how tight does the gas check need to be?
these are powder coated and after running them thru the sizing die i noticed that a few gas checks can spin
on the back of the boolit.
do they need to be very tight?.....tight? barely held on?
if they are spinners... will the check come off during the big bang? ....in flight? or does the spinning action ad 7 extra horse power like my J.C.Whitney catalogue says?
