I’ll be testing this combo (but with 103 Copperheads) in near future.. I’ll be starting at 29gns of Varget and work up, 5jump, CCI 450s, Lapua brass. Plan on testing the BR4s for comparison also but have found no difference in the past to the 450s..Vapor trails, been a long time coming. Hope to get an idea on where to start with the 6BR vapor trails
Lapua Brass, Varget or RL-15 powder. CCI 450 primers All information welcomed.
Thanks ACSR
