Can I Shoot a 458 Socom Out of an Ar15 That Is Chambered for Multi
March 27, 2018
In addition to existence arguably the most authoritative rifle design of its 52 years, the AR-15 is also the most controversial. Accordant to many another shooters, its alleged weaknesses fore from the cartridge it chambers. For the better theatrical role of its life, the M16/AR-15 digested only one kind of ammunition: the twin cartridges labeled 5.56 NATO and .223 Remington.
Currently, the 5.56/.223 is still the most concrete choice for the Atomic number 18-15. Even so, a myriad of other AR-15-special cartridges of more-or-less usable design have cropped up in the last decade or two, including the .300 AAC Blackout (SAAMI-approved in 2011); the 6.8 Remington SPC (2004); the 6.5 Grendel (2003); .25-45 Sharps (2014); the .458 SOCOM (2001); .50 Beowulf (2003); and the spanking-new .22 Nosler (2017).
In addition, wildcat cartridges for the AR-15, such as the 6mm/.223, abound. Even so, they'Ra not readily available, so for the purpose of this clause, we'll stick with SAAMI-sanctioned factory rounds.
What's the motivating behind all this cartridge origination?
Most frequently, new-cartridge designers signalize real and perceived weaknesses in current cartridges (usually the 5.56/.223) and make sometimes practical, sometimes outrageous claims as to how their new cartridge overcomes those weaknesses. My attribute favorite was Remington's statement that its new .30 Remington AR cartridge (introduced in 2008) was the ballistic equal to the .308 Winchester — and to prove it, the company provided ballistic charts contrasting the new short, thick AR cartridge with its 125-grain Reduced Recoil .308 burden. Clearly, the last mentioned does non showcase the .308 at its best; shooters byword through the forcemeat, and the .30 Remington AR — rather a able cartridge on its have terms — failed.
While most of the "recent and landscaped" AR-15 cartridges offer certain advantages over the original M16/Arkansas-15 round, well-nig one are inferior variable. E.g., the .300 AAC Blackout (which is bu a slimly modified edition of J.D. Jones's .300 Whisper wildcat) provides distinctly more close-range sureness than the 5.56/.223 and is particularly useful in suppressed firearms, only it waterfall divided at lank range.
Be that as information technology May, AR-15 enthusiasts have choices, and that's a dishy matter.
Here's a look at what I look at to be the quint most useful AR-15 cartridges available today, along with a brief grocery list of necessary conversion parts for each.
In full disclosure, I've left unconscious the big-drill hole thumpers such as the interesting .50 Beowulf and .458 SOCOM. Simply put, they're thus specialized that they're a little beyond practical.
Also — and I can hear the wails of skepticism — you'll billet that the 6.8 SPC magazine International Relations and Security Network't included. Why? It offers functioning so indifferent in all category that it's uninteresting to me. Information technology's non good at long-wooled ambit because it can't fool high-BC bullets, it's not good for hunting because it tin't buck bullets with adequate sectional density immoral enough, it's not good for competitive use because truth isn't particularly limited and wince is a bit high for fast work, and IT's not as authoritative at moderate distances A some of the others detailed here. Worse, unless unmatched is able to obtain ammunition loaded to the zesty pressure levels in the first place publicised by designers, performance is less than Ho-hum.
I can hear your gnashing teeth already. If I left out your favourite, well, cowboy up and essay one of these realistic AR-15 cartridges. And yes, the 5.56/.223 archetype M16 cartridge is one and only of them.
Crataegus oxycantha also protrude at the top, outside? Debatably, the 6.5 Grendel is the only magazine that can challenge the 5.56 for the rubric of AR-15 versatility champ. And if it weren't for the immense variety of dynamical choices available for the 5.56, it wouldn't symmetrical be in the same arena as the 6.5 Grendel.
Organized by Bill Alexander and cohorts, the 6.5 Grendel uses the .220 Russian as its parent case. If that raised your eyebrows, screw 'em back down before anybody notices — the .220 Russian is likewise the raise case for the world-title-taking PPC family of benchrest cartridges.
Accordant to Hornady's 9th Edition of Pickup Reloading, the 6.5 Grendel "...is quite possibly the almost efficient cartridge ever to be divided in the AR platform." Quite a resounding accolade from a company that created the most popular 6.5mm cartridge in history (the 6.5 Creedmoor).
My personal 6.5 Grendel is an 18-inch Hunter model by Alexander Arms with a side charging handle, and IT pushes a 123-granulate Hornady A-Easy lay at a rather pedestrian-sounding 2,440 feet per second (FPS). Nonetheless, the projectile is smooth enough (its BC is .510) that IT corset supersonic to 1,000 yards, even in the dense atmospheric conditions encountered at sea level, giving it genuine lifelong-range capability. Push that same projectile to 2,580 fps out of a 22- or 24-inch barrel, and it's flush better.
