It not like they haven't tested this. 1: 3 at 1050 fps is not that much faster (rev/sec) than than that same bullet fired a bit over 3000 fps from a 1: 10 twist 338 Lapua Mag.
When going super sonic you're going to have to select bullets carefully. Faxon seems to indicated that bonded bullets and solid copper designed for super-sonic use stay together but non-bonded cup and core bullets can come apart.
To me 8.6 Blackout is like 300 AAC Blackout, it is a subsonic focused cartridge. I shoot very little super-sonic 300 BO, but tons of subsonic 300 BO. If I bought a 8.6 Blackout I would also shoot very little super-sonic ammo in it. If I want super-sonic 338 diameter bullets in a 308 size platform I will buy a 338 Federal. But if I am going to sling 338 diameter bullets as super-sonic velocity I would just do it right and go 338 Lapua Mag.
I am interested. And if I finally buy a 45 caliber rifle rated suppressor for my 450 Bushmaster this would be the next cartridge bought to be used with that suppressor. A SBR 700 action in this cartridge would be fun.
