As a kid I shot many 00 buck crudely swaged and resized by drilling a 5/16" hole through an aluminum or brass plate, then countersinking the hole, smacking the buckshot through with a punch and hammer, then lightly lubricating the bullets with liquid floor wax, back in the days before Lee Liquid Alox. Used a .22 Short case as a dip measure with Bullseye and used in any .30 cal. rifle from a .32-20 or .30 M1 carbine to a .30'06. Never had any leading issues. Frank Marshall showed me how. Works in any .32 revolver too!
