I use what ever I have and will fit . I use big patchs with small rod/end piece or a small patch with a large rod/end piece . The only time I have issue with the size of the patch is in my .22 barrels . I'll even wrap the patch around the bore brush and push it through the barrel . That works real well with shotguns .
As of this date 8-18-14 at 6:42am I became a proud grandfather I guess I'm officially old
I hear Glock just came out with a new pistol . I hear it's a tribute to the senate and the house of representatives . It's called the congressman . It hardly ever works and can't be fired .
