The .300 WSM is also used in benchrest shooting. That’s no bargain. So who gets the award? I referenced everything back to .30-06 velocities and charge weights, looking for what percent increase in propellant charge gave what percent increase in velocity over .30-06 velocities. Not great accuracy, so far. I don't do compressed loads. On the other hand, the.300 WSM uses only 14 percent more fuel than the.30-06 to get an 11 percent velocity gain, a reasonable return. No self-respecting magnum cartridge of the 20th century would have shown its face on the market without the Holland & Holland belt, though very few of them—excepting the straight-walled affairs—needed them at all. As far as case capacity goes, the WSM runs on a bit less powder, but not enough to really make any sort of long term difference. It was seldom greater than EVs of any higher charge weight and definitely averaged less than other .30-caliber magnums. 300 Rem Short Action Ultra Magnum Load Data 300 Holland & Holland (H&H) Magnum Load Data 300 Winchester Short Magnum (WSM) Load Data 300 Winchester Magnum Load Data 300 Weatherby Magnum Load Data 30-378 vs .300 Win. The design has no parent case and is based off a .308 bullet with a 1:10 twist and large riflemagnum primer. The extreme variation (or EV—the highest value in one data set subtracted from the lowest) for the lower charge weight pressures was usually conspicuously higher than those of charge weights closer to maximum pressure. By and large, the 270 WSM, 7mm WSM, 300 WSM, and 325 WSM are all capable of excellent accuracy and essentially duplicate the performance of comparable standard length cartridges while fitting in a short action. It bettered the velocity of the benchmark.30-06 Springfield by over 200 fps, yet could fit in a standard long action. I’ve had some WSM rifles that fed reliably every time, and others that were a royal pain. Being short and fat, it offers a squat powder column. Its 2.1-inch case has straight walls; a steep, relatively short shoulder; and no belt. Some folks feel that the short neck of the .300 Winchester Magnum is an issue due to the fact that most of the heavier and longer bullets will be seated with the base of the bullet well below the shoulder, but I think this happens in quite a few cartridges, perhaps more than you’d think. That belt—often mistaken as making a case stronger—can cause some stretching, and often you’ll see a case separate just north of that belt. I'm just finishing up a load for my 300 wsm and and I don't know if I'll hit those speeds with a 180 accubond. In the 300WSM, 68-70 grains is a compressed load depending on which powder you use. I’ve never worries about that; the accuracy of the cartridge design removes all doubt. In theory, this leads to more uniform ignition and inherent accuracy. The 300 holds mid to upper 60s gr, so you'll end up with about 2/3 full, which would likely suck for accuracy and would put you dangerously close to detonation territory. and is not a belted case It looks like you could build one on a short action. Buy now or call to know more. ISS Prop House gives us the rundown on the guns used in Enemy at the Gate. My suggestion would be to reload a few The WSM series uses a non-belted case. The results were interesting, and in some cases they were eye-opening. 4350-class propellants often give velocities similar to 4831-class propellants. Fast forward to the beginning of the 21st century, and you’ll see the 2001 release of the .300 Winchester Short Magnum. I … The .300 WSM is adaquate for hunting moose, black bear, brown bear, elk, mule deer, and white-tailed deer in forests and plains where long range, flat shots are necessary. We look at the futuristic .450 Bushmaster and how it compares to the tried and true .45-70. It drove the .300 Holland & Holland completely out of the lime light, taking the crown as the preeminent .30 caliber magnum. I'm interested in hearing from those that have tried the Barnes 175 LRX in the 300 WSM. I selected lab data using the Speer 180-grain Hot-Cor Spitzer SP and looked for loads producing the highest velocity in a 24-inch SAAMI test barrel and how much propellant it required to reach said velocity. There are lots that work well in the Tom Beckstrand and Neal Emery of Hornady highlight the 6MM Creedmoor ammo. Variations in start load pressures are much less than in most “tall/skinny” magnums. It is the most accurate large-caliber cartridge I know. James Tarr runs through the 3-Second Headshot drill. ©2020 Outdoor Sportsman Group. All Rights Reserved. The .300 Winchester Magnum was also designed with a very short neck—0.264″ long to be precise—and has been criticized for it. It did just that, driving .30 caliber bullets (within