The Coast Guard uses them to put big holes in bad boats, but for hunters, bullets in the 250 to 350-grain range will be the most useful. I use a small brass catcher on it even when hunting, so far no problems with it. Buffer springs, unique magazines, different bolt, etc., are required. One of the most important dimensions on any AR is the size of the gas port. They must be loaded to a narrow pressure. This cartridge, however, the .458 SOCOM (.458 Special Operations Command) was reportedly given birth over a barbeque and some cold brew. Over the chronograph, velocity 15 feet from the muzzle measured 1,927 fps with a deviation of 18 fps — very consistent performance — and it showed on the target. Of course, all of these other cases soon outperform the .458 SOCOM as bullet weights get heavier since they have the case capacity to push the 400-, 500- and even 600-grain heavy weights much faster. The one component that is currently in short supply is cases. Most.450 Bushmaster ammo typically has bullet weights in the 158gr to 300 gr range, with 250gr and 260 gr bullets being the most popular. If you're tough enough to take the challenge, high mountain country can be a Mecca for the serious whitetail hunter. “So, the primary reason for the .458 HAM’R was to achieve more velocity and a flatter trajectory and longer-range bullet expansion.” That puts it squarely in the territory of the modern .45-70 or .450 Marlin, and it will do anything those rounds will do. It's a size and timing thing. The Coast Guard uses them to put big holes in bad boats, but for hunters, bullets in the 250 to 350-grain range will be the most useful. ArmaLite engineers simply took their .308 AR-10, made it smaller, chambered and timed it for a new, hot .22 based on a blown-out .222 called the .22 Special, later named the .223, and resubmitted it as the AR-15. Corbon factory loads with what appears to be a 300-grain Sierra FBHP were the only loads I had available. There are several ways new cartridges come into the world. You get the TAC-15. I fired about 50 rounds downrange, all fed from standard 10-round .223 magazines. I have it on good authority that DPMS will be offering an A2 buttstock with a real recoil pad in the near future.

Velocity drops fast, and they slow way down and go subsonic, precisely as the design required. Considering the recoil energy of 458 Socom, we recommend an eye relief of at least 3.5 inches or more. The .308, .223, 7mm Mauser, and venerable .30-06 were all created this way. That's the where and why of the super-heavy 450-, 500- and 600-grain bullets. The standard hard plate, more than adequate for the .223, is a real meat grinder with the .458. A 300-grain, well-constructed bullet moving at about 2,000 fps is 150- to 200-yard bad medicine for just about anything, including bear and moose. Outstanding marine fishing is available from coastal piers. Budget. The Rock River line is known for quality, and this rifle is no exception. Verify range and wind, aim a foot high of the boiler room and you are having venison for supper for the next few months. These were the design limitations Marty ter Weeme had to work around to give the little AR-15 real muscle, but it didn't stop there. Then, of course, you have the "wildcatters" who take everything out there and neck it up and down just to see what happens. Much of the research on the capabilities of big-bore AR-15 rounds like the .458 SOCOM concentrate in the area of subsonic (1,050 fps and lower velocities) and suppressed loads. Join now. No one will argue the effectiveness of those cartridges on deer, but for bear, elk, and moose, the job had to be left to its bigger, heavier brother, the AR10 — where the mega rounds are found. Its bullets range in weight from 250-600 grains and are available in both subsonic and supersonic variants. The .458 SOCOM (11.63×40mm) is a moderately large round designed for a specialized upper receiver that can be mounted on any AR-15 pattern lower receiver. Most .458 SOCOM bullets fall on the lower end of the spectrum of grain weight (less than 400 grains) but for those looking to suppress their AR the heavier grain bullets are typically tuned for suppressed hunting. The Beowulf uses 325 and 400 grain bullets at 1950 ft/sec and 1800ft/sec. The.458 SOCOM uses 200gr to 600gr bullets, with 250gr, 300gr, and 350gr being the most common. Now, your .223 AR has morphed from a varmint getter to a full-fledged deer-, bear- and elk-stopper by simply changing the upper — no new FFL transfer required. The rising popularity of the AR-15 and its rapid move to the dark timber has generated a need for that kind of muscle in the AR. All rights reserved. For hunting medium to large game, bullets in the 250 grain– … For all the myriad of aftermarket parts available for ARs, volumes of catalogues or aftermarket goodies, no one offers an A2-style buttstock with a real recoil pad.

It's certainly big enough for elk, and there's not a deer alive that will walk away from a solid hit. Research had indicated that a short belted cartridge called the .458 × 1.5" Barnes had been adopted for use in suppressed bolt-action rifles for use in SE Asia during the Vietnam War. One is the military. The .45 Professional was ruled out because, in an interview with industry press, the developer of said cartridge stated that steel proprietary to General Motors was used in the bolts and extractor to withstand the high operating pressures. No more. As is often the case with government requests, about halfway through the trials, the higher brass decided the emerging dust-up in Asia would be a close quarter affair, and it might be better to abandon the bulkier, heavier .30 caliber and move to a smaller, lighter, faster round. This is important for any cartridge, not just the 458 Socom. A lot of powder room was left in that case. I am not surprised. The case headspaces on that minimal shoulder (see drawing).

In 2000 a sledgehammer cartridge that would launch 250- to 600-grain .45 caliber bullets from a standard size AR-15 with a proper barrel and chamber was born — enter the .458 SOCOM. Looks like the .458 SOCOM shooting the 300gr Barnes TTSX zeroed at 100 will be about 13.5 inches low at 200 and dropping fast after that.

This material may not be published, broadcast, rewritten or redistributed. While the effective range of the .45-70 on individual targets was limited to about 1,000 yards (915 m) with either load, the heavier bullet would produce lethal injuries at 3,500 yards. Combined with the wide selection of bullets available in .458 diameter, this cemented the choice of caliber. The initial prototype brass still bore the .50 AE head stamp and this has caused some confusion, as the SOCOM case is longer with a narrower rim. The case length was chosen to be compatible with the Barnes 300-grain X Spitzer bullet.

It's a very easy case to load for, as long as your dies don't push the minimal shoulder back. The real cleverness in the design of the .458 SOCOM is that nothing but the upper need be changed — same magazine as the .223, same buffer spring in the buttstock, same everything. For long range shooting, 6-inches or more would be ideal. Lastly, what we always love about Tromix is that their reputation is built not only on quality and high-performing parts, but the fact that all their parts are hand-made and individually inspected. The cartridge case design was finalized based on discussions with Tony Rumore at Tromix suggesting a lengthened .50 AE case would work well in the magazines as well as be the largest diameter case to be able to feed through the barrel extension. “I felt that if the effective range of the SOCOM could be increased to over 200 yards we’d have a much more versatile cartridge,” said Wilson. After the accuracy testing, the more precise, higher-magnification scope will be replaced with either a 3X or 4X ACOG or a red dot for faster target acquisition.
