Re: 300 RUM Issues...
I am shooting 93 grains of Retumbo with 215 bergers, however, my oal is around 3.670 (max that will fit in my magazine) By extending the bullet out the pressure changes. My chrono numbers are 3075 from my old pro chrono and 3163 from the new chrony. My drops at 700 say 3003. My next shots will be at 1000 to verify the drops again.
When you said you have verified your drops, what was your zero and what were your come up amounts at the distance you shot at?
