I have a Wheeler Scope mtg kit.There are 2 small levels that come in the kit.One is to be mounted in the bolt area.Well unfortunately there is not a good true level area across the open bolt area.My rifle is a Mossberg MVP which is a decent tackdriver usually shooting .5-.7 moa.My problem is the scope is ever so slightly canted and my eye relief is not setup properly.What is the best way to setup eye relief ? Hold the gun comfortably and have someone slide it front to back for me until I get a full sight picture ? Also has anyone used the Wheeler gold colored barrel clamp on sight level ? Any suggestions on getting my reticle true with no cant ? Thanks Ed
