Looking for a 480 Ruger Mold to cast a bullet of approximately 400 grains with Gas Check installed. Tangential Ogive design, with about an 80% Meplate, and a single Lube Groove.
No luck finding this as a standard off the shelf mold. Really cannot believe Lee does not make one like this. Basicly a larger version of the .429 / 310 Gas Check Mold.
Looking at Mountain Mold at the moment.
Opinions, advice, experiance with Mountain Mold. Other options for a mold like the one discribed..
