So I've got this problem......
been trying to mount a scope on my mossberg 500 slug gun but the scope just isn't working out. I initially thought it was the scope so I bought another with the same results. I mounted the scope as low as I possibly can but the crosshairs just won't adjust high enough when boresighting it. I simply run out of adjustment. Obviously I can't shim the mounts because it is a cantaleiver style base but can I shim the scope? meaning put something between the scope and ring? If so, What?
next question. the scope is a calibrated scope for the hornady slugs I'm shooting. Think that will mess up the yardage calibrations?