For big secret plan such as deer, antelope and all but giant black bears, handload a 120-grain Nosler Partition or Swift A-Frame to the same speed. Inside of 300 yards — or even 400 in the hands of a identical good rifleman — the 6.5 Grendel is a high-capacity venison hammer that offers follow-prepared shots faster than any bolt fulfill.
Predators? Its only weakness along varmints of the canine persuasion is the lack of same high muzzle velocity, which means that the 6.5 Grendel doesn't have the optical maser-flat short-terminal figure flight (inside 300 yards) of a .224 bullet going 3,200 Federal Protective Service. However, a 95-grain Hornady V-Max or Nosler Ballistic Tip pushed to 2,700 fps absolutely flattens coyotes and foxes; you'll just ask to cognize your trajectory and perhaps carry a rangefinder.
Happening the submit of altissimo speed, this new hot-retinal rod .224 magazine pushes varmint bullets really fast so — up to 3,500 fps with 55-caryopsis versions. Nope, that's not quite as fast as the .204 Ruger with 32-ingrain bullets OR the .17 Remington with 20-grain bullets, but neither does it have the will-o-the-wisp characteristics in the wind that plague those cartridges.
Better yet, the .22 Nosler pushes a 77-granulate Sierra Tipped MatchKing slug at 3,100 fps, and with its relatively degraded 1:8-inch twist rifling, information technology stabilizes them attractively. My handload averages .47-edge three-shot groups at 100 yards. Piece specialness 5.56 loads accomplish honest 1,000-yard capability, the .22 Nosler makes shooting 1,000 yards with an AR-15 almost a cakewalk.
In local atmospherical conditions near my home (5,050 feet EL, 50 degrees Fahrenheit and so Forth River), that speedy 77-grain TMK stays supersonic to on the dot 1,300 yards. This is an amazing effort for an AR-15 cartridge.
To the storm of many shooters, engineers chose to employ an entirely new cartridge case when developing the .22 Nosler. Use of a rebated rim enabled designers to utilize criterional 5.56 bolts, and a fairly steep 30-degree shoulder maximizes capacity without compromising dependability.
Two loads are ab initio gettable from Nosler: a 55-grain varmint and predatory animal load and a 77-grain Custom Rivalry load. I suspect that eventually we'll see a Partition surgery Bonded Solid Base bullet for deer-size game.
American Samoa for magazines, here's where the woeful 6.8 SPC (tongue in brass, folks!) actually contributed to the future of great AR-15 cartridges: Magazines manufactured for the 6.8 SPC are perfect for the .22 Nosler.
Without a doubt the second-nigh-popular AR-15 cartridge presently available, the .300 AAC Blackout also possesses the distinction of being remarkably focused. American Samoa in, not skilled. However, the unequalled advantages of the cartridge make IT both critically important within the Arkansas-15 realm and eyeball-bulgingly amusive for those who give it its due.
Piece its first appearance in wildcat form is rightly attributed to J.D. Mother Jones, the .300 BLK (official Saam short moniker) was refined for the AR-15 around 2010 and was intended to ply performance characteristics same to it of Russian Federation's legendary 7.62x39 fighting magazine. According to SIG Sauer's Trick Hollister, the .300 AAC Blackout was optimized for maximum efficiency in a 9-inch gun barrel, making it admirably well-suited for clandestine work in compact Ar-15 SBRs.
The nurture case is officially the .221 Fireball, and its ancestry harks back to the .222 "Triple Deuce," predating the 5.56/.223. However, in common terms, the case can be thought of as a varied .223 case necked up to bear .308-diam projectiles and trimmed to a much shorter 1.378 inches.
As a issue, the .300 BLK functions utterly with standard AR-15 bolts, magazines and everything else. All you take is a new drum.
Most mill scores for the .300 BLK feature either a very light or a very heavy 30-calibre dynamic. Harsh versions are crocked to subsonic speeds, which get into't disturb the sonic barrier and create the clearly audible sonic crack; in other words, when paired with a quality suppressor, the cartridge hindquarters be very quiet indeed. Typically, subsonic .300 BLK loads push match bullets of 200 grains or more, and while they'atomic number 75 the essence of AR-15 subtlety, they have limited wont at anything beyond uncommunicative range.
The lighter loads utilize 90- to 125-food grain bullets and achieve around 2,200 to 2,600 fps. Obviously, suppressing these ISN't nearly as effective American Samoa suppressing subsonic projectiles, but they'Re still not obscenely trumpet-like since they don't burn much propellant. Generated muzzle energy ranks from 1,300 to 1,500 foot-pounds, just a few percent short of that provided by the 7.62x39. Plus, although the aerodynamics of the short, fat projectiles is abysmal, inside of 200 yards OR then they provide really available fighting-grade ballistic trajectory.
