I've acquired a few bolt guns in 6.5 grendel and would like to shoot cast bullets out of them problem is I can't find any data on powders,bullets etc. Cast Boolits site no good,6.5 grendel forum doesn't seem to exist every link I try says no such place. The grendel case capacity is the same as the parent case 7.62x39,figured I could use the lead bullet data for the 7.62 in the 6.5 using Unique. Figure the 125 gr gc and 8 gr Unque is as good a place to start. Anyone shooting cast as well?
