    I recognize that this is a slide thread because of the GT thumbnail and low effort OP question, but regardless I think it's effective. The main controversy is whether or not the added spin speed actually helps terminal performance as they claim. They did some shady stuff with gel tests to make their round look a bit flashier for the camera -- stuff like water splashed on the block, so some people dismiss it, but having seen other gel tests I'm quite impressed at how well the cavity follows the spin of the round. Additionally, I've seen barrel length tests that show that speed drops off very quickly with barrel length (peaking around 14 inches), likely because of the induced drag of the fast rifling. If their claim that rotational energy significantly impacts lethality is true, then it's simply leaving money on the table if your round doesn't also doesn't become slow as hell after a 16" barrel (or whatever length you consider to be most practical).

    Personally, that leads me to the conclusion that even if their claim about rotational energy translating to bigger temporary wound cavities and whatnot is wrong (which it may be), it seems pretty undeniable that higher rotational speed means the large blender-like petals of solid copper projectiles can carve more flesh or bone per square inch traveled. I would like to see how they perform with a cavitation based round like underwood offers and compare, see if there's any difference at all when it's fired from a fast twist barrel vs a slower twisted one.

    It feels like a marginal gain, but a gain nonetheless.

        If you’re confined to a subsonic projectile the only way you can make the round more lethal is to increase the mass of the bullet, spin it faster, and get the round to contact more tissue by designing the bullet to expand but stay together.

        I’d really like to see the 1 in 1 gel tests they say they have.

          man, if only there was a material more dense than copper we could make a bullet out of, or in part out of, which would raise its mass, and therefore it's muzzle energy at a given velocity.

        holy smokes, is this the best you can do? go ahead, get back to me with how much muzzle energy you gain going from 1:9 to 1:3 twist for a 300 gr bullet at 1050fps. I've done the math, but it's important to establish repeatability, and who knows, maybe I screwed up.

        >one of which have never, in the history of ballistics, been shown to increase any terminal performance in any way
        I don't believe any studies have been done specifically on solid copper projectiles that expand as the ones we have now do. If there isn't a large gap between the petals, rather a more uniform expansion as seen on traditional hollowpoints, then it would make sense if no additional damage is found.

        If there are such studies, I'd love to see them. However, all visual evidence I've seen from gel tests seem to indicate that the idea of a buzzsaw effect does have implications for wide expanding projectiles specifically. You can argue about the use of such projectiles and their validity compared to more uniform hollowpoints, but that's another argument entirely. I am skeptical about their claims on if it improves anything but that, but that alone has significant implications for subsonic rounds, which is why I suggested using lehigh bullets or something else to isolate for factors relating to metal geometry.

      To me, the interesting aspect of having such a short spin is minimizing barrel length. So you have 1 in 3 twist? why not make a rifle barrel that is there or four inches long? With extra hot hybrid case ammo?

                - the topic is the number of rotations the bullet must make in the barrel before it is actually stabilized. And the answer, as inspection of the stability equations quickly reveals, is utterly immaterial. Also, as a demonstration of this, snub nosed revolvers have no problems stabilizing their bullets despite having only an inch or so of barrel length and a twist rate of 1:16 - meaning the bullet only makes about 1/10th of a turn before leaving the barrel.

                Yep. It's something that can be either measured instrumentally or worked out with discrete calculus and an accurate specification for the bullet. If you're willing to get "good enough" then you can just use some generic stability factor for e.g. "jacketed lead core spitzer rifle bullet" or "hollow point pistol bullet" - that's what most of the twist rate calculators are doing.

            As long as the rifling twist rate is fast enough to stabilize the bullet at the muzzle velocity, it doesn't matter if the bullet makes 1, 2, or 20 turns inside the barrel. Look at a snub nose revolver, the bullet makes something like 1/10th of a revolution between the time it hits the forcing cone and the time its ass leaves the barrel. Stabilizes just fine.

        NTA, twist rate has nothing to do with barrel length. The spin is imparted instantly upon engraving and will always come out of the barrel spinning once every 3 inches. Even if the barrel were only an inch long.

      Came across it developing 300 blk (wanted more than 1:5, but that was the threshold for stabilizing both subs & supers). Permanent wound cavity comparisons are out there for review. It's doing with subs what I'd otherwise like 35 Whelan for, and even more with supers. Aids stabilization of the subs, farther as well.

