The down side was a neck which was shorter than the caliber of the bullet it fired, which meant that the bullet had to be seated more deeply in the case. Where calculations are made, we will be sure to make clear our variables. Keep this information in mind as we start to look at the actual data comparing these two rounds. The .300 WSM is better suited for shooters who can read variables such as 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. As the bullet will take up volume which could have been taken by the propellant velocity advantages diminish as the weight of the bullet increases. And while there are better performing rounds than others, there are options in both the .300 Win Mag and .300 WSM that will give you incredible bullet energy through 500 yards. The maximum point blank range for the 12 g (180 gr) bullet is 300 yards when zeroed at 232 metres (254 yd). And again, you might look at the numbers on the graph and realize you have seen other trajectory data with much flatter trajectories but remember we are only looking at factory loads. Both are wonderful for situations like hunting mule deer in Arizona or pronghorn in Wyoming. Great article, but I’ve always felt the 270 WSM should be compared to the 30-06. All told, both are wonderful cartridges for hunting some of the larger species of North American big game or African plains game. This is illustrated in the table below comparing Federal Premium factory ammunition loaded with 130gr Trophy Bonded Tip (.44 BC) and 150gr Nosler Partition (.466 BC) bullets in .270 Winchester and 270 WSM. CVA Paramount Muzzleloader: Read This Before You Buy One! They rounded out the lineup with the 325 Winchester Short Magnum in 2005. The taper of the cartridge was reduced to provide the cartridge with more volume so as to increase its potential powder capacity. It’s still relative though, and might not make much of a difference to a lot of you reading this. And that is usually a tradeoff you get with heavier rounds. These two cartridges present an interesting case though. For that reason, the .338 Winchester Magnum is probably the closest comparison to the .325 WSM that’s in common use in North America. Now, it’s not directly correlated such as an extra inch of barrel gives you a certain amount of tighter groupings, but the physics behind a longer barrel and the impact it has on a bullet’s velocity and stability when leaving the barrel implies that accuracy would be positively affected. In reality, most rifles chambered for the .300 WSM are often a little lighter with them having a short action. The 270 WSM is by no means rare though and most sporting goods stores carry ammunition for both cartridges. There’s not a darn thing wrong with the 270 WSM either though and there’s really no reason to make a switch either if you already have a good hunting rifle chambered in either cartridge that you like. Both loads are compared when fired from a Winchester Model 70 Featherweight rifle. However, while that factor may well contribute to better accuracy, there are many other factors that influence accuracy to a much larger degree. They’re both solid performing cartridges, but I’d personally choose the 7mm Remington Magnum over the 7mm Winchester Short Magnum. Due to the power and performance of the .300 Winchester Magnum cartridge the cartridge is more likely to be employed by specialist units within a police department rather than as a general service weapon issued to law enforcement agents. The modern “magnum era” began in earnest with the introduction of the 7mm Remington Magnum and .300 Winchester Magnum cartridges during the 1960s. 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. For home defense, you don’t need the same amount of momentum. 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. This is an incredibly small practical difference. Winchester 93.8 grains of H2O (6.08 ml) With these two cartridges, we are more interested in the energy once we get out to the 100-300 yard range and beyond. The ability to zero the .300 Winchester Magnum and shoot without hold over to 270 metres (300 yd) makes the cartridge one of the flatter shooting cartridges. The .300 Winchester Magnum was designed with a neck which is shorter than the diameter of its bullet. However, both cartridges are capable of excellent accuracy in the right hands and will get the job done under most circumstances if the shooter is up to the task. Recoil from the .300 Win Mag is noticeably higher than the well-known and popular .30-06 Springfield. 