I have tested primer pocket cleaning versus uncleaned at 600 and 1000 yards and it’s just noise, it makes no difference. Because of this I stopped cleaning primer pockets 2 years ago. As for the outside of the necks, I will wipe them down really quick with a crazy cloth after every 5 firings (which I keep track of in a book, but I’ve also tested 5X fired uncleaned necks against 5X fired necks cleaned with a crazy cloth, and again it was nothing but noise. I merely do it every 5X firings for a tiny bit of piece of mind. Although, as a side note, I just started this process on my .284 brass at the end of the 2022 season. My Lapua brass for my 6 dasher has 23+ firings on the brass and I have never once cleaned the outside of the necks, and it’s an absolute hammer (see the pics of the brass necks and patina below).What do you do about the outside of the necks, and primer pocket?
