I have a sightron 10-50x60 scope sitting on a 20moa murphy base and still have 18 moa down left in scope, any other scope placed on this rifle is usually 2 moa from being bottomed out. IOR, Vortex all the same except this one. Is there anyway I can get some of that back for more elevation without going to a 30moa rail. shooting 215 bergers in .308 so need all the up I can get have 38moa up left right now. Looks like I will need 36 moa to get to 1000yds thanks.
