Some questions-
-I bought a 12 gauge insert that cast a laser, thinking that this would help identify POI of barrels, but I guess this would only show where the center of the chamber was pointed and have little or no influence on pattern centers?
-It seems like POI should be measured at the distance most shooting would be done? 22 yards for skeet perhaps? 35 yards for the 1st barrel at trap and maybe 50 yards for the second barrel? Games guns at...........

PULL!
