A couple of years ago I broke down and bought a Lewis Lead Remover - Brownell's sells them - and I really think it's worth the cost if you shoot a lot of lead, especially for a revolver (due to the forcing cone attachment). There are certainly other ways to remove leading, but few are as quick. One pass with the LLR is usually all it takes to get it cleaned up. I like that.
If you shoot multiple calibers you can simply buy the extra jag set and screens without buying a whole new kit.
