Hey guys, so i was at my buddies shop the other day while he was chambering a barrel for a new 6.5 prc. I looked at the muzzle end that was in the spider on the lathe and it was walking probably .600" around. I said something to him and he looked at me like i was stupid lol. The chamber side dialed at .0001 on his range rod but the muzzle end was everywhere. He tells me that it is perfectly normal and thats how he chambers and does muzzle breaks too. Is this normal? I cannot wrap my head around how you wouldnt want the whole bore and chamber concentric all the way through to run a true center.
