Re: Weaver Tactical Grand Slam ?
If you are saying that are are zeroed and only have 6 MILs of up left then what that means is that you had to use a lot of your adjustment in order to get your gun zeroed and you don't have much left for dialing in distance.
A couple options if 6 MILs aren't enough. Get a angled base and then remount.
Buy Burris signature rings and use their offset rings to angle your scope more like you want. Remount and be happy!
