I bought my 1987' Beretta Pintail about 11 years ago unfired for $300. I took it out shortly after to pattern it and was missing clay pigeons left and right. I finally pulled the safe queen out yesterday and tried to pattern turkey loads with it. At 25 yards I tried 3 different shells. I had about 5 pellets in two targets and about 7 in the other. I littletaly missed the targets resting my shotgun. The 7 pellet target they was hit on the very bottom of the target. I figured it was shoot a good 1' or more low. I dont know if it was a factory installed tru glow sight stick on univeral sight or someone stuck it on after the fact but it tore it off and re tested. She's dead on with the factory bead now! I should have known better. I remember my buddies putting similar finer optic sights on their shotguns back in the 80's when they first came out and had the same issue.
