lmao you're basically shooting a glorified pistol bullet

    I don't get it. Everyone knows 300blk subsonic is around the same grain and speed as 45acp, which is still notably more energy than 9mm subsonic. Of course cucking supersonic cartidges to under 1100 fps is going to fuck their energy. The same is true for subsonic 5.56, which might as well just be 22lr.
    At least 300blk has the benefit of being able to run both subsonic and supersonic out of the same 8-9" barrel and still get near optimal performance with both.

        I don't actually own one myself. I've heard that many need suppressors attached to cycle subsonic properly, or at least claim that for warranty reasons. Most seem to be around 8" and 1:7, which is ideal for subsonic. That might be too much twist for the lighter supers, but I doubt it's enough to matter. 1:7 16" 5.56 uppers are common now and nobody complains about them.

        It's actually super easy to do.
        The really short ones (7.5") aren't as viable across a wide range of cartridges and weights reliably without the increased pressure from a suppressor, but if you get a 9" or 10" that still has a pistol length gas port you can run pretty much whatever reliably.
        Either that, or open the gas port up to like draco port diameter and get an adjustable gas block like the riflespeed unit, then dial it in for whatever you're shooting.

        If you want instant incapacitation, you aim for the brain. Otherwise the muscles have enough oxygen stored that instant incapacitation is a coin flip even if you totally destroy the heart and lungs, unless the animal was running around before being shot.

          7-9 seconds. That's the time to bleed out and unconsciousness/death from a heart or major artery shot. A deer can and sometimes do cover a remarkable distance in that time. But usually if you pop a heart they drop right where you shoot them.

                They can't have been that skittish if they let our ancestors domesticate them. We hunted a lot of animals to extinction, too. Remember reading there used to be pigmy hippos in the islands near Greece but humans ate them all. Bet those little dudes were tasty.

                Yeah that’s my point. There were less skittish then. There were also way more of them. Or that’s what the original guy meant, I think.

                Tame made more sense to me, even though I'm not that Anon. I get that skittishness describes how nervous the animal is, but there's obviously the connotation that a skittish animal is quick to flee. Either way we both understood the same meaning. Maybe "oblivious" was a better word choice. I'd rather imagine those pygmy hippos were oblivious to the threat than the alternative that they were aware, but simply too small and slow to survive.

                Yeah skittish might not be the best word. We’re arguing over semantics and I think we agree on the main point. Animals thousands and thousands of years ago were more abundant and were easier to get close to and approach to hunt than today. Whether it’s temperament or obliviousness or just a higher raw number means more stupid ones exist, they didn’t act quite the same as today.

      Doesn't exist in the real world since the gun will be gassy as fuck and beating itself to death if it's tuned to run subs reliably which is will be because supersonic 300blk is just 7.62x39 at 4 times the cost.

      SOCOM figured this out thats why they went with dedicated suppressed uppers and now the pdw.

        A gun "beating itself to death" is a relative term. Lower service life (how much lower is the question) can be an acceptable trade off for this capability. It is perfectly possible to have a suppressed upper go from super to sub every other round and function flawlessly. Will the supers be over gassed? Probably, but by how much and is it enough to make a difference in long term wear? The AK platform is notoriously over gassed, as are carbine gas 16" AR's and both have acceptable wear standards when built with quality.

              That’s absolutely false. You have well over 400 ft lbs at 200 yards with most loads. Some have more than 300 ft lbs at even 400-500 yards. The trajectory at those distances make it unusable but that’s not what you said. In the intended range of 100-150 yards, maybe 200 yards they have 3-4x the energy of a .32.

              Even if you load something significantly weaker like a 180 grain Sierra Game King at 900 FPS, the bullet is still going to have more than 200 FPE until it reaches a bit over 800 yards. Fuck off retard.

      There's no point in owning 300blk if you don't have a suppressor for it. Suppressed subsonic sbr is the best home defense option available, objectively without debate. The supers that reach good velocity in a shorter barrel are just a bonus.

    I own a .300blk rifle and totally agree.
    That's why I only shoot supers through it.
    .300blk burns it's powder in the first 10 inches of barrel.
    It's better than 5.56 for SBR's but I would argue that it's better in general inside of 200 yards. Why 200 yards? Because that's the distance that it remains above the magic 2,000fps number and it does so while keeping more energy, momentum and cross section than 5.56. Past 200 yards, 5.56 takes back over, retaining true rifle velocities to a greater distance.

    So, if you carry .300blk supers in a supressed 16" rifle. You have a 2,400fps muzzle speed with more energy, mass and cross section than 5.56 in a round that still suppresses the muzzle blast very well. Yes there is a super sonic crack but there's no avoiding that with proper rifle ammo.

    I'm agreeing with you OP, subsonic rifle ammo is silly. Just use pistol ammo at that point.
