[QUOTE="JTB, post: 1837545, member: 97196"] Agree. Would not “rough-up” the chamber. I really don’t see a reason to be overly concerned with the brass you pictured. If you start to experience heavy bolt lift back off. There are too many reasons for primer cratering and ejector marks to attribute it solely to excessive pressure (relatively high would be a better descriptor). I have seen more problems from rough chambers than from smooth chambers. If it is too rough the brass will adhere to the chamber wall upon firing firing and will stretch the brass just above the head as it presses against the bolt face, resulting in very short brass life. I always lightly finish chambers with a new sheet of 1000 grit paper and seems to work well. [/QUOTE]
