It might depend on your priming tool. my RCBS bench tool didn't get along with Redding s/holders because the center hole in the Redding was bigger in diameter than the RCBS primer punch. Sometimes the primers tried to go in a bit cock-eyed. RCBS s/holder with matching hole fixed the problem. BR was originally made from 308 sized cases. Same size base, so if all else is good, the #3 should work fine.Is everyone using the RCBS #3 shellholder for their 30BR when priming cases, or is there a better option for the small rifle primer of the BR case?
