I shoot CBs exclusively in my 03A3 Springfield. I shoot NRA Highpower with it. I get no leading and great accuracy. Duh !
But I also never get a patch to come out of the bore clean. There's always black on it. I use Ed's Red (homemade.) I shoot about 600 - 700 rounds in a season, and I usually claean once at about the midpoint and then a detail clean and strip at the end (which is now.) I've used bronze, stainless steel, and nylon brushes, and I ALWAYS still have black on the patches. The bore looks clean and brite, just not the patches.
Am I being a nitpicker ?
