Use Pure Lead for Slug Molds

Make sure you use pure lead for slug molds. We dimensionalized the slug mold to take the shrink rate of pure lead into account to arrive at the correct diameter. If you use alloyed lead (like wheel weights), the shrink rate will not be the same and the bullet diameter will be too large. Also, check to maks ure the mold is closing all the way. If not lubricated as per the instructions, it will be difficult to close all the way, and this will result in out of round, oversized bullets.
