Dewey rods makes a muzzle protector. You can order direct what you need. You can also get jags, brushes, coated rod and patches from Dewey. Just specify the caliber. From the muzzle using the protector, slip the coated rod thru with a patch wet with Hoppes. Two wet patches, a few wet brushings and two dry patches and your lead is out. Lead is the easiest thing to get out. You will feel it and see it on the patches. Next, Copper. Use Sweets or a similar product the same way, thru the muzzle. Your copper will now be gone. Run a one patch of wet Hoppes, then a few dry patches. You are ready for cast.
