RE: Shotgun range?
Several years ago I saw a breakdown on the ballistics of 2 3/4" , 3" , and 3 1/2" buckshot (00) and actually the 2 3/4" pellets had better performance due to there only being 9 - 00 pellets in the shell while using the same amount of powder. They may have changed that by now, I don' t know.
