The .473-inch/12mm-diameter rim was designed in 1888 for the German Commission Rifle chambered in 7.92×57mm Mauser cartridge, and is arguably the most common rim size globally, as all bolt actions chambered in cartridges derived from that shell, such as .30-06 Springfield, .308 Winchester or cartridges derived from them share this rim size. 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. .458 SOCOM was originally spec’ed for use against highly chemically-altered humans, such as Somali rebels high on khat, against whom the 5.56 in the M4 platform simply wasn’t up to the task. It seems it took multiple hits to permanently take the opposition "out of the game" in Mogadishu, Somalia. Corbon factory loads with what appears to be a 300-grain Sierra FBHP were the only loads I had available. Big, heavy bullets moving at moderate velocities are proven game-stoppers when a fast stop is the vital objective. 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. 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. Buy in bulk & save even more! Its bullets range in weight from 250-600 grains and are available in both subsonic and supersonic variants. It’s a good idea to buy a scope that fits into your budget. On the other hand, I hope until this reviews about it What Is The Effective Range Of A 450 Bushmaster And Upper For 458 Socom will possibly be useful. One is the military. ArmaLite's entry, called the AR-10, was a semi-auto of simple design (with a full-auto option) chambered in .308. I use a small brass catcher on it even when hunting, so far no problems with it. The website dedicated to the .458SOCOM, where load data and other info also available. The .50 AE rim diameter was reduced from .514 inch to .473 inch for compatibility with other platforms, primarily bolt-action rifles. A .458 SOCOM at 600-grain almost becomes absurd on a deer at close range, like using a Glock on a gnat. I too am thinking about a bear hunt with it up in Northern Minnesota. A bit on the results before I go on. The cartridges considered were 7.62×39mm, 9×39mm Grom, .45 Professional (which has since become the .450 Bushmaster), and .50 Action Express. An expert offers some tips for night fishermen. With muzzle energy in the same class as .308 Winchester, the .458 SOCOM provides a significant punch for short-range use. The standard hard plate, more than adequate for the .223, is a real meat grinder with the .458. The Brush Country of south Texas is usually hot, dry, and covered with thorny brush thick enough to stall a bulldozer. The .308, .223, 7mm Mauser, and venerable .30-06 were all created this way. 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. I've always been a fan of the 45-70 and have lever actions and single shot rifles, the 458 Socom just seemed a great idea! The consensus was a one-shot stop would sure be nice. There was never a failure to feed, it never jammed, or gave me a problem of any sort. With the introduction of the .458 SOCOM, the trim AR-15 is more than tough enough for the big guys. Can this product of a barbeque and a cold brew become the next deep-woods superstar? Bullet choices are vast with Nosler, Hornady, Barnes, Speer, Woodleigh, Swift, A-Frame, Sierra, and Lost River all offering great bullets in .458 from 250 to 600 grains. 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 Government bought it, Colt bought the design rights from ArmaLite, and AR-15s wearing a Colt logo tromped the rice paddies of Vietnam for years, going on to become the primary military firearm to this day. The heavier 500 grain bullet produced significantly superior ballistics, and could reach ranges of 3,500 yards (3200 m), which were beyond the maximum range of the .45-70-405. Traveling here to there, a little fishing might be good for what ails you. - YouTube SOCOM. Barrel: 16" 4150 Parkerized Heavy Barrel Twist: 1:14 Caliber: 458 SOCOM 12" Free Float Handguard ACME AR-15 Upper Receiver. This is important for any cartridge, not just the 458 Socom. It's a very easy case to load for, as long as your dies don't push the minimal shoulder back. No more. Other cartridges like the .450 Bushmaster or .50 Beowulf were created to fill this void. The case headspaces on that minimal shoulder (see drawing). It would quiet things down quite a bit and probably add a bit more velocity. Many Somalis would chew the drug Khat all day and the effects of the drug would both curb their appetite (in a country plagued by famine) and increase their pain tolerance. But were I to have their ear as to the design, it would have an elevated optical platform (EOP) to get the scope up a bit higher, and a real recoil pad! "So, as you can see, the SOCOM is maxed out at 125 yards and the HAM'R at 200 yards, which is a 75-yard gain in effective range with 2.5 inches less drop at 200 yards. Read some of his stories about black bear hunting. [citation needed] Marty ter Weeme of Teppo Jutsu designed the cartridge in 2000 and Tony Rumore of Tromix was contracted to build the first .458 SOCOM rifle in February 2001. It can also double as an effective hunting cartridge at short ranges, even on big game. One of the most important dimensions on any AR is the size of the gas port. 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. Maybe they have a magic trigger finger. What do you get when you cross an AR-15 with a crossbow? 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. 