      Sure it can kill, but it wont be a "humane" kill. For example hunting hogs a 110 VMAX will do much better than a 220grn sub. Not to mention humans and body armor, although 300 sucks in general against armor.

        It was designed specifically for the niche of suppressed subsonic fire out of an AR, for spooky operators to poke holes in people at close range. It's literally just bacon flavored 9x39mm. Whether a kill is "humane" matters to hunters, not the fucking SEALs.

          So youre telling me the guys who kick in doors, and very well may encounter people with armor are willing to use a fucking subsonic round that cant defeat soft armor much less LV3+?

            The entire purpose of .300 BLK is for the theoretical situation where you're some super secret squirrel operator who needs a suppressed subsonic gun (which will always come at the disadvantage of having handgun tier ballistics), but at moments notice you could also be involved in a normal firefight at which point you'd want normal supersonic rifle ammunition. There's basically no reason to go for it as a civilian, and most of the people who do go for it don't have a suitable sighting system that either offers both zeros for super and subsonic ammo, or can quickly swap between the two.

            Supersonic doesnt penetrate hard armor either. So the only thing you loose out on is penetration of soft armor and helmets. Pelvic and face shots are quite lethal, so if you're really worried about soft armor, either shoot them in the neck/face or the pelvis. Or load supersonics

        This is kinda wrong but I must respond so that less learned lurkers can understand. What is good for a conventional military force is not necessarily good for individual/asymmetrical force users. 7.62x39 is a great cartridge much better than .300 blackout for overall usage but not as good as 556 for conventional forces because the meta is volume of fire until artillery/airforce. You can just carry more 556 so it works better, hence 5.45 development. As a civilian you would be better served by 7.62x39 or .308 than either of the other cartridges except in terms of ammo availability for 556

          flat trajectory and higher bullet velocity generally means greater likelihood of a hit at range and more likelihood to hit a moving target without significant correction
          7.62x39 is a dramatic shift from 556 and it's not a huge surprise that Russia began looking into a high velocity cartridge about 5 years into the Vietnam conflict.

            Can you read what you just wrote. The Vietnam war was a jungle battle which 7.62x39 is a superior round for it due to less deflection in brush and lower ranges. Vietnam would not be the deciding factor in changing their cartridge. Preparing for peer to peer warfare would be the reason, it was the cold war but they were worried about hot war the whole time. You may be correct about the trajectories and range but you are missing the whole point of this thread and my last response. In a military scenario 556 and .300 can be issued based on usage and would fill their niche better than 7.62x39. Ultimately as a civilian/guerilla force 7.62x39 is a more versatile cartridge that can get away with lower volume of fire and less artillery due to different tactics and equipment availability vs 556. It can also fill the shoes of .300 blackout very easily with a mag change in a well built modernized AK (which is basically the only platform let's be honest).

        ...aside from your timeline being fucked, the vast majority of the Warsaw Pact didn't adopt the 5.45 despite having a massive incentive to do so. Neither did Finland nor China. After the Fall of Communism most of them went to 5.56 for political/NATO concerns, not because of any massive leap in performance. China went to their own propritary cartridge and several other nations that adopted 7.62x39 kept it, going so far as to adopt modernized rifles in the cartridge.

        It doesn't make sense to switch from one intermediate cartridge to another unless you have money to burn or allied logistics to worry about.

        5.45x39 began development at the very end of the 1960s

        And it wasn't formally adopted until 1974, at which point the vast majority of guns in Soviet service were still in 7.62x39. That's at least a 30 year service history, which is very respectible.

    It does this better than most intermediate rounds. .300 BLK gets zero flash with a suppressor where 5.56 is pretty notable.
    >close range energy
    Not extremely useful on its own, but very nice when compounded with its performance in a short barrel. An 8" .300 BLK has as much energy as a 14" 5.56. That means you can have a suppressed gun that's just as long and powerful as a non-suppressed 5.56 version.

