8 months later and my 22BR OBW shipped from PVA. Debating if I should shoot virgin brass with 88/Varget or 69/TAC to somewhat fireform the barrel and speed it up.
I always like to put 100rd down a barrel before starting any load development or pay any attenion to velocities... I put 100rd of virgin/newly formed brass down my new 28" MW PVA 0.100 barrel last week with 88ELD 0.02" off over 28.5gr of Varget. They shot lights out....
