There are revolvers chambered for the .45ACP. It will be interesting to see, given identical barrel lengths, what the Chronometer says about muzzle velocity in an Auto vs. a Revolver! Has anyone seen such stats?

According to my Speer manual 5th Edition, a .45ACP fired from a Freedom Arms Model 63 Casull, a 230 FMJ with 5.3 grains of Unique gives 900 fps. A Colt Gold Cup, firing the same bullet with 5.7 grains of Unique gives 750 fps.

Supposedly the bullet is long gone before battery is unlocked, but it does look like the action takes Power for cycling and how it is taken from the ballistic energy, I don't know, but that could explain the difference.

Isn't that a 6 inch barrel vs a 5 inch barrel? I think that barrel length is by far the most important part of this discussion.
