I'm not really into all that ballistics stuff as much as I should be. While I am sure the longer barrel helps in the velocity a little, just how much I have no idea. My revolver has a 7-1/2 inch barrel with target sights, and that thing will really shoot. We do a lot of plinking with them. Very accurate.
Sounds like alot of fun. I'd like one myself, but I'd like to have so many other things that it'll have to wait

. Lee, I think, has taken 2 deer with cap and ball revolver. Maybe not BOOM-flop but definitely crack-flop.
