Re: Pushing Berger 7mm Berger 168s or 180s??
I accidently loaded a box of 7mm rem Berger 168 Gr with 75 Grains of Retumbo powder. I thought I was loading 70.5. I went from 3020 MV to 3450 MV. The only problem I had was blowing a whole in the primer and getting metal from the primer jammed into the firing pin. No damage to the brass or gun, but due to jamming and primer failure I dropped to 69 grains of powder and shooting an accurate 2912 MV.
In my mind I want to shoot 3000 MV but is it really that important to be shooting that fast?
