I called Ruger today, and my M77 7 x 57 is a 7mm Mauser cartridge. Made in
1975. Seems there is an aftermarket screw that improves trigger performance
that they are sending me gratis. I appreciate the help from those who
answered. This is an awesome group. Politics, bull****, and all. We still
get a lot of stuff done.

Try it before installing the screw..and afterwards. IRRC..the screw
may be a Lawyer screw. Increases the trigger pull.
