Only been involve with muzzleloaders for a year or so. Had a friend introduce me to a TC Renegade in .50 and it followed me home. Had some pure lead around (old sailboat ballast)and have been casting RB. Having some issues with weight consistency. Tried temp changes, as well as Lyman (steel) and Lee (aluminum) one and two place molds. The one place Lyman seems to be most consistent. Anyone have ideas on what I might be overlooking? All cast with the same pot and lead (didn't add any extra while casting to keep things the same).