    300blk is cool because it's just a PCC with added options. Can get a gun smaller than an mp5, that's effective out to 200+yards and is more lethal.

    The real comparison is against .350 legend. It is more powerful, not meaningfully more expensive, throws a heavier subsonic bullet and has more muzzle energy in supersonics. Also bullet starts bigger and has more expansion potential.
    Also it's more retard proof by not being chamberable in a 5.56.

      I wish .350 legend were better designed. .355 bullets instead of .358 is a turn off, as is the rebated rim, as is the lack of a parent case, as is the horrible marketing by Winchester, (trying to dethrone .30-30 with bullshit numbers? Good God!) as is its dumbass name. It's still better than .300 blk though.

      >made for bitch states when it comes to hunting
      >barely exists
      >terrible bc because lol flat nose bullets

      I'm tired of this memetastic horseshit. Both the cartridge and firearms chambered for it are sold by multiple manufacturers, at affordable prices. State restrictions on caliber work in its favor, not detriment. "Lol flat bullets" is a non-concern as .357 magnum has repeatedly taken all forms of American game, including brown bears, from fucking handguns. .350 Legend extends that range to 200 yards at the absolute minimum. And, you know, spitzer .350 legend exists.

      .300 blk only really beats it at extended range, but it's then destroyed by 5.56 unless you're comparing subsonics. I'm completely uninterested in the long range potential of SBR's.

        Second worst criticism for two (and a half) reasons.
        1, you can get a sizing die and size down the .358 by 1 thousandth
        2, you would size yourself out of .355 diameter bullets which removes every 9mm loading, which probably outnumbers .358 offerings by a factor of at least 10,000 times.
        2.5, you have support for .350L specific bullets like 180 soft, 150 FTX, 160/5 ballistic tip, etc.

          The vast majority of which would be overdriven at .350 legend speeds, but I suppose there's something to be said for reduced loads. I've been curious to see what a monometal pistol bullet would do at that speed, I must confess.
          >Support for .350 legend bullets
          I mean, they could've just used bullets designed for .35 Remington. They're very close. Nothing would've precluded .350 legend specific bullets from being retrofitted back to .35 Remington either, for the 17 people who still use that cartridge.

            Yes, however the statement

            >5" barrel 556 would be pretty awful in terms of post-hit effects

            remains true for subsonic 300blk as well, and the rest would also remain true for supersonic 300 as well. The whole concept is about give and take. And sure a subsonic 5" 300 barrel would be WAY more quieter than an equivalent length 556. But then you run into "well a 9 inch 556 would have better terminal ballistics while not sacrificing much for OAL". Its just a series of justifying whatever your stance is. In my opinion there was no reason to keep the 300s hanging around. I am not kicking in doors shooting kids in a foreign country like oper8rs are doing so I do not see the need in a quiet 300 when my MP5SD was quieter than any of the 300 subs I shot.

    Keep in mind how .300BLK was conceived, which was just taking .300 Whisper and commercialising it. .300 Whisper was mostly designed for single shot applications that I know of (JD Jones loved his Contenders) and when handloading it's dirt cheap, and it's not as if you shoot a lot. Availability is stellar in that regard: you will always have .223 cases and .308 projectiles, if not, there's bigger issues. Yes, subsonics lose a lot of energy compared to supersonic rounds, but have a lot more energy than the subsonic alternative on the same bolt face (.223, .221).

    It's two guns in one. With supersonic ammo, it can work in the same role an AKM. With subsonic ammo and a suppressor, it can work in the same role as an suppressed SMG. AKMs are cool, and suppressed SMGs are cool, so a gun that can do the same job as both of these without requiring modifications is also pretty cool. Furthermore, all of this comes in a very compact setup, that also uses AR parts and magazines, which are easy to access compared to other guns.

    The biggest downside is cost: to get the most out of the round you need supersonic and subsonic ammo, and an SBR and suppressor. Braces have solves the SBR issue for most people, but suppressors are still costly and need to be registered. But if you can afford it, it's a very interesting and versatile round.
