I have a B-14 HMR that I'd like to rebarrel and I keep seeing threads that say you need to accomodate the bergara coned bolt but I've started to wonder: is there a safety issue with using a standard remage barrel? I know the front face of the bolt lugs (the coned, non-load bearing side) will be air gapped but is there a problem with that other than it may not feed as well? I know there are a couple shops that make b-14 specific prefits, but I'm curious if there is a safety/functionality issue that requires the chamber end to be contoured to match the coned bolt.
