I have a KM77 MKII VT, and was wondering what the recommended torque is for the action screws. It has a laminated stock. I know that the middle screw should be just snug, but am a little unsure about the main fasteners. Any other thing " quirky" that anybody may know of would be appreciated.
Happy New Year.

I have one and sent it back to Ruger for being "inaccurate". Well they said the action screws were loose. I had them torqued at about 55 inch lbs. The guy at Ruger said 95!! Shoots sub .5" groups now.

Wow, that seems high, but if that is what the factory says! I know that this is laminated wood too!

I agree it was high to me. I had to buy a new torque wrench.

I bought a Fat Wrench awhile ago. It stops at 65lbs. But I torque my wood stocks rifles at 45lbs.

I hope that is inch lbs!

I have one of those, and use it on every dis assembly. What a awesome little device. It has all the bits commonly used in our hardware, including hardware for scopes, and bases. Imay have to use my in/ lb torque wrench from work if it is 95.

I cannot imagine 95 in/lb. Must be a mistake. I would ask another person at Ruger..... I'd be willing to bet you'd have a heck of a time keeping a standard flat bit in the slot with that kind of torque. I have difficulty keeping it in a Mark X with 45 in/lb!

A friend that shoots 1000 BR starts out with 35 in/lb rear and 40 in/lb front and tweaks some from there. He can actually fine tune the groups by changing the torque. It would seem every BR rifle has its favorite torque.

We both use in/lb torque wrenches on our hunting rifles. If it is a laminate or synthetic that is bedded we run as high as 55 in/lb front and rear. Some respond well to lower settings. If a rifle is pillar bedded I doubt you'd see any differences with higher (than 55) torque settings.

AZ, I have to agree, that dos seem to be high. That is nearly 10 ft/ lbs, on a slot head, like you said. If it were Allen, or Torx, no problem.
And I know what you mean about being able to "tune " it changing the torque. I have gotten to be anal about returning to the correct torque, after dis assembly. I also check it at the range, and when I go hunting.
I may have to do some additional checking, and that is NOT to say that I don't believe what I was told earlier in this thread. Thanks for the feedback!
P/S, I have it set now at 45 in/ lbs., and the center screw just snug.
