portland or
Took my Mrad out for the first time with a Steiner M7XI 4x28 mounted on Sphur 4602 20 moa and the Mrad has 10mil rail.
When i tried to zero it in best i could get at 100 yards was 2.5 inches above bullseye. My question is do they make shims for it or do i need to order a 30 moa base
On the brightside its dead on at 300 yards and shoots great
 
Sounds like what you are saying is that you have no more down adjustment. Your combined scope mount and rail already have you at 30 MOA cant, more cant will get you more distance from the scope and not less. Not familiar with that scope but as previously suggested check for zero stop that may give you additional downward adjustment. Your only other option is to change the rail to 0 MOA or mount to 10 MOA or 0 MOA.

Where i went wrong was thinking the rifle had a 20 moa cant and the scope manual wants 40 moa so i got a 20 moa base I am hoping i can shim it otherwise i need a new base
 
You are hitting the zero stop.

Have your turret lined up with “0”.

Looses the cap and zero stop with the Allen wrench provided in the box (there should be two screws).

Line up the turret to 10 mils. Tighten down the set screws. Now dial down to your zero.

If by chance you have zero adjustment down, then you need to get a lower cant mount.
 
If you’re actually bottomed out, which you’re not, adding more inclination to the rail will only make things worse. Not better.

Is it a 10 MOA or a 10 mil base? If it really is 10 mils, you are at 15.8 mils with the mount. I haven’t looked up your scope but assuming it is the 26 mils of adjustment that others have mentioned, that may be part of the problem.
