    If I had your mold I would cast with WW alloy, PC them, size and load. Sounds like the perfect opportunity to delve into the PC opportunities.

    I've had this exact scenario. I have a 330 grain SSK for 44 magnum that drops slightly out of round, .429"x.431". As cast, and sized/lubed in a .431" die, I never got the accuracy I wanted. This also left a minor amount of lead. Beagling the mold, I can get them to drop .430"x.431" (that's right, they become more round). Leading goes away, and accuracy is improved. Some other tests with multiple layers on the mold have produced even better results. One day I'd like to lap that mold so it drops at least .432".