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. The .300 H&H Magnum was too long for the Mauser and Springfield standard length rifle actions and required specialized rifles with a Magnum size action. backpacking. What about accuracy of the 325 WSM vs 338 Win Mag? The 300 Winchester Magnum has Case a H2O case capacity of 93.8 grains. When comparing two cartridges, the ballistics of each is always an important topic. Most likely not, but like every other category has gone, there is some variation between individual round. and SAAMI dimensional values exist for this cartridge. We will also compile this data in the applications section. All are very solid performers that are extremely popular with big game hunters pursuing game like deer, elk, black bear, and moose. If there is no issue with the rifle, there are several 190+ grain weight WSM cartridges out there that give higher BC’s than the 185grain and lighter rounds. When we talk about trajectory, we are only referring to elevation and how much a bullet will drop as it moves downrange. While we will look at each separate from the others, they should all be taken into account when determining which cartridge would be more advantageous in a certain situation. For this reason, this particular Model 70 in 270 WSM is actually longer (44″ vs 42.5″) and heavier (7.25 pounds vs 7 pounds) than the Model 70 in .270 Winchester. Wildcatters soon produced the .30-338 Winchester and Norma Projektilfabrik, who were by now manufacturing ammunition for Weatherby, took the standard length basic Weatherby brass and necked it down to .30 caliber (7.62 mm) and called it the .308 Norma Magnum. On top of that, this round has an incredibly flat trajectory at 300 and even 500 yards and a BC of .597 which will make things a bit easier when dealing with less than ideal wind conditions in the field. 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. The cartridge overall length is 72.6 mm, cartridge case is 53.34 mm in length and the bullet diameter is .308 in (7.62 mm), which is common to all U.S. .30 caliber cartridges. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges. Both the .300 Win. Let’s take a look at our ten rounds and see how they compare. Sniper Country is reader-supported. 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 300 WSM is 1/2″ shorter overall. Both of these cartridges take a 30 cal bullet (.308”) but that’s about where the similarities between these two cartridges end. The similarities in the name alone are enough to throw off those who might not be familiar with these cartridges. The 325 WSM has similar ballistics to the magnum action, medium bore 8mm Remington Magnum and 8×68 S cartridges. We are looking at the energy that is generated when firing these rounds. 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. 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 those reasons, the .300 Win Mag actually has significantly more case capacity (around 10-15% more, depending on the manufacturer) than the 300 WSM. A disadvantage of cartridge case designs with relatively large case head diameters lies in relatively high bolt thrust levels exerted on the locking mechanism of the employed firearm. The gap between the two is not as wide with the extra rounds and we are only seeing a little over two ft.lb of difference between the averages. 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. Mag. As we have seen with most of the other categories, there is a lot of similarity between these two cartridges. If it works for you, that should be all that matters. The exact size of the rifle action (which includes the locking bolt, firing pin, etc.) In today’s world, better to sugar coat it than to sound like we may be mocking. It fits actions designed for 30-06-length cartridges. The biggest difference between these two cartridges is not the ballistics, but in the rifle platforms they can be used. The maximum point blank range for the 9.7 g (150 gr) bullet is 291 metres (318 yd) yards when zeroed at 250 metres (270 yd). However, the same rifle in .338 Win Mag is advertised at 7.75 pounds and 46.75″ long overall (because it has a 26″ barrel instead of a 24″ barrel like the 325 WSM rifle). The same goes for game like mountain goat, bighorn sheep, Himalayan Tahr, and chamois. Both will work exceptionally well on game ranging from whitetail, mule, and fallow deer all the way up to elk and moose out to several hundred yards. Lighter rifles often mean a little extra recoil energy that is generated so the numbers might be a little higher for the .300 WSM rounds. Because of that, we wanted to step back and take a broad look at two rounds, one from each cartridge, that are very similar. 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. Is this really the case? Both cartridges will work really well on whitetail and mule deer sized game out to several hundred yards. Like any hunting cartridge, it’s all about matching the style of ammo with the hunting situation when thinking about its effectiveness. The .300 Win Mag Nosler Trophy Grade, AccuBond Long Range 190gr round, stands out to use from a hunting perspective. In this section, we will look at velocity, trajectory, and ballistic coefficients of the .300 Win Mag vs 30-06 to give us the information necessary to draw some conclusions for when each cartridge is best used. Not surprisingly, this results in some interesting ballistic comparisons. Additionally, the Winchester Short Magnum Cartridges all have a case with very minimal taper and a 35 degree shoulder. 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. Even at a distance of 500 yards, all rounds are supersonic with velocities well above 2,000ft.s. Still less than two inches. We can’t quantify this in our .300 Win Mag vs .300 WSM comparison. Note: these are not the only broad categories of rifle actions.
