Not that anyone cares, but I did some chronograph testing with my Blackhawks: the 7 1/2" barrel vs the 4 5/8". The ammo was the Buffalo Bore +P .45 Colt with a 225 Gr projectile.
I was surprised that the extra 3" of barrel barely increased the velocity at all, well within the variance of one round to the next. Also, the purpose of this beside comparing the barrel lengths was to confirm that it would be Colorado legal for big game out of my guns, which it is.
