You can change the angle of the lower sear tab to would academically fix an overcocking or undercocking issue. But in the case of overcocking, if you fixed it by changing the lower sear tab angle, you haven't changed the amount of force required to open the bolt any at all. The cocking pin still rides up the same ramp to the same detent; it just doesn't drop down as far to the upper sear tab. If you did this to correct undercocking it would sure enough help out on the amount of force required to close the bolt. Both of mine overcock, but the Stevens only slightly; just enough for functionality. I haven't checked the Savage to see by how much it overcocks.
