I just started working up a load for my new barrel. Its a 1:10 twist McGowen 22" varmint. Been trying 168 matchkings and the 168 harnady match with varget and BL-C2 with CCI large rifle primers. anybody have suggestions? My powder weights, and C.O.A.L. is VARY uniform. Only using for target so how far should i be from the lands?
