I'de like to ask your guys opinion on something, I recently bought a T\C 209x50 encore for the fast apporaching deer season. It groups great at 50 yards buy I'm having some trouble, the gun conistantly groups about 2' to 2.5' high and there is no more adjustment on the iron sight. Right now my load is 100 grains american pioneer powder in stick for with 180 grain Mag Sabots. Is this normal for the gun to shoot this high or is the sight maybe in need of some work? Thanks in advice.
