Dimensions for scope mount base holes on Accutrigger receivers

[johnsopa]

I'm trying to customize a couple of scope mounts for my Savages.

Does anyone know the as-designed dimensions for the scope mount holes on a short action receiver?

I'm getting 0.870" between the front holes and the same measurement between the two rear holes.

I'm also getting 3.925" between the second and third holes.

I'm also getting 0.150" or so from the face of the receiver to the first hole.

Maybe I could just call Savage and ask them but I suspect I wouldn't get far...

When I make custom bases per gun, I always go off of what the screw hole spacings are. That way it fits perfectly. There are several after market bases and or rings that will fit right on without having to modifly them.