Admittedly, including this magazine was a bit of a gamble. It's not peculiarly substantially-known, although it deserves to be, and it has not practiced the growth necessary to bring its full possible to fruition. That aforementioned, information technology's a superb bitty hunting cartridge that matches the then-spectacular performance of the classic .250-3000 Savage cartridge. Introduced in 1915, the .250-3000 was the start magazine to achieve 3,000 fps gag velocity, and at the prison term it was the cervid cartridge to have.
In design, the .25-45 Sharps is simply a .223 pickup case necked capable 25 caliber. In fact, it's basically a easy and legitimized version of the .25-223 wildcat, which is the same thing with the case shortened .050 of an inch to allow the role of longer-nose cone 25-caliber projectiles. According to designer Jay Lesser, he and his team at Sharps Rifle Party engineered it that way to make forming .25-45 Sharps cases from .223 organisation as easy arsenic contingent. Plus, shooters with a supply of .25-223 brass can safely evoke IT in their .25-45 Sharps chamber.
The likes of the .250 Savage, the .25-45 Sharps testament push an 87-cereal soft-distributor point bullet to 3,000 fps out of a 24-inch cask, giving IT legitimate authority on cervid-apple-sized game. Lighter bullets in the 70-grain browse throne be pushed to 3,200 fps, offering solemn predator-thumping ability. My favorite handload features an 80-grain Barnes TTSX bullet at 2,925 fps; the tough projectile penetrates better than factory-inebriated bullets and groups to a lesser degree ¾ MOA.
Because it is best suited with light-for-caliber .257-diameter bullets, and .257 bullets don't have the superior aerodynamics to begin with, the .25-45 Sharps isn't big at long orbit. But IT's good for deer and small halt, it's easy and economic to reload, and it offers about 10 percent more muzzle energy than the 7.62x39mm — which is famous as a manstopper.
Ah … the all-around champion. Because the barbed forces have been stuck with the 5.56 NATO cartridge for concluded a half-C, special R&D teams inside and outside the military have made a betoken of nonindustrial performance-enhancing loads. As a result, the cartridge has become far more capable under a large set out of demands than anyone fighting in the jungles of Vietnam could have imagined.
Nontoxic projectiles? No job. Penetrators? Sure. Low-flash self-defense lawyers ammo? Absolutely. Long-range, 1,000-yard-capable ammunition? Right this way. From speedy featherweight projectiles screaming out of the muzzle in extra of 4,000 fps to heavy, and then-long-you-let-to-single-load bullets intentional for maximum range, ammo for the 5.56/.223 runs the whole gamut.
Purely because of the almost limitless versatility of available ammo, the 5.56/.223 is still the practicality champ when it comes to AR-15 cartridges.
Because I don't have nearly enough room to talk over all the various genres of 5.56/.223 ammo, let's just take a brief look at a few of my favorites.
On the lighter position, Hornady's 40-grain V-Liquid ecstasy load usually shoots lewdly tiny groups even in the faster 1:8-convolute ARs and achieves someplace faithful to 3,800 Federal Protective Service. As a result, IT's unpolluted poison on predators.
Jump dormy to a medium-weight rocket, I've had tremendous circumstances with Hornady's 60-grain V-Scoop in footing of accuracy. Almost every Atomic number 18-15 I've fired it through shoots information technology into sub-1-inch groups, even those that aren't well-stacked for truth. Plus, IT fragments violently on impact, qualification it ideal for personal aegis in densely populated urban environments where you really want bullets to stop in a violent scourge's body surgery — heaven forbid you miss — fragment in the wall instead of going done and endangering your neighbors.
Each that said, though, my two all-time favorite loads for all-around bring up from zero to 1,000 yards are Barnes' 85-grain Precision Match, which is a wonderfully accurate load that I've North Korean won many an competition with, and Black Hills' 77-grain Filter-tipped MatchKing .556 load. Some execute admirably to 1,000 yards, expand dramatically in ballistic gelatin and shoot with eyebrow-raising consistency. Amazingly, the Barnes loading is inaudible to 1,090 yards, and the Black Hills load to 1,120 yards in my local atmospherics, giving both versions real-world, long effectiveness.
While they're non as debauched and flat wrong of 300 yards, making it slightly more difficult to connect with a coyote, I know on that point's nary take exception privileged of 1,000 yards that I arse't at to the lowest degree make a credible attempt at meeting. And that, my friends, is versatility.
