Re: Anybody have any ideas?
Every 20 rounds is pretty often. It probably takes 3-5 rounds to correctly foul the barrel. I clean mine when the accuracy falls off (or I can't take it any more) maybe 100-200 rounds on some of my rifles.
Did the better groups come right after cleaning, or after a couple groups?
If some is good and more is better, then too much is just right.
My mind is a raging torrent, flooded with rivulets of thought, cascading into a waterfall of creative alternatives
