all shotgun owners should pattern a gun when they buy it.
put up paper with a 30" circle drawn on it. mark center and draw cross hairs thru it. back off 21 yds, choose a choke, and shoot it the way you normally would hold your gun aiming at the center mark.
go look at your pattern.
the holes will tell you where your gun prints by design....if you didnt flinch. if you did, do it again with new paper.
look where the majority of holes are. they will either be equal in the whole circle in all sections, or high, low, left or right. do it a couple of times. get a trend.
now you know where your gun patterns, so when you actually shoot your gun, youll know where that shot is really going. no more magic guessing.
This is really not the best way to do it for a Sporting, FITASC, or hunting gun, but it's better than nothing for any other game that will be shot with a pre-mounted gun.
All it will tell you is where the barrels shoot when you get the sight picture you particularly want and then "aim" at the target.
There's no place for "aiming" in any shotgun sport.
