Check Brownell's website. The best tool for deleading the bore as well, is a Lewis Lead Remover. Outers made one as well, but it is not as good for several reasons. The Lewis has a larger diameter rod with a "T" handle, which traps the bronze screen between the rod and the tip when tightened so it can't be stripped off while pulling it through the bore. The (rubber and brass) tips come in sizes for each caliber, 44,45,40,38 etc. The kit contains the conical throat adapter Cheyenne mentioned for deleading the forcing cone. The basic Lewis will strip the lead and fouling from a bore in a few passes, and from experience, 45Colt needs it. A wire brush simply can't compete in that race. The kit also comes with a supply of wire mesh screens, there are sizes on those for 45 and 38.
