i been casting for a while now for my 9mm, .40, and .45 but i have never used gas checks...i found a good deal on a 35 rem barrel for my contender, im going to cast for it and use gas checks,, 1) can you install gas checks on a star machine and if so do you still put the slugs nose down??? ..2) do i need to size them to .359 which is .001 over jacketed bullets like i do all my pistol calibers.. or with the gas check do you size to .358????... thanks for replys as always....bill
