hi guys new post, this should be a good place to ask about pressures, Ive been reading a good few posts here but haven't yet come across any psi pressure ratings for muzzle-loading pistols,,i quite fancy the patriot .36 cal with 25 fffg and round ball but am curious as to what the average psi pressures these pistols have, any info on proof tests of any other black powder pistols would be great, thanks in advance,.Mylo