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. Other loads for reloaders are available from the Teppo Jutsu Web site, and a lively reloading discussion is always underway at the .458 SOCOM Forum. In my opinion, 200 yards is this rifle's practical hunting range. I say "claimed" with the .458 SOCOM, because that's what the designer's say in their sales hype, but other sources say it's more like 1,750 to 1,800 fps, or, about the same as the .45-70. Considering the recoil energy of 458 Socom, we recommend an eye relief of at least 3.5 inches or more. The project sponsor set forth a number of specific requirements namely that the cartridge had to fit in the M4 carbine and be capable of firing heavy-for-caliber projectiles at subsonic velocity using suppressors. We accept returns. 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. 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. Dies ordered from Hornady have not yet arrived. That makes it an effective cartridge for urban combat when punching through walls, engine blocks, and heavy doors is necessary. Short cases moving heavy projectiles at moderate velocities are usually capable of excellent accuracy, but this is exceptional. If you searching to check on Max Effective Range 458 Socom And Mp 300 In 458 Socom price. 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. In the world of bolt actions, levers, single-shots, and even handguns, hunters have an abundance of big-bore .45 caliber options to choose from, ranging from the .458 Winchester down to the .454 Casull. Even at the claimed 2,000 fps, of comparable lever gun choices, it only actually exceeds the .45-70 . As noted above, the cartridge was designed to be 100% compatible with the M4 platform. I have it on good authority that DPMS will be offering an A2 buttstock with a real recoil pad in the near future. Tool Craft 458 / 450 Mil-Spec Bolt Carrier Group Nitride The rifle is fitted with the Rock River match trigger, but no other modifications are made — pretty much stock as delivered by Rock River Arms. Want to wear when you're heading into the wild? Both Remington and Winchester produce bulk bullets in .458. It's certainly big enough for elk, and there's not a deer alive that will walk away from a solid hit. If you're like me you soon get pretty suspicious of gun writers who seem to get sub 1-inch, 100-yard groups from everything they shoot. 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. 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. Rock River offers either complete rifles or just uppers in .458. 458 Socom 8 Inch Pistol Ballistics And 458 Socom Max Effective Range is best in online store. That's the where and why of the super-heavy 450-, 500- and 600-grain bullets. Get an inside look at this hunting weapon. [citation needed]. A+ customer service. Good shooters will no doubt stretch that a lot, with high BC bullets, but big game is way different than steel gongs. The energy of such a combination is 2,400 foot-pounds at the muzzle and, within 100 yards, it doesn't weaken much. Back in the late '50s, the military decided to replace the venerable Garand. This factory load from this unmodified rifle never exceeded 2 inches at 100 yards, with most groups holding at 11⁄2 inches and several sub 1-inch clusters in the mix. Verify range and wind, aim a foot high of the boiler room and you are having venison for supper for the next few months. However, with the much larger .458 SOCOM, rounds "single stack" without any modification to the standard GI magazine feed lips or follower. It’s one hell of a hog hammer, that’s for sure. Both Starline and CorBon assure me that supplies should increase by the time this goes to press. Outstanding marine fishing is available from coastal piers. For long range shooting, 6-inches or more would be ideal. That's a tall order. The final case design has base and rim dimensions identical to the .425 Westley Richards, although making .458 SOCOM cases from it is impractical due to the high cost of .425 brass. This material may not be published, broadcast, rewritten or redistributed. It's an odd set of dimensions, but, as we will see, an extremely clever design for its purpose. That puts it squarely in the territory of the modern .45-70 or .450 Marlin, and it will do anything those rounds will do. © Copyright 2020 Military.com. It's a size and timing thing. You get the TAC-15. Read an account about a wolf hunt in the wilds of Ontario -- at temperatures as low as 25 below zero. Stay tuned. “So, the primary reason for the .458 HAM’R was to achieve more velocity and a flatter trajectory and longer-range bullet expansion.” The.458 SOCOM uses 200gr to 600gr bullets, with 250gr, 300gr, and 350gr being the most common. What does all this have to do with the .458 SOCOM? 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. That's not the way things are in the real world. 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 Rock River line is known for quality, and this rifle is no exception. They must be loaded to a narrow pressure. Range Conversely, one of the biggest arguments against the .458 SOCOM is its limited range. The .458 SOCOM loads into a standard double-stack 5.56 NATO 30-round mag, but it only holds nine rounds of .458. The pressure and burn rate must also be close to that of the .223 or timing goes to pot, you tear things up, and reliability suffers. The 450 Bushmaster uses a 250 grain bullet at 2200 ft sec for 2686 ft/lbs of energy( No The 300-grain (19 g) round offers a supersonic muzzle velocity of 1,900 ft/s (580 m/s) and 2,405 ft⋅lbf (3,261 J), similar to a … The Beowulf uses 325 and 400 grain bullets at 1950 ft/sec and 1800ft/sec. I am not surprised.

