18" Proof Research - 6mm ARC build and testing - factory and handloaded ammo

[Pig_Popper]

This thread , for ME

Is officially CLOSED / sent back my Proof barrel to Rainier Arms yesterday , requesting they defect it based on inability to shoot factory loading and proof stating it is possible the freebore is too tight.

Back to waiting for my other barrel to arrive ................

Thanks for all your help and support , it’s been a crazy month
