I have been searching the threads on the 8.6 Blackout, and saw some issues with the 1:3 twist over spinning and causing damage to suppressors, etc. I probably should have researched more before I put my rifle together, but I used the Faxon 16" barrel on my Aero AR-10 build. I was zeroing it in yesterday and had no consistency in my groups.
I have a Trijicon Credo 1-8x scope using a Griffin Bushwacker suppressor and Gorilla 285gr. fracturing ammo, the stuff for the 16" barrels. Confirming everything was tight, still had issues. I did inspect my suppressor for any baffle strikes, but everything looks good there.
So wondering if anyone has some thoughts on this? Would I be better off going to the Mos-Tek 1:6.5 twist barrel? Different ammo? What twist is best for that 285gr?
Thank you
