Both were based on a severely shortened H&H belted case, and both had a rough start. Mag. Our infatuation with short-action cartridges dates back over a century, what with the .250-3000 Savage and .35 Remington—just to name a couple—having celebrated their 100th birthday some time ago. Of the second round of short-action magnums, Winchester had first to see the light of day. lol .300 saum is about $65 a box and you can get decent .300 wsm for $35. The 300 wsm or the 300 saum I will be shooting about 500 rounds a year. In truth, the .300 WSM runs a bit (though not significantly) slower than its bigger brother, and in some rifles, demonstrated serious feeding issues. Sicherlich wurde die .300 Win. Man kann sagen, es ist nunmehr eine veraltete Patrone. While providing ballistic performance nearly identical to that of the .300 Winchester Magnum, .300 WSM does this with about 14 grains less powder. The .300 WSM is the antithesis of the old .300 H&H. So, assuming that you’re in the market for a rifle chambered for one of these short-action magnums, which of the two designs makes more sense? First, the .300 WSM is, was and shall be the more popular of the two choices, and I believe that is a result of better marketing, and better marketing only. Larry, Why would you select the 270 wsm over the 7mm or 300 wsm . The following ammunition cartridge ballistics information and chart can be used to approximately compare .300 AAC Blackout vs .300 WSM Winchester Short Magnum ammo rounds.

In fact, the felt, or perceived, recoil is less than my .270 Win. The shorter datum line (distance from the base of the cartridge case to the beginning of the shoulder) of the RSAUM case, coupled with the lesser shoulder angle when compared to the WSM design results in a cartridge that, in my experience, feeds more reliably than the WSM does. The .300 WSM has found a place in the market, while the .300 SAUM is already obsolescent. AS far as recoil goes my 300WSM is not bad at all. But the concept of loading a magnum cartridge in that short, rigid receiver held its allure; the short, squat powder column is believed by many to help in the accuracy and consistency department. erreichen. As far as the discussion between the 300 short mag and the 7mm mag I think you are splitting hairs. Where the RUM case is a 2.85-inch, magnum-length affair, the .300 RSAUM is only 2.015 inches long, with a 30-degree shoulder. A mate took this wild boar with his 300wsm. forum.accurateshooter.com/threads/what-to-go-with-300-saum-or-300-wsm.3860367/, Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36. Which is the more readily available and dependable? I've heard that reloading 300 WSM can be finicky (even seen guys get jammed in the … In anything other than a properly built rifle, the cartridge will hang up, jamming the bullet nose into the feed ramp, and creating all sorts of frustration. Gold $$ Contributor. Being beltless (again both the WSM and RSAUM are based on the beltless .404 Jeffery case) the .300 RSAUM’s shoulder offers enough of an angle to offer positive headspacing, yet feeds rather well for a short, squat cartridge. But, the success of the release of the .300 WSM yielded the subsequent release of the .270, 7mm and .325 WSM cartridges. Please note, the following information reflects the estimated average ballistics for each caliber and does not pertain to a particular manufacturer The .300 RUM is based on a blown-out .404 Jeffery with a rebated rim, generating velocities among the highest available. Mag. 175rltw Senior Member. With good hand loads, there really isn't much difference. If that isn't fast enough for you than you can rule out the 300 WSM. A slightly rebated rim—presumably to share the same bolt face as the H&H-based cartridges—and squat, voluminous body, with a steep 35-degree shoulder for good headspacing, the .300 WSM made quite a splash. Did do some quick load comparisons for 300 wn with 215 gr Hybrid target vs 284 win mag with 183 SMK. The 7mm-300 wsm is a wildcat with a slightly longer neck favoured by target shooters. Nov 20, 2016 #12. Among the .300s, when you look at the dimensions of the two cases, it seriously boils down to nothing more than a popularity contest. It's probably not worth rebarrelling in reality but it was just a thought. Mag. It fits actions designed for 30-06-length cartridges. Mar 19, 2005 #5. Background: I spent the better part of 2 years trying to develop an accurate load for my 700 BDL in .300 SAUM. From what I have read, it sounds like the 1:11 twist will stabilize the 200 gr Accubond. A 300 SAUM-Ackley might shave a couple grains off a WSM load while achieving the same speed, but that seems like a poor tradeoff when you need to buy all custom (dies, reamer) and fireform to get going when compared to a WSM with off the shelf stuff everywhere ready to go. l Seven in .300 SAUM … The &mm WSM vs the 7MM Rem SAUM, there is quite a bit of difference, same with the 300 WSM vs the 300 SAUM . 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. It also bests the .300 H&H's case capacity by about 10 percent. I'll second the 7mm Sherman Short as a great alternative to 7 SAUM It offers velocities on par with the WSM variant, with both pushing a 180-grain bullet at 2900 fps, compared to the 2960 fps which is standard for the belted .300 Winchester Magnum. In the same class as the .300 short magnums is the .325 WSM. The latter 2 are slightly different. Mag.

It bettered the velocity of the benchmark .30-06 Springfield by over 200 fps, yet could fit in a standard long action. First, the .300 Win Mag is a lot longer. 284 win at 2850 give you 6.6 mill drop with 1.31 mil drift 10 mph cross wind. is a classic “standard-length” cartridge based on the belted 375 H&H Magnum case. It was shot from 200m and expired less than 30m away after a short run. The .300 WSM cartridge has certainly proven itself—it has plenty of killing power, and will truly take any game animal that a .30-caliber will take—but if your hunting rifle doesn’t feed right, you will end up frustrated. 7 WSM has a short neck (which may adversely affect bullet alignment in bore). The 300 WSM would be my choice of the two.

