From another thread on the same subject in Special Projects, discussing how the original bullet for this caliber had a heel or minie type hollow base and it was decided that $250 for a mold from Lee was out o the question, which I aggree with! Got me to thinking, why could you not just make dummy block to hold the slug, or even just buy another double cavity Lee mold, put the slugs back in the mold and just use a drill press with a stop on it, to dril a shallow base out in the bottle of the slug, to achieve the same effect?? I use the Lee 450 grain .501 mold for the .500 S&W in this caliber cast relatively soft, unzised and pan lubed with good results, I think this is worth trying, what do you guys think??
