I am new here, i thought maybe someone can shed some light on my issue. I have a browning stalker A-bolt 30-06, I've tried the Barnes 150 and 168 Gr. Vor-tx copper And Remington copper solids in 150 gr. And can't get it to group at all. Anyone run into this? If so what was the solution? It does good with Winchester (don't recall exact) and Remington cor -loc, 165gr. Lead ammo, but Cali requires lead free ammo for hunting in half the state.
