shot alot more deer than I have and he uses a 7mm Rem Mag.Last year he shot a doe from 310 yards with his.I would go with the 7Mag since the ammo is alot easier to find.Both will kill a deer dead as a doornail though. The 7mm Winchester Short Magnum very likely does gain some accuracy benefit from its shorter and fatter powder column. Much more versatility if you ever need the bigger bullets. As you can probably guess, there is very little difference in the trajectories in the two cartridges. 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. But off the top of my head it would seem to be the case. that. However, though the .300 Win Mag (like the 7mm Rem Mag) is derived from the .375 H&H Magnum and uses a fatter case than cartridges like the .270 and .30-06, the 300 WSM still has a much fatter case with less taper and a steeper shoulder angle (35 degrees vs 25 degrees). The 7mm WSM, 25 WSSM, and 223 WSSM are the guests of honor at a wake near you. 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. Again, probably not. Let me know if you have any questions or requests. 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). So with that said, there’s absolutely nothing wrong with the 300 WSM either I understand why other hunters prefer the 300 WSM. The answers to the above questions really depend on the rifle, ammunition, and shooter in question though. The Winchester Short Magnum line of cartridges is a good example of how even well designed products that largely accomplish the goals set by the manufacturer can fail to catch on with the hunting community. I have killed elk with ,260 rem, 6.5 x 284, 270 win, 270 wsm, 7mm saum, 7mm rem mag, 300 wsm. Cartridge (Wb@MV) Rifle Weight: Recoil energy: Recoil velocity.17 HMR (17 at 2550) 7.5: 0.2: n/a.17 Hornet (20 at 3650) 8.5: 0.6: 2.0.17 Rem. However, other cartridges, like the 6.5 Creedmoor and .308 Winchester (which have overall lengths of 2.825″ and 2.81″ respectively), are about a half inch shorter and will therefore fit into what’s commonly known as a “short-action” rifle. 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. Of course, this is not always the case and some rifles chambered in 7mm WSM rifles feed quite reliably, but it’s more of an issue with that cartridge that’s not as often encountered with the 7mm Rem Mag and its longer, slimmer, and more tapered case. The 325 WSM shoots .323″ bullets while the .338 Win Mag uses .338″ bullets. 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. They rounded out the lineup with the 325 Winchester Short Magnum in 2005. 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. I have both. The situation with rifles in is pretty similar. Once again, there is essentially no difference between the recoil of the two cartridges though. Before we get started, I have an administrative note: Some of the links below are affiliate links. I do like the 270, but the 270 Win that I have in the safe is potent enough for any deer in North America. but which would get the nod and which would you pick and why? Both rifles in this case also have a 3 round magazine as well, so there’s no advantage there with either cartridge. 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. First, the .300 Win Mag is a lot longer. Find a good gunsmith and get a muzzle brake! Between the .270 WSM and the 7mm mag, the 270 will have the higher ballistic coefficient and sectional density, given that both bullets are of the same type and weight. In addition to potentially giving up a little bit of magazine capacity due to the fat and stubby design of the 325 WSM cartridge, those same traits (along with the cartridge’s very steep shoulder angle) can sometimes present feeding problems. Both cartridges will work really well on whitetail and mule deer sized game out to several hundred yards. For that reason, the .338 Winchester Magnum is probably the closest comparison to the .325 WSM that’s in common use in North America. I think its inherantly safer and will last longer. Mag. Like most ballistic and other performance specs we have looked at between the 7mm Rem Mag vs .300 Win Mag, there is not a whole lot of difference between the two cartridges. Im sure someone will disagree with me but they are not even close to equal when you compare what it takes to get the velocities close to the same. 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. 270 vs 308 WIN: WHICH ONE SHOULD YOU HUNT WITH? Maybe more, but can't remember. 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. The fact of the matter is that regardless of the rifle cartridge in question, the shooter is almost always the weakest link in the accuracy equation. Source(s): 270 wsm 7mm rem mag: https://shortly.im/wynVp. The verdict? 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. 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. 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. Of these, 140 grain, 150 grain, 160 grain, and 175 grain loads are by far the most common. 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). Is it significantly more accurate than the .338 Winchester Magnum? Ive never shot a 270wsm so Im not sure about that one. I guess riflemen are becoming the 270 wsm operates at around 63000 psi and the 7mm stays around 54000 psi. 3rd installment in my caliber vs caliber series. As a quick aside, the choice of a .323″ (8mm) bullet diameter for the 325 WSM was a pretty big surprise to the shooting industry, which was expecting Winchester to release a 338 WSM instead.
