bp pistol pressures

[mylo68]

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

I don't know what the actual pressure is, but the load you are describing is right in the middle of the loads listed in the T/C manual. The heaviest load they list in the manual was 30gr, the lowest is 20gr
