Are you old enough for a pistol permit yet?
Not quite yettttttt...
BUT, I have done a little experimentation with my C&B revolvers. As two controls, I used my Old Army (7.5'' barrel), and then my cut down 1858 Remington (this was on a build thread a little while ago around here).
I used 200gr .452's (all cast) & then your typical .454 round ball (130gr-ish). I had to patch the bullets when using the Old Army on account of the chambers spec'd at .455-.456.
With less powder capacity, the .45 boolits all seemed to hit wayyyyy harder & penetrate more wood than the round ball did even at the RB's far higher velocity. (barrel length not regarded here as more than a definable measure to make the comparisons against)
I love experiments.
Sometimes you just have to Cowboy Up.
