Re: which primer for .338 RUM
Funny you should ask, I shot through both of my chronographs today one is a pro chrono and the other is a fairly new chrony f1. Through the prochrono I got 2780 and through the chrony I got 2870. 2830 matches my pda exbal program out to 1250
I did this set up today to test the 215's out of my 300 rum and the chrony showed 3173 and the pro chrono read 3075 for the same shots. My drop charts are leading me to believe that load is right around 3000.
I have a friend with a factory stainless 338 rum and with 91 grs of H-1000 his drops work out to about 2675. His chrony also reads high.
