any body have a decent scope for a pump shotty? i have a 4 x tasco on it right now. im fine with just 4x magnification. but after shooting the other day i think my scope might be broken. i was trying to sight it in the other day and even making huge adjustments, i was only hitting the the right side of target. elevation worked just fine. but i could not bring my 3 to 4 inch group any closer to center than the outer ring of target. and that was brought in from off the paper. so could it be me? my scope? whats the most plausible i guess. i do know that my mom had fallen with this shotgun a few times so that is why im leaning towards trying a new scope.