reason) at similar velocities to the belted .300 Winchester, but it’s not as simple as that. Wow that seems fast in a 24" barrel. Suffice it to say, the .300 WSM was already one-up on my scorecard before we squeezed the first trigger. With management wanting data yesterday, we skipped them because our early screening showed unimpressive improvement over 200-grain .30-06 velocities. .300 WSM Rifles accept .300 WSM, a .30 caliber rebated rim bottlenecked centerfire short magnum cartridge. Immediately, we saw this low-pressure variation was consistently minimal in the .300 WSM. Accuracy and Tuning Ease — The .300 WSM tunes more easily and is more tolerant than any of the four 6mmBR barrels I’ve shot. The .300 WSM also head spaces off its case shoulder versus the older 300 Winchester Magnum's belted head space engineered design. Loosely based on a shortened .404 Jeffery, this short-action cartridge was designed and hyped to match the ballistics of its older Winchester sibling in a lighter rifle with a more rigid action. A lot of verbiage has described the Short Magnums as “based on” the .404 Jeffery case, but the better description is that they were “inspired by” the old British workhorse. If I could do it over, I would spend more time with 200-grain loads. Being short and squat, the angle of the magazine follower can play a huge role in whether or not the rifle will feed smoothly. Frankly, they both have a sharp, stout recoil, and that just comes with the velocities generated. Friday, March 9, 2018. Based on my experiences, there is no game animal on earth that could ever tell which of the .300 magnums it was shot with, as energy and trajectory figures are so close it’s a moot point. Before I retired I analyzed the .30 calibers from the .30-06 though the .30-378 Weatherby. And while that theory may hold water, the WSM design garners one major complaint: they don’t feed well. Nosler figures for the.300 WSM show that 61.0 grains of IMR 4350 powder will drive their 180 grain bullets to a MV of 2861 fps, and 65.0 grains of the same powder will give a MV of 3024 fps. The .404 Jeffery, at 0.545 inch, is smaller ahead of the rim than either Winchester or Remington short/fat designs; they are 0.555 inch and 0.550 inch respectively. While that may not bother some, others prefer as many ‘down’ as possible. The advantage to this round is the ballistics are nearly identical to the .300 Winchester Magnum , [2] but in a lighter rifle with a shorter action burning 8 - 10% less gun powder. Most “tall/skinny” .30-caliber cases from the .30-06 up show this. The.300 WSM is one of the more popular short magnum cartridges that have come out in the last two decades. 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. Max OAL: 2.950" Review (1) Accuracy and Tuning Ease — The .300 WSM tunes more easily and is more tolerant than any of the four 6mmBR barrels I’ve shot. It is the most accurate large-caliber cartridge I know. The WSM also posted a maximum average velocity only 49 fps less than its bigger, older brother using 14 grains less propellant. It also bests the .300 H&H's case capacity by about 10 percent. A few shots and a general overview of the Tikka t3 in .300 WSM Shows excellent linear tracking of pressure against charge weight in bullet weights from 110 to 200 grains. I’ve spun enough ink regarding my reloading concerns with belted cases that don’t need a belt, so I’ll not repeat myself here. Springfield Armory M1A Tanker .308 Review, Revolver vs. Semiauto Pistol: A Ballistic Oddity, Best Rimfire Cartridges — .22 Magnum vs .22 Long Rifle. by Philip Massaro - My Speer development team was keen to jump into learning about a new cartridge from the ground up. and 2980 fps). Tikka .300 WSM Review 05-11-2008, 13:06 Well I finally got out to the range yesterday and I am whopped! I feel the more reliable feeding of the .300 Winchester Magnum and the added magazine capacity give the edge to the older design; in addition, ammunition is much more prevalent for the belted cartridge than the WSM. Looking for previous installments of our "Head to Head" series? Has anybody built a .300 WSM rifle ? The .308 Winchester and the PPC line of cartridges have been praised for their geometry, and the .300 WSM follows in that trend. Big bore semiauto or a lever gun? For highly efficient and consistent powder burning, the.300 WSM has a short-fat powder column geometry, a concept revered by accuracy-obsessed benchrest shooters for nearly three decades. To this end, it is quite common to find .300 WSM rifles producing best accuracy at velocities of around (for example) 2900fps with 180 grain projectiles, approximately 100fps below maximum potential loads. 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.

