Video - Round ball vs Conical performance series Part 1

This is part 1 of a three part series comparing the performance characteristics of various projectiles shot from a Colt style 1860 Army cap and ball revolver. In this series we will measure the accuracy, velocity and muzzle energy and penetration of round ball versus conical bullets. Part 1 will consist of the round ball performance test.

Interesting stuff. Thanks for doing this.

Mykeal,

As I said I only shot 4-shot strings...now what I would do if I was running a Lean 6 Sigma project, but enough to judge the relative merits of each projectile.

RB:
886.8
853.9
875.8
913.6

220-gr conical

726.1
674.5
706.1
766.1


240-gr conical

737.5
752.6
670.3
739.5

Thanks. I understand the statistics are not mathematically valid due to the sample sizes, but you're right, they can still provide 'clues' to interpreting the results.
