Today after shooting my 45/70 handi, I couldn't find my cheapo plastic jag. I wrapped patches around the .45 cal brush but wasn't satisfied with the results. Looking in my pistol bag I noticed a 38 special fired case fit perfectly snug in the bore with a patch around it. I pushed it into the chamber with my thumb and then down the bore with the cleaning rod. Perhaps I have been playing with the muzzleloaders too much lately? This may be a well know thing but I just wanted to share.
