consistently the misses were down to pilot error, I think the 6.5 would be a lost cause at the present level of knowledge in cast boolits the weight would
be down to about 110-120 grains, I have tried in a 6.5x55 with a 8" twist and the Lyman 266673 it is very hard to get to 1700fps the boolits are going side ways at 50 metres, a 7mmXCB is the best next option:D My goal is to shoot sub 3" groups at 200 metres, we have a 200 metre CF Silhouette shoot at the local range all the targets are scaled for 200m, the need for speed is not that important but the more velocity I have is a bonus,
