Okie, I have had the 77 series Ruger front action screw loosen also.
I have noticed some the newer Hawkeye,s front action screw have a detent or dimple in the screw. Which should help to keep them tight.
I have called Ruger and bought or requested torx style replacment screws, to get them to proper torque which helps in keeping them tight, in unbedded wooden front stock screw will loosen due too amount of moisture in wood.
I use epoxy pillars in my wood stock Rugers to keep them tight, and bedded to prevent breakage.
If my MK 2 or Hawkeyes quit shooting well , first thing I check is front action screw. Kurt
