Factory ammo produced 4" groups. Luckily Brownells took it back after I had it almost two years. Head space was really short.
Thanks for chiming in about your struggles with this barrel Im at my end with it.
I had it out today and it was the same story for me. Maybe they just sent me your old one since I did get it from brownells Its the hybrid profile with midlength gas.
I measured the groups in my scope at like .75 mil average with fliers at about 1.5 mil ????. Consistently inconsistent across different weight bullets and powders.
Broke down the upper when I got home Im not going to spend anymore bullets on this barrel so we will see tomorrow. I would be upset if this was a 95$ Psa barrel - definitely worst barrel Ive ever shot so something must be terribly wrong even with the very nice Jp bolt