      If you compare pictures of Maker Rex expanding bullets in 8.6 and other calibers, you’ll see the 1:3 twist rate has the effect of turning the petals 90 degrees along their axis, presenting a cutting edge in the direction of travel, and resisting folding back onto the shank. Net result is wider expansion AND higher SD while expanded. That’s pretty sick. Plus the bullet’s so stable it doesn’t tumble. In gel footage you can see the petals tracing (cutting) a helix throughout the entire length of the block. What I REALLY want to see is this idea taken to the extreme with ultra heavy .224 bullets. Like 120gr +, L:D of 7+, 1:2 twist, and with maximum expansion/terminal effect for minimal powder charge. Also would suppress much better than either of the blackouts. Can use a straight wall case like the 5.56 Knox. 100rd quad stacks the size of a regular PMAG.

      Anywho. To answer OPs question, I like spitzer thumpers, so I like 8.6 blackout. Besides that, A hybrid case ~100gr with low form factor would make a pretty cool neo-CETME round too. Doubt any bullet would hold up to 1:3 twist at ~3000fps though. Maybe with a slower twist.

        You understand mass and velocity but construction and material type impacts lethality. If the round was depleted uranium it would have great penetration but wouldn’t expand. If it were lead it would have more mass but would break apart due to the rotational rate. So the the mass is limited by what the desired expansion characteristics are.

            moron sperg, 458 has terrible magazine capacity and was therefore replaced with 300blk.

            Again, since you can’t figure this out, the whole point was to make a more lethal subsonic round.

            Since the limitation was subsonic speed, they had to increase the size of the bullet. The only place they could speed up the round was with rotation. They specifically constructed the bullet so it would expand but not break apart. It’s like getting shot with a crossbow bolt. They selected a round that would fit into an ar10 mag and run reliably. This combination makes the overall system lethal. It’s also quiet and performs well from a short barrel.

            The 350 can’t load into a pmag. The 300 is less lethal and getting a twist faster than 1 in 5 takes a custom barrel.

            Nothing on that chart outperforms 8.6

            I’m referring to expanding bullets. The sig rattler was limited to 1 in 5 so expanding bullets wouldn’t break apart. The 8.6 uses copper slugs to keep the bullets from breaking apart.

              .458 SOCOM, .450 Bushmaster, and .50 Beowulf are the general category of "big bore" for the AR-15 platform. .300 BLK doesn't "replace" any of them, even if you're referring to strictly subsonic loads. The only recent cartridge that could "replace" any of them is the .400 Legend. Which would also be better than the 8.6 BLK at being "fat and slow" simply by virtue of fitting in an AR-15.

            Energy is a wive's tale. Energy doesn't kill anything, punching hole in vital organs does. This is ensured by:
            1) Shot placement
            2) Projectile integrity
            3) Velocity at impact
            8.6 drifts less and drops less than 458, which aids shot placement.
            There are numerous 338 bullets that will zip through anything you might want to shoot them into without zooking up.
            As you can see in the charts, 8.6 arrives on target with higher velocity than 458 at all ranges.

              I'm sure you've run rigorously controlled scientific studies on terminal ballistics. but that doesn't surprise me, because neither has Q.

              this Black person did and velocity has nothing to do with it except as a component of momentum.
              also, if velocity and drop are so important, why not use a supersonic round, like .308? it has far better ballistics than subsonic .338 whisper.
              >8.6 drifts less and drops less
              how much? go ahead and say the numbers, because when I get a chance I'm going to measure the subsonic BC of those 576gr bullets and recompute the ballistics tables.
              just to prove a point, what do you think the BC of pic related is at 1000FPS? I measured it with my lab radar.

      458 socom is a moronic cartridge that has no justification for its existence. MUH ENERGY! Look how much of its starting energy it has lost by 500 yards. Look how much more drop it has. Look at that piss poor BC. The recoil is far too great for what it is, and mags hold like 7. Compare that to the 8.6’s flat energy curve, 25rd mags, and half the recoil.

        Still waiting for someone to tell me how much energy a 300gr solid brass bullet gains at 1050fps going from 1:9 to 1:3 twist.

          > which is exactly what every hollow point does, but this times it's a sales pitch so it matters more

          No, moron. My point is the bullet stays oriented in its direction of travel. The proof is the traced helix.. Regular hollow points do not do that.