As to the question of can a patented concept live up to promises, I believe that the .300 WSM lives up to its technical pedigree laid out in the Jamison patents and submit this evidence seen in laboratory data: The four basic methods of making rifling in a barrel are single-point, broach, button, and... Like situational ethics, standards of accuracy vary according to circumstances. It is used for both big game hunting as well as benchrest target shooting. Let’s look at those assumptions a bit closer in the following table. To get started, click the link below to visit mymagnow.com and learn how to access your digital magazine. The .300 WSM is the antithesis of the old .300 H&H. Nosler used Winchester brass and primers for these loads. .308 Win. the ballistics looks a lot like the .300 Win Mag. A lack of “pickiness” about propellant burning rates. Hodgdon’s online data shows they broke 2,800 fps with a 200-grain bullet with several propellants that we were not able to get before the Speer Reloading Manual #14 had to go to press. Shooting the .300, WSM at ranges out to 1500 yards was easier than I had planed due to its flatter trajectory , accuracy and speed advantage over the .308. If “efficiency” is getting the most output from the least input, Jamison’s concept seems to be working. We used the propellants available to us prior to the release of the Speer Reloading Manual #14 in 2007. Incidentally, we saw this same behavior in the .300 Remington Short Action Ultra Magnum that also falls within Jamison’s patent parameters. In addition, the girth of the cartridge robs magazine capacity; they're fat and take up more room in the rifle’s magazine. The fast-stepping 150 grain deer load is easy to shoot, and Both cartridges come with some points of interest—or gripes, depending on who you ask—that make them unique, and while fans in each camp fervently wave their flags, it may help if we better understood where they’re coming from. We tested three Speer Hot-Cor Spitzers (150, 165, and 180 grains) plus the 165-grain Trophy Bonded Bear Claw, available as a component then. This .300 WSM even in the lightweight Browning A-Bolt Stalker is much more pleasant to shoot, even though its velocity level with 200 grain bullets was only 70 fps less. One of the 150-grain loads roughly duplicated .30-30 velocities with superb consistency in pressure and velocity. In the Model 700, Accurate’s 4350 turned in an extreme spread … The patent details ranges of dimensions and ratios between them that cooperate to generate excellent velocities by shortening the pressure’s time to peak and by burning more of the propellant inside the case rather than in the bore. .300 WSM Rifles in stock, best price, no tax, free shipping - Call (570) 368-3920 Christensen Arms Burnt Bronze Ridgeline .300 WSM 24" 1:10" Green w/ Black & Tan Webbing Rifle 801-06033-00 That belt was designed for proper headspacing on the sloped-shouldered .375 H&H case (and the .275 H&H Magnum that barely predated it), allowing to feed properly from a box magazine while maintaining the positive headspacing characteristics of the rimmed cases. From a handloader’s perspective, I’ve found the WSM much more finicky than the belted design, or perhaps I should say that the .300 Winchester Magnum has shown to be easier to develop a load for. That’s no bargain. We later added lighter bullets. .300 WSM Rifles for sale at Scopelist. It bettered the velocity of the benchmark .30-06 Springfield by over 200 fps, yet could fit in a standard long action. To get data online quickly, we focused on the most popular hunting bullet weights. Abbreviated Name: 300 WSM TECHNICAL INFORMATION: While this cartridge is capable of digesting all of the popular 30 caliber weights, best performance will be achieved with 150 to 180 grain bullets. I've own several .308s a ,.300 WSM ,a .300 Win Mag,and a .300 RUM. In analyzing thousands of pressure data sheets, I was accustomed to seeing traditional magnum rifle cartridges show ballistic consistency issues at lower charge weights. However, we were under pressure to get data out and had to temper our enthusiasm—some things we learned came later. But the rifle is a 23" barrel and had the best accuracy in the middle of the published Quite a few cartridges now fall under this design concept, but the one that saw a meteoric rise in consumer acceptance was the .300 Winchester Short Magnum (WSM). It was so pervasive that we called it “normal” and even adjusted start charge recommendations to avoid these pressure regimes if needed. Once you do get the formula dialed in for the WSM it can be wonderfully accurate, but it’s taken me more time to get things sorted out for the shorter cartridge. We also developed reduced-recoil loads using Accurate 5744 that were very consistent. A number of 1000-yard benchrest records The .300 Blackout is here to stay, and we take some time to look at new technology surrounding this cartridge. Normally, developing loads for the .30-caliber magnums with varmint-weight bullets was a painful slog through inconsistencies, but the .300 WSM was very well behaved with 110- and 130-grain bullets. The .300 WSM magazine expands the short action double stack line to accommodate WSM calibers, SAUM calibers and the new 6.5 PRC. Setting the .30-06 as a baseline, the well-established .300 Winchester Magnum uses 37 percent more propellant than the .30-06 to attain a 13 percent increase in velocity. I have seen some issues with the overall length of the case preventing some of the modern bullets—with the really long ogives—being able to function through the magazine in some rifles, but I suppose that comes with the territory. The .300 Winchester Short Magnum comes with other issues. So far I've worked with R 17 (64.3grs. We ping steel with a .300 WinMag at over a mile.

