Heya
Got a question for those who use a chronograph regularly, regarding velocity differences in .357/.38 revolvers with 4" and 6" barrels.
Using the same loads, shot out of a 4" gun and a 6" gun, what would be a general, rough estimation of velocity gain from 4" to 6" in velocity per inch, in your experience?
I would guess that different powders will react much differently than others in this regard, and different guns will shoot loads differently from other guns as well, but maybe some generalities?
Thanks
