Goal is a 6BR load that will load from a MDT 6Br magazine. Maximum OAL 2.257. Went with the 80 gn Berger and 8208 XBR. I did the load test in two runs. 27.0 - 30.0 then a second test from 29.5 to 30.3. Seated the bullets .050 below magazine length to give me some wiggle room. Next step is 25 at 30.2 shot at 300. I think I will leave seating depth alone. I have .050 to play with magazine wise and .075 for single feed if I ever want to tweak it a bit
