I have a new 28 Nosler Christensen Ridgeline rifle. Purchased new 4 days ago. Started break in with factory 168 Nosler Customs. Bolt is a little tight when feeding a round, a little tight after fired, and some pretty decent exctractor stamps on every round. Can someone give me some insight or advice on what’s going on here? I’ve heard everything from head space, hot loads, etc. I haven’t fired anything else through it, but seems unusual for factory ammo? I was gonna start loading with it, but not sure what to do from here and if the gun needs to go back?