A lot of powder room was left in that case. 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. Marty ter Weeme, founder of a company called Teppo Jutsu, L.L.C., went to work. Best Reviews What Size Is The Bullet In A 338 Lapua Mag And 458 Socom Effective R 458 Socom VS 4570 GOVT - How Many Paper Plates??? . … It was shown as effective in terms of ballistics, firing a 500 grain bullet subsonically, but not ideally suited for its role due to the size and weight of the platform. Assuming normal optics/sights then the 458 is 300yrds. As of now, they only offer a 16-inch chrome barrel with a flash hider (good to protect the crown, even if you're not concerned about flash), and no front sight. Where I hunt with it, in central Wisconsin, long range is under 100 yards. With those weights, you don't have enough powder capacity in the .458. Normal to me means having enough elevation in a scope to reach the intended range without any shimmed bases. Parts need to be changed to make them function. They are made by Starline and available from them, Midway or Graf & Sons, but due to a fast-rising demand and the general shortages we've experienced since the last election, there are currently brass shortages, and orders are going on backorder. The recent rush of short and super-short cases that followed the .300 RUM are a perfect example of this, as are the .444 Marlin, .338 Federal along with many others. 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. This power is truly suitable for larger game, like boars and bears. The Socom shoots the largest bullets, 300,500 at 200ft/sec and 1300 ft/sec and a subsonic 600grain bullet. Prompted by the lack of power offered by the 5.56 NATO cartridge used in the M4 carbine and the M16 rifle, the .458 SOCOM came about from informal discussion of members of the special operations command, specifically Task Force Ranger's experience that multiple shots were required to incapacitate members of the opposing force in Mogadishu during Operation Gothic Serpent. The end result is a bit of an odd-looking case, but one that accomplishes all the goals. Velocity drops fast, and they slow way down and go subsonic, precisely as the design required. A standard 20-round 5.56mm NATO magazine can hold seven .458 SOCOM rounds and a standard 30-round 5.56mm NATO magazine can hold ten .458 SOCOM rounds. Just get a .458 upper available from Rock River Arms, Teppo Jutsu, or other custom builders, get loaded ammo from SBR Ammunition, Corbon, or Reeds and go. Following in the.45-70’s hallowed footsteps, the.458 SOCOM slowly achieved recognition as an effective cartridge against heavy beasts like bears and even the heavyweight Russian boars. [2] In 2009, Barnes developed a new bullet specifically for use in the .458 SOCOM, the 300 grain Tipped Triple Shock X, also known as the TTSX or TAC-X. Shop for cheap price Common 458 Socom Barrel Threads And What Is The Effective Range Of A 458 Socom . The mighty .458 Winchester Magnum only bumps 2,100 fps with the 300-grainers. The HAM'R has the same retained energy at 200 yards that the SOCOM has at 125 yards." Occasionally they hit a home run, and the likes of the .22-250, .257 Roberts, 6.5x284, or .224 TTH are born. At the time, the .499 LWR cartridge was still in development phase and had not been chambered commercially. The .223 magazine only hold three rounds of .458, making it legal for hunting where magazines are limited to five rounds or less. A wide diversity of powders have also proven accurate in the SOCOM from Hodgdon's Lil Gun to 4198. During the development phase, various other cartridges were considered and proposed to the project sponsor, but rejected as not meeting all the requirements. On the other hand, I hope this reviews about it What Diameter Are 458 Socom And 9mm Effective Range will be useful. Budget. They put out a request for a set of specs they want, and arsenals and commercial manufacturers go into high gear until the round is created. It's not just a hunt, it's like a night combat mission -- except the target doesn't shoot back. The case length was chosen to be compatible with the Barnes 300-grain X Spitzer bullet. This included the buffer, buffer spring, NATO magazines, many aftermarket .223/5.56 magazines, and magazine well. . 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. 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. In short, a short, fat case (1.575) with a very small rebated rim (.473), minimal taper, and a slight shoulder. You can make a fatter case work, but you can't be very much longer. This AR design likes this load. 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. All this ensures optimum accuracy while the long barrel ensures those who prefer to stretch the .458 SOCOM to its range limits will be happy to attach their most complementary accessories. The one component that is currently in short supply is cases. Dies are available from Hornady, Lee, CH, and soon will be available from Redding. There is the .458 Socom, the 450 Bushmaster and the 50 Beowulf. The .50 AE and .499 LWR were ruled out because in 2000 only two bullets were offered in .501 diameter, both developed as pistol bullets for the .50 AE and not heavy enough for the subsonic suppressed role. Because of the small size of the AR-15 action and receiver area, and the timing of the bolt cycle rate, you can't really use cartridges much longer in overall length than the .223 (a max of 2.26 inches OL). Cheap prices on all 458 Socom ammo. Whatever your preference, bullets won't be a problem, nor will the large pistol primers this case uses. The 300-grain (19 g) round offers a supersonic muzzle velocity of 1,900 ft/s (580 m/s) and 2,405 ft⋅lbf (3,261 J),[1] similar to a light .45-70 but with a much smaller case. .458 SOCOM AR-15 "HOGZILLA" -Interview + Shooting - YouTube 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.
