morning, im researching a cast boolit load for a hr om trapdoor. lyman button mold at 145gr, unique 5 to 10 gr. the boolits are cast powder coated and sized to .460. (i have a lee push thru sizer coming at .462 ) the question is....does the boolit get pushed down on to the powder or sit at the mouth and crimped ? thanks for any reply. irishtoo
