every one talks about using .600 dia. round balls in there SNIDERS in 24 gauge CHEDDITE, plastic hulls. the problem that i have is after inserting them into the hulls they make a bulge in the shell that keeps them from chambering. i have tried running them back into the sizer die, but no soap! so i revert to loading them with good old .577, 58 cal. musket minnies. that works every time. question, what am i doing wrong? does any one else have this problem? if so let me know.