          > man, that's crazy. what if we just used normal twist rates and bullet construction to achieve higher muzzle energies?

          No the 1 in 3 twist is good for <2000fps, was just thinking of what else the 8.6 could be given a low overbore ratio and super long ogive. Really all that’s standing in the way of a new CETME round is its twist rate. Superheavy subs, mid weight mid velocity whatever load, and ultralight intermediate cartridge. It could be 3 cartridges in 1

          Pretty sure the extra energy from 1:9 to 1:3 is negligible, I think someone here did the math a while back and came up with like single digit ft*lbs. but that’s not the point (and the “rotational energy” thing is indeed a marketing gimmick).. I outlined the benefit of the fast twist in my post you quoted. Read it again.

          I used to be like you, thinking energy is everything. You’ll grow out of it

          we've got a new ballistics term that nobody has ever discussed before.
          >half the recoil
          and half the energy. there is no free lunch in physics, my dude.

          This is hilarious, because the term I used that you laughed at IS the free lunch. If both cartridges are getting equal energy at 500 yards, the one that starts off with less energy will have less recoil, a smaller case, higher capacity, etc without degrading its terminal performance at 500yds.

        I don't doubt he was significantly involved/caused their murder/deaths, but I still don't see how he got it all done in the time allotted. if I remember right they never found the AR that he wasted his wife with, but I don't know how he disappeared it or did the whole

        I find it nearly impossible that other people weren't involved but they stopped looking and were like

    America tries to make 9x39
    Except that doesn't make any sense, because 9x39 is scaled up 762x39, and 762x39 is/was the Russian equivalent of 556, and that position already belong to 300 BLK
    Except that doesn't make any sense, because 545 is the Russian response to 556, so that would be the Russian equivalent to 556 and 762x39 would be .300 blk equiv and that makes sense because they have similar performance and this means 8.6 is the American 9x39
    Except that doesn't make any sense, because 8.6 doesn't seem to be in an AR platform in OP's pic like the 300 and 556, which means it doesn't follow the AK's pattern of 545 - 762 - 9 and the honor should probably go to .458 socom.
    Except that doesn't make any sense, because .458 doesn't match 9x39's purpose which brings us right back to 300 blk for short-range subsonic sentry slaying
    Except that doesn't make any s-

    A flop on all levels
    Firstly, the name doesn't make sense. It should be 330 Blackout
    Secondly, the cartridge doesn't make sense. 338 Spectre does everything this stupid cartridge can but in a smaller package. With 22 nosler/350 legend as a parent case you don't even need a new bolt anymore. Maybe PSA will do that and trademark the 330 aac blackout name kek
    Thirdly, short action cartridges can shoot a lot more mass and have subsonic cartridges that don't get mogged by 45 acp. Rotational energy goes up by the square of bore diameter and linearly with mass if you wanna do meme bullets. 408, 458, or 510 to name a few would mog this failure of a cartridge.
    For me? It's the 50 American Eagle, the best subsonic short action round

    It's literally just a copy of 9x39. What's so special about it and why bother making a whole new caliper instead of just using 9x39?? In fact 9x39 is very slightly better because of the bigger caliber.

    When it comes to hunting, which is what 8.6 is marketed for as far as I've seen, shot placement is all that matters. Half moronic Alaskan Inuits kill bull Moose with .223 regularly. Half moronic West Virginians kill white tail does with 12g slugs regularly
    So if suppressing your hunting rifle matters to you then yeah, 8.6 is legit. But don't act like the flashy massively exoanding high-twist rate projectile is ever going to compensate for shot placement

    Every rifle round invented after .308 is a meme but as long as it can kill criminals then its a good cartridge in my opinion.

    8.6 blk might have been more popular if it fit in an AR-15 action rather than an AR-10 action. We were so close to a western version of 9x39mm, but Q would rather have another deer killing round that will get ignored once hunters realize that their 30-06, .308, and 30-30 have had no problem killing deer at all.

          Agreed. But 338 spectre is a wildcat that nobody sells. I have an LWRC receiver spec 6.8 SPC that I put together before I realized 6.8 SPC is a meme. I Wish there was literally any sensible alternative to chamber it in. I’d love a 338 spectre, but I’m not gonna load ammo for it.
