I occasionally practice with both a 642 and a 64. I shoot lead at the range - its a requirement if I want to shoot their steel. I recently ran about 400 rounds through the J frame without cleaning. The cylinder was moving freely so I figured it was good to go. When I charged the cylinder with Hornady Critical Defense 110s I found that 2 of them would not chamber due to lead build up. I was able to remove the build up with a brush, patches, solvent, and time.
Would use of a boresnake or brush at the range be sufficient to keep the build up under control? How about an oversize brush?
I keep the J frame in a drawer with a pair of SL Variants nearby and I would hate to find that the revolver won't close when I need it to function. I usually shoot 25 or 50 rounds in a session so I don't want to scrub and patch all 5 cylinders every week.
I guess I could go jacketed but I like practicing with lead.
Is there another solution to this problem that I don't know about?
