Nothing wrong if you are shooting 1500 + yards only.
The problem with big MOA bases is that you can't zero at normal hunting distances.
Most top end scopes have a 80 or 90 MOA total range so if you use a standard base you
will be somewhere in the middle of the turret range and if you want to shoot 1000 yards
40 MOA=approximately 400 inches at 1000 of come up.
If you place a 40 MOA base on a rifle to start with your scope will have to be at the bottom
of the turret travel and end up approximately 40" high @ 100 yards.
For most hunting rifles 0 to 10 MOA bases work best and keep the scope in a good operating range.
So if you place a 20 MOA base on a rifle with a scope that has 95 MOA built in that will give
you 65 MOA total up from a 100 yard zero for the scope(20+45) .
65 MOA at a thousand yards is 650 Inches of come up.Most rifles only need 300 to 400 inches
of elevating to hit.
What I recomend for base MOA is to look at the drop from 100 Yards to max to be shot based
on bullet performance and skill, and find a base that keeps the scope in the middle of its range
without bottoming or topping the turrets out.
I hope I have explained the need to pick the right base for best performance. this is a place
that bigger is not necessarily better.
PS; If my math is off feel free to correct me . (I have not had my coffie yet).
