I mean NRL22 shooters have been getting sub-MOA with subsonic rounds for a long fucking time and we're running 1:16 mostly.ģ00 BLK subs can shoot MOA. sub-moa for the first time with subsonic rifle cartridges. With really fast twist barrels we're able to get really small groups. And again, what form the energy is in doesn't fucking matter. Period.Ī 12' 8.6 will have more muzzle energy than a 20'.

Rotational energy gives you much more energy on target That said, I'm really not confident in their claims mostly because what Kevin says in marketing videos is fucking retarded. I'm half-guessing at the science but I would imagine that very high rotational energy basically acts like a propeller in soft tissue. Twisting that fast, jacketed rounds don't tumble - they disintegrate. Q specifically states that the super twist cannot be used with jacketed bullets and must use solid alloys. The question is how much linear momentum is lost, does this degrade barrels faster, how much does this improve terminal ballistics, ect. Faster twists which push projectiles to their centrifugal limits may be unsuitable for light supersonics in longer barrels where higher velocities (and therefore RPMs) are achieved. Fast twist should never harm accuracy with fast projectiles, as long as point #4 is considered.Ģ) Very fast twist is important for accuracy with slow long bullets.Ģ) Faster spinning bullets have more centrifugal force acting on any expanding components of the projectile and will generate a more significant amount of turbulence in fluids when they expand for any given linear velocity.ģ) You can spin a bullet too fast and cause expanding projectiles to open mid flight or multi-material (such as jacketed) projectiles can come apart, which can be a dangerous and potentially costly safety risk if protectile fragments miss wildly off target or destroy your baffle stack. The claim is that the conversion of energy from burning the powder to kinetic energy is more efficient with a faster rotation, they claim a lot of the energy lost used as heat and sound goes into the rotational energy and negligible linear momentum is lost.ġ) Overstabilization is a myth. Literally fucking no one is hunting anything with those numbers at that range. The supers will have ~616-675 ft.lbf at 1,000 yards. 338 diameter cartridge yet it exceeds the energy of most all big-bore cartridges at 1,000 yardsĪnd I mean it might be true, but who the fuck cares? While shooting the round at the range, it had startlingly light recoil for a. I'm seeing a lot of people saying something along these lines: Is 200 ft.lbf a huge deal? Not really in this context, but cut another 2' of the barrel off and lose more MV, and the 200 ft.lbf becomes ? and it's a larger gap than what should be allowed as 'marketing'. 4 years ago they were calling it 8.6 Creedmoor, but I guess Kevin's ego didn't like that so now it's officially 8.6 Blackout.Ĩ.6 BLK supers are 210gr at ~2000 fps from a 12' barrel = 1865 ft.lbfĨ.6 BLK supers are 160gr at ~2400 fps from a 12' barrel = 2047 ft.lbf This isn't really new information either, Q has been working on this for a while. But it also wouldn't be remotely the first time that Q played up their product. That said - the math seems a little sus, but I haven't spoken to anyone involved directly so maybe my napkin numbers are wrong. If you see posts like that going forward, please report them so they can be removed.Ĩ.6 blackout has nothing to do with long range, just saying.
