    Interesting. I wonder how much difference using something like Swiss BP would make in velocity. Probably not a huge difference, but it's worth a thought.

    You video popped up on my youtube last night.

    nice work.

    I run 35gr in my 1860 Army with balls, or 30gr with the LEE bullets in this pic. ( GOEX fffg)

    I need to chrony them, but going from 30 to 35 seems like a bit more thump

    Very nice video. I would also like to see another video of the same guns with the lee 200 gr bullet and speed. Also it would be nice to see you shoot 6 shots at 75 yards .great video

    Loved the video, thanks for doing it. I had trouble chronographing black powder, the high speed cinders would register. 2,500 fps out of a Colt’s Army .44 didn’t look right.

    Like you, I love shooting my cap and ball pistols, but I only shoot them once or twice a year.

    I've had several viewers recommend Swiss, and Triple 7 for higher velocities. I picked up a can of Triple 7 over the weekend. I'll be testing it in an upcoming video. Stay tuned!

    I was surprised at the low velocities recorded. It was years ago, but my 1860 Army sent the same .451 balls down range at about 700-725 fps, over the same 30 grain powder charge. Even with energies on par with a 32 S&W, those 138 grain balls would still put a hurt on the recipient.

    It would be interesting to see how period correct conicals would do. From what I have read they were preferred by some for combat loads.

    excellent. here's some comparison numbers, might help with further research. I find triple seven does seem to result in higher velocities in the remington pocket, and the old army. not so much in the italian new army I have, though.

    Those are more in line with what I would expect from a cap and ball six shooter.

    Thanks for the video. I have a colt 45 trail boss load with a 255 grain boolit that averages around 575 FPS. Just enough to get the job done. I see air rifles marketed to harvest deer with that aren’t any faster. I would assume out to 50 yards would be acceptable with both your pistols on whitetails?
