Re: Removing lead build up in barrel
we are very lucky today. You can buy a number of good lead and copper removers. I like Sweets it works great. Leading is caused more by gas cutting than anything else. I have shot many pounds of wheel weights in the .44 Mags with no problems. My loads run from 1,200 to 1,400 FPS. The problem you are having is due more to a cast bullet too small to bore. A cast bullet should run larger then the bore of the gun it is fired in. Lets assume your .44 slugs .430 your cast slug should run out at .431. The lead drops form at very high heat as gas is allowed to pass around the loose fitting bullet. These superheated lead drops cool and adhere to the bore causing leading. You may also want to check the choice of powders. I have found Win 296 to be very good in the .44 Mag. For heavy loads a gas check and water dropped bullets can also aid in leading reduction.
