I have some Hi-Tek coated 9mm bullets with two coats of paint on them. They pass the smash test and acetone wipe test. They are cast from range scrap and are 11 BNL hardness. When I shoot them through my comped pistols I am getting lead deposits in the comp ports. These bullets have been sized to .357" for a .355" slugged KKM barrel.
I'm going to take some of these Boolits and then add one additional coat to one batch and two additional coats to a second batch of Boolits. Therefore batch one will have three total coats and batch two will have four total coats of HT paint on them.
Question, if I add one more coat of HT will it stick since the load bearing surface of the Boolits have been sized?
I am doing this to see if more coats of paint will eliminate leading in my comp ports.
Should I size the bullets again? After adding additional coats of HT?
