I shoot 440gr cast perf. out of my 7.5 in. bfr with 51gr. of benchmark for an avg 1610fps and 2533ftlbs of engergy, it is an extremely accurate load for me but it is also max for my gun. You will also definately know when it goes off.
I won't be wronged. I won't be insulted. I won't be laid a-hand on. I don't do these things to other people, and I require the same from them. John Wayne-The Shootist
