Undersized bullet, not enough or wrong lube, too high a velocity or something not right with the cylinder throats.
The leading isn't caused because the bullet is scooting, it is caused by gas cutting- the hot gases are being able to get around the base of the bullet and are acting like a blow torch!
I have gotten great results from cast bullets in the .430 to .432 range, but finding a good mould that throws this large can be a problem too- I always got my bullets from a friend that cast them...but now I've taken up casting and finding the right moulds can be like finding the proverbial needle in a haystack!
