This is a new thread I decided has a place here on the forum. After being a forum member for a couple of years as a Grendel owner and most of a year prior to that reading posts here I have learned a lot from many spirited discussions by forum members. So why not have a spot to to keep spirited discussion alive specifically pertaining to gun cleaning practices.
I will go first. Copper in or copper out?
I generally like a clean barrel which includes copper. I find it a tedious task to say the least but I like as few variables as possible for accuracy. And yes I should have spent higher than PSA but my 20 SS barrel will get me .75 shooting 120 gr Sierra pro hunters over 28 gr 8208.