I don’t feel comfortable saying I wouldn’t hunt with the .300 WSM, but I do feel comfortable saying that if someone were building me a rifle and I had to choose between them, the .300 Winchester Magnum would get my vote every time. Video comparing the ballistics for the 300 Win Mag and the 300 WSM. This means the .300 WSM In my load above, I get 2900 fps, +/- … I've been plaint with two 300 wsm's for about a year, one really likes 64g of rl17 with 165/168 grain noslers, the other starting shooting really well with 64g of hybrid 100 and 180 grain noslers. ITEM CAP W L H.CAL.CAL MAX OAL 00100-0006 DSSF 3RD.97 3.055 2.51 300 WSM 6.5 Subscriber Services. H380 was the most accurate powder with these bullet weights. The WSM also posted a maximum average velocity only 49 fps less than its bigger, older brother using 14 grains less propellant. It provides high speed and excellent accuracy with 125- to 180-grain bullets in the .300 WSM. | I did a lot of 100 to 500 yard testing with the 168 gr AMAX because this is about as far as most people will target shoot and it is within the area most people do their hunting. The.300 WSM, an original Winchester design, fits handily into bolt-actions sized for a cartridge length of 2.860 inches. Today, I would change both my mind and the copy I wrote about heavy bullets in the Short Mags. The differences in action length and rigidity haven’t shown up either, as I truly don’t mind carrying a .30-06-length action anywhere. New features have been added by Accurate Mag to the magazine, including a manufacturing process and a new heat treatment, as well as “.300 WSM” imprinted on the back for better identity of the magazine. I was just wondering about accuracy, dose this round have We also screened the 200-grain Hot-Cor—more on this later. We later added lighter bullets. Both cartridges have a similar recoil; I feel that the differences in felt recoil are more attributable to stock design and fit than to recoil energies generated. Yes, the .300 WSM Winchester Short Magnum is A GOOD CHOICE for elk hunting, under average conditions, from a mid-range distance, with a medium grain expanding bullet, and with correct shot placement. All Shooting Times subscribers now have digital access to their magazine content. The rule of thumb is that a cartridge should have a neck length of at least one caliber, but I’ve never seen an issue with neck tension in any .300 Winchester, no matter how long or short the bullet. On the other hand, the .300 WSM uses only 14 percent more fuel than the .30-06 to get an 11 percent velocity gain, a reasonable return. Give a Gift Increases in velocity over that of the .30-06 are virtually linear with the increase in propellant, unlike more conventional “tall/skinny” .30-caliber magnums. Cartridge Type: RifleHeight: 2.1\"Width: 0.533\"Average FPS: 3078Average Energy: 3576Average Gr: 170Recoil: 2.36Power Rank: 5.23 of 20 The .300 Winchester Short Magnum (.300 WSM) was designed in 2001 by Winchester Repeating ArmsCompany. It has a range of bullet weights from 125 to 200 grains though most would agree that the 150-180 gr bullets often work the best with the cartridge. Mag: Ballistics, Cost, and Accuracy It might sound crazy, but these two popular hunting cartridges have more in common than you think. Next, we pit subsonic rivals against each other before stretching the legs of this CQB round out to 600 yards from a short 9-inch barrel.
