Im thinking of a spending spree...like a vulcan 3hp .30 and a corbins press with .30ish slugs ive read that .306 is the magic size. I would be slugging the barrel when i purchase the gun. Im just trying to plan ahead. My question is does anyone here make these size slugs and would be willing to make a couple test batches for me. Im willing to pay. Id just hate to invest in a press and dies only to find out the gun dosent shoot them well
