I recently mounted a cabela's slug scope to my 535 cantilevered barrel. I used 1 inch weaver bases. When I went to the range to sight in, at 50 yards all my shots were at the bottom of the paper. I adjusted the elevation turret but there was little to no change in shot placement. I checked the torque on my bases. All were as expected. So if anyone can shed some light on this I'd be greatly appreciative.
