Having a hard time figuring out which set back. Desert Tech brass CCI primers 44.3 varget. -.050 .400 and .54. -.090 .200 and .370. All look great with most of them coming in under a.500.
I don’t have a 308 barrel for my desert tech, but my other 308 likes the Berger’s touching the lands or .005 Into them. My 6.5x47 doesn’t have any noticeable preference out to beyond 400 yards.
