Rifle Stock?

Model & Caliper?

What is the breaking point of the trigger completely off the stock?

Is the stock bedded?

Back off the rear action screw. Start at 0 and work up. Start tighten up the screw, 4 ft lbs per turn until the problem starts. Let us know that figure.

Sounds like something is binding, probably in the stock mounting area.

Does the action act like it's rocking in the stock (screws loose)? If everything is correct, you could tighten the mounting screws as tight as you want and it won't bump fire.

Has anyone filed on the sear?