That said, I've seen many more rifles chambered for the WSM than I have for the RSAUM, though the latter has a small, yet fervent fan base. Allerdings wird man noch etwas warten müssen, bis Laborierungs- und Waffenangebot in .300 WSM den Standard der .300 Win. Hot on the heels of the .300 WSM, Remington countered with the .300 Remington Short Action Ultra Magnum—or RSAUM for short—based on a shortened version of their 1999 .300 Remington Ultra Magnum cartridge. Second, I feel that the RSAUM design has, and always will, feed better than does the WSM design. The .300 WSM also head-spaces off of the case shoulder, versus the older .300 Winchester Magnum's belted head space design. That said, among the WSM cartridge line, the .300 seems to be the only one maintaining a serious presence; even the .270 WSM is falling off considerably, and the 7mm and .325 WSMs are apparently down for the count. A question for reloaders of .300 short mags: What issues have you encountered when trying to develop consistent loads for the short/fat mags and how did you overcome them? Winchester's 300 WSM and 270 WSM are solid rounds that sell well. Are you saying .300 wsm is $50 a box? I currently have both a 700 Remington and a M77 Ruger type rifles. Thread starter #5. by Philip Massaro - The 300 WSM has slightly more case capacity and Winchester did a better marketing job, making it a very popular short mag. Both are faster than the .30-06 Springfield, and both give highly usable velocities, especially from a short, light rifle. The 300 Win. In the true 7mm wsm the shoulder has been moved forward a little to stop it chambering in the 300wsm chamber. The .325 WSM is intentionally misnamed to make it sound bigger than it … Actually, I wish the RSAUM design were more popular, because the shorter case allows bullet with a longer ogive to be seated further out from the case mouth. is rare, but still draws breath, and the 6.5 Rem. The .300 SAUM case is a bit shorter while the .300 RCM and .300 WSM cases are the same length.

Thirdly, the volume of the RSAUM case is lesser than that of the WSM; looking at the reloading data you’ll see a 50 to 60 fps advantage for the WSM case. .300 Remington Short Action Ultra Magnum (also known as 300 RSAUM, 300 RSUM or 300 Rem SAUM) is a .30 caliber short magnum cartridge that is a shortened version of the Remington 300 Ultra Mag, both of which derive from the .404 Jeffery case. vs. .300 Win. In a properly tuned rifle—with a good magazine follower and well-polished feed ramp—the WSM will feed just fine. The short and fat .300 magnums are no better than other magnums of the same caliber, but the author likes them because by working in a short action, they help trim ounces from lightweight rifles like the Browning A-Bolt Mountain Ti in .300 WSM (top) and the Remington Mode. Looking for previous installments of our "Head to Head" series? Major rifle and ammunition manufacturers have supported the .300 WSM and presently Remington have also adopted the .300 WSM in their M700 rifle line, the .300 SAUM barely surviving as a chambering for the model 7 rifle. I have been debating the same thing as OP. A longtime favorite among the precision rifle community, the WSM and SAUM line of cartridges are able be ran reliably from the Accurate Mag .300 WSM/SAUM DSSF Magazines. I am leaning towards the 300 WSM and then getting a long action bolt stop and a couple of the Hells Canyon Armory magazines that are made to allow the WSMSAUM lines of cartridges to run with a greater overall length.

The target community shows an accuracy advantage for the RSAUM design, though there are truly no flies on the WSM; both have been wonderfully accurate with bullets from 150 to 200 grains. Both rifles work equally as well. 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. A .308 diameter, 180-grain bullet with a muzzle velocity of a little over 2900 fps, is a .308 diameter, 180-grain bullet with a muzzle velocity of a little over 2900 fps, whether it's fired from a full-sized .300 Win Mag, a .300 WSM, a .300 SAUM, a .300 H&H Mag, a .308 Norma Mag, or the new 300 Ruger short magnum. The 300 Win Mag is definitely faster than the 300 WSM. vs. .458 Lott• 7mm Rem. Should you want the short magnum experience, and should you settle on the WSM design, make sure the rifle you choose feeds cleanly and reliably.

The short, fat 300 WSM, released on an unsuspecting public in the second year of the 21st century, boosts that slightly to 3,010 fps and 3,621 f-p. Hot on the heels of the .300 WSM, Remington countered with the .300 Remington Short Action Ultra Magnum—or RSAUM for short—based on a shortened version of their 1999 .300 Remington Ultra Magnum cartridge. The .300 Winchester Magnum—that belted affair based on a shortened Holland and Holland case—was released in 1963 as the last in a quartet of cartridges that redefined magnum performance to the masses. The increase in length of the .300 WM over the .300 WSM is greater than the increased wideness of the case of the .300 WSM. The 2001 release of the .300 Winchester Short Magnum (WSM) saw the first serious threat to the hallowed .300 Winchester Magnum since its release in 1963. They are very similar in performance. The .308 Winchester went on to ‘standardize’ the short-action, being released in 1952, and the magazine length for that cartridge was the basis for a couple of early short-action magnum cartridges: the 6.5 Remington Magnum and the .350 Remington Magnum.
