Richard, lots of these fellas must be shooting dirty barrels. For me, most months Suze and I leave after the match and go to Gulf Shores. That being said, it is usually a week or so before I clean the rifle. I saturate a bore mop with Kroil and run four wet ones down the barrel and then wet the thing good and leave it in the neck for a time. When I come back, I will run a brass brush back and forth five times. Then a couple of dry patches which are always black. Next a couple of Boretech Eliminator patches. Then I mix Iosso and J B and coat the barrel well, brush, clean up with more Boretech, couple of patches of carburetor cleaner, admire how clean she got. I am not promoting these products, many others will accomplish the same thing. WWE
