Hey guys. Just a quick question. I purchased a barrel from a guy on here a little while ago. Was a 243AI. I took it to a gunsmith the other day. He called today and said it needed to be reamed .015-.018 to headspace correctly. Said he could rent a reamer or I could find one. I have contacted the seller and he said it was headspaced perfect on his action(rem700). He was more than willing to help me out. A great guy by the way. My question is should I be looking for a new gunsmith or could the barrel need to be reamed for my action?
