The forend stays tight but every 4 shots I can apply the same torque to the screwdriver and the screw easily advances clockwise about 1/16” tighter.

Then best of all my elevation POI changes wildly every time.

So seemingly the same torque on the forend, but screw ends up further in, and POI shift is in the 6-8” range of change every time.

Good grief. I’ve never seen anything like it.

The metal insert in the forend doesn’t seem to be going deeper, the screw isn’t bottomed out in the barrel stud.

I’m baffled and I’m at the point where it looks like my fun project gun isn’t even worth taking out hunting.

8” groups even still. Something is off and evidently I’m beyond my pay grade. All other guns I’ve ever hand loaded for have been sub moa. Unreal.
