.458 Socom Full-Auto – Expensive & Awesome

While I have never shot the .458, I find it alluring as a big-bore cartridge. Quickly gaining a following within the MSR market, the cartridge balances a wide range of capabilities and bullet weights to create a versatile package.Unfortunately, this growth in popularity has stretched its manufacturing base, with many loadings and parts difficult to find.

This makes GY6’s video either a treat or a horror, depending on your desire to shoot the ammo. Andrew goes full-auto with the big-bore and enjoys it. Slotted for destruction include pumpkins, meat, and includes a ballistics gel hit.

    For $3 a round, I think I’d prefer .50 BMG. Either way, I’ll have to stick to the “lowly” 5.56 since the kids keep needing this thing called “food”…..kids these days.

    • B.K.

      You have your priorities all mixed up ; ) They run $3 a round? Ouch! What does the modern .50 equivalent go for? I have a handful of them leftover from shooting with my uncle from a few years ago.

      • TheNotoriousIUD

        About $5 a pop.
        That’s why mine has dust all over it (metaphorically).

        • B.K.

          Wow, I honestly had no idea there that costly. I don’t blame you. Is the military just stocked to the brim with old stockpiles of 50bmg? I thought I remember my friend saying the stuff looked 50-60 years old.

          • iksnilol

            .50 BMG is used in MGs and is used by entire NATO. Of course you can it (relatively) cheap.

          • TheNotoriousIUD

            Dont ask me I just know its off the charts.
            Or it was I should say since I havent even bothered to look for a few months.

    • noob

      Cooking. It’s like handloading food, except more expensive.

  • B.K.

    Simply awesome! Those visuals are incredible. If placed in the situation that round looks absolutely brutal. I know it’s a pumpkin and some gel but WOW!

  • STW

    A friend of mine shoots both the .50 BMG and the .458 SOCOM and, last I checked, had several hundred rounds of .50 BMG. Being a heart surgeon leaves him able to pay for lots of stuff for me to look at. (We’re BBQ cooking friends not shooting friends)

      @ STW.

      Your comparing Apple’s with Orange’s. the .50 BMG (13×99) with a .458 Socom (11.63×40), the .50 BMG is a Very Long Range Projectile. While the .458 Socom is a “Show Stopper”, 500-meters or Less…

    That may just over penetrate a bit, I’d like to see some drywall or something behind it. I have no experience with the round, but always wondered what it would be like as an entry round. Having what appears to be a MFT minimalist stock on the FA lower may not have helped with recoil.

    • Arnold_Laine

      My non-expert opinion. gleaned from what others have written about various rounds and over penetration, is that .458 would be one of the worst choices if thats a concern. Heavy, slow moving rounds are generally the ones that go though lots and lots of drywall.

  • Jeff Heeszel

    The kick is about the same as shooting a 12ga slug. The lightweight AR platform means a lot of the recoil goes to your shoulder. If you are going to get into shooting this round, your best bet is to reload yourself. Still the bullets alone are about a buck each. It isn’t a round that is enjoyable to shoot very much, IMHO.

    • cawpin

      The recoil is not as much as a 12 gauge slug.

  • Limousine Liberal

    Great gun for taking down a whole heard of elephants?

    • Secundius

      @ Limousine Liberal.

      From WHAT DISTANCE? A Elephant can reach a speed of 10-meters/second when charging. If there are More of THEM then ammo load your carrying YOUR DEAD…

  • smartacus

    Did you see what happened to that ham?
    a hit to a femur would cause instant drop in blood pressure and instant drop to the ground as if it were a head shot.

    “Unfortunately, this growth in popularity has stretched its manufacturing base, with many loadings and parts difficult to find.”

    Please don’t forget to mention that there are several companies offering items labeled as “.458 Socom” that are reverse engineered, and non-licensed, and have had notable problems. For rifles and parts, stick to RRA, SBR and Tromix, with Tromix being the best choice.

    • AK™

      What about Wilson Combat? They sell .458 complete uppers for $1,350..

      • cawpin

        Nope, not licensed. I wouldn’t buy one from them. Way too expensive anyway.

  • Secundius

    There’s a Company called McCann Industries. That Makes a M1 Garand version in .458WinMag. Like the .50 Beowulf, the .458WinMag. is range limited to around ~250-meters Effective Range and ~500-meters Maximum Range. It’s a “Last Ditch” Round…

    • sauerquint

      458 Socom and 458 Win Mag are completely different, the only thing they share is the bore size.

  • Markbo

    Does anyone responding even have a .458? I do. Ammo doesn’t have to be $3 per round. If you reload like I do, it is even less. Way less. The thing is, there are lots and lots and lots of bullet choices in .458 that allow you to shoot anything from 140gr to 500gr. They do not HAVE to be that destructive. It is a supreme hog and even deer gun – with the right bullet. This is not a .223 and isn’t meant to be a long range round or a plinker where you go shoot 200 or 300 rounds at a time. Pick a bullet for your game, sight it in and shoot once. I have never shot anything that needed a second round. I would probably limit my shooting to 150-175 yards. When you can put .50 BMG in an AR15 sized package, give me a call. Until then you are so missing the point of the .458 SOCOM. And this Marine needs to learn how to shoot. Missing a gelatin block TWICE at 20 feet should embarrass the crap out of him, whatever is sight excuse is!

  • noob

    this needs to be incorporated into some kind of action movie.

    Why on Earth, would you need a Fully-Automatic .458 Socom (11.63×40). If you can’t HIT the Target at 200-meters in ONE-round. What would FOURTEEN-rounds, plus ONE At Full Auto Accomplish
