I'm getting leading everytime at the range. I'm shooting 44 mag with 7.7 grains of Titegroup behind a 240 grain Lee C249-240-SWC. I am not using a gas check even though the bullet is made for a gas check. Sized to .431. I'm shooting them in a Ruger Redhawk and a S&W Model 69 and coating them with Eastwood Ford Light Blue and Ford Dark Blue (one coat). I'm thinking that I need to put 2 coats of the powder coat on the bullets. Anyone have suggestions?
