Recently bought a 1895GS and went to the range to play. The only ammo I could find was Federal 300gr in the blue box. I set a target at 25 yards just to be safe and i was hitting about 6 inches low and to the right. I adjusted the rear ramp to the highest point and still kept hitting low. I am trying to find somewhere in Canada that sell XS sights but having a hard time and I still want to play in the mean time but not when this thing is shooting like this. PLEASE HELP!!!
