.338 and ,243 cleaning

Re: .338 and ,243 cleaning

2" round cotton flannel patch over a .338 jag. My 6mm, I use about a 1" - 1-1/4" square cotton flannel on a .224 jag to mop in Butch's Boreshine and a final with a .243 (6MM) jag with same patch. Finish off both with Kroil Oil then a dry patch. I believe the brand of the square ones are Southern Bloomer and the round ones are Pro Shot
