I have been shooting at 100 yards.
After zeroing the rifle at 100 yards it is very easy that when you shoot at 25 yards you hit a little bit right or left.
That mean that the scope has some incorrect inclination to left or to right. Not always the weaver or dove tail rail is perfectly aligned.
Giving the correct angle to the vertical axle of the reticle sometimes get time. But your rifle is not duly zeroed until you achieve it.
