I picked up a kit from ebay for 44 caliber. I shoot nearly all lead in 44 special and magnum, because I'm cheap like that.

It's a simple set of pieces that will cost you a little over $30. The barrel-shaped plug is sized by caliber so you have to get one for each size. Brownells sells the plug by itself for $11-12 and I plan to get one for both 32 & 38/9mm.
I cleaned a pair of SW 44s I've shot for years and only cleaned with a bore snake. I didn't think it would pull much out but it did. You insert the handle and rod through the barrel then screw in the plug wrapped in a light screen. I dribbled in some Hoppes. Pull the plug the length of the barrel and bingo! It looked like pencil shavings made of lead coming out. I did this 3-4 times before no more came out. I followed up the lead removal with a bore snake and the bores look like sterling silver.
There's an attachment that works like a forcing cone cutter but it's only a screen buffer for the cone. I did both guns and didn't see any lead removed from there. I guess if you have lead smeared there you've got another problem going on, Bearrr.
In short- works like a charm! A little pricey for what it is but what can you do? I read pipe cleaning screens will also fit the set up and are a fraction of the cost of Brownells replacements.
