Y'all keep using the word "ethics" and "ethical", this chap apparently has no idea what that means...
I don't know where this MYTH got started, but that is exactly what it is. I know; I have chronographed many loads. The amount of velocity gain per inch falls off, but the velocity does not drop off up to at least 30" in a 12, or 32" in a 10.Two inches of shotgun barrel is pretty meaningless for velocity. They seem to peak and plateau somewhere in the early teens, barrels in the 24+" range often develop less velocity than an 18-20" barrel.
