    it doesn't go through lvl3A, so its just a oversized 45 acp?

      If you use subsonics, sure. If you use full power rounds they're closer to 7.62x39 in performance. It has a flatter trajectory, too.

      Really short carbines.

      With subsonics, maybe, but you can load heavier projectiles if you really want to.

      Pretty similar to .30-30/7.62x39mm ballistically if using supers so it's a decent hunting caliber for medium game.

      .30-30 Winchester is a good bit more powerful than 7.62x39mm and .300BLK

      Yes, less blast, better terminal ballistics inside 150m in general(particularly post barrier), and better performance specifically from short barrels. Honestly it's better than 5.56 for realistic defensive use and most intermediate caliber hunting use as well(ignoring the 200-400m TMK/ELD crowd). Only negative is cost on practice ammo.
      >Muh velocity
      Mass and frontal are matter a lot too. Just compare the field results between quality supersonic .300 blk loads and 5.56 ones. Better effect on target, deeper penetration, bigger wound cavities, bigger exits and better blood trails.

      Even with subs it can penetrate at least some non special threat vests some of the time. 200gr + pointy bullets can be hard for kevlar to stop. Somebody should really make some extra pointy work hardened copper subs for science(may fort Scott already does?)

    It's best selling point is use with a suppressor no doubt, but it does much better with a really short barrel than 5.56/.223, making it nice for SBRs or PDWs. Unironically outclasses SMGs except for the most specific roles.

      the issue i think is if you are running subs with suppressors, and you move to supers, it is super overgassed even with adj gas block. The alternative is that it won't run without suppressors with subs

        That's not even close to true. I can swap between suppressed subs and supes, and unsuppressed with zero change in reliability. I do however need to adjust my zero for each type, so it's best to take notes and scribe optic turrets if switching often. Btw this is a 9" SBR with a basic bitch DI.

    Not really, and it doesn't do that as well as 350 legend.

      Has ANYONE tested any .350 against any armor?

    100+gr bullets under .30" typically make it out the opposite sides of animals that cup and core .22s won't. Is that relevant to most of the guys running 7' .300blk uppers with stupidly high twist rates? Probably not. Pen over 18" doesn't mean fuck all for people planning on killing other people.

    Seems to work well if you wanted to scuttle your 5.56 rifle before capture

      Unironically point me towards a magazine fed automatic chambered for 11mm Gras which is readily available.

      on anon. try finding 7.62x39 subs for cheaper than a buck a round, for fucking brown bear.

        what do the current economics have to do with the fact they're nearly identical ballistically?

        find a more entertaining way of telling me you're poor and stupid next time

          my point is availability. there are two whole brands to choose from and both are clearly not produced in large quantities. also long-strong gas piston guns are worthless for suppression.

      >.300BLK fits in a .223 magwell and action so you can have it in a good gun like an AR15
      >.300BLK actually cycles with subsonics which standard AKs in 7.62x39mm won't
      >there's better options for .308 caliber projectiles
      >there's better options in general for .300BLK ammunition
      But go on and settle for your steelcased poorfag specials, and enjoy those cold bore 4MOA groups.

    .300 black and 7.62x39 perform very well from shorter barrels. If you're going the sbr route/anything shoter than 12'5 these are the calibers are the bees knees

    I can reload with spent 556 brass and 308 projectiles, which is really quite nice.
    Both are hilariously common, so it's really cost effective.

    .300 BLK is good for suppression. 7.62x39 is better for going loud. if you want a gun for doing suppressed operations, I would go with .458 SOCOM rather than .300 BLK.

    I think 300blk is one of those calibers you really need to be a reloader to appreciate, because you can get a whole bunch of .223 brass and reload .223 or 300blk with it as you see fit, using the same 30cal bullets you'd use for your other 30cal shit, you can get the exact velocities you want for whatever you're doing with it, and you can keep costs down. But buying 300blk off the shelf sucks and adds more costs to the already steep costs of needing to get multiple tax stamps and possibly even multiple uppers with multiple optics to really get the most out of the caliber.
