It definitely needs to slope forward, what you are doing is raising the angle of the bore relative to centerline of me on this, I have mounted one backwards myself one time!!

Re: Help scope moa problem

When shimming or using a MOA type mount you need to have the tail end up so much of your MOA(in the scope) is used pulling the rifle down to the paper at short range. I don't use 20 moa rails, but I have had to use shims on the tail end of a scope mount to get it right.
Look at a blade sights rifle; works the same way.... Pull the back sight up higher for more barrel incline to hit on target at longer range. The thing that usually screws people up is you put the rail on and then dial it back out for short range. I'd rather pull up and leave the scope optically centered; that doesn't work much past 800 yards though with most calibers.
