Nice little arsenal ya have there. My 20, before I broke down and bought a red dot sight, was 8 inches off POI vs POA with TSS. Other loads were right on. So I just compensated cause I knew how far off it was. And luckily never missed in 10 shots or so. But then my wife started hunting with it so instead of worrying about Kentucky windage, only then did I add the red dot. Point is, who'da thought POI can be 8 inches off?
Funny part is the only time I missed with that gun was after the red dot was put on. And he wasn't more than 35 yards walking right down my barrel. Go figure.
