My HW97, with an opticaly centered scope, shoots low. (See 5 shot group at 30 yards)
I have since zeroed my scope to it's max adjustment achieving a 75 yard zero.
I have a set of West Hunter rings that are height adjustable, but the ring angle is fixed, so that they don't follow the scope angle when one ring is raised. The result concentrates the clamp forces to edge of the rings. That could damage a scope and void its warranty. Reading the warranty with my scope, an Element Helix, it says that damage from scope shims will void the warranty. So I've got to do this right.
So, I have begun modifying these West Hunter, rings to be height, and MOA adjustable.
I filed the grooves in the center ring, and trial fit it with good results so far. The remaining grooves in the base grab well.
I will also drill and tap a scope stop screw, which will be adjustable for height then do some testing.
