My tang safety model must be an exception. Shoots great. Not a No. 1 though and I have no experience with them.

I will say that Ruger M77MKII bedding is oftimes in my experience ATROCIOUS and needs immediate care. A dab of Acraglas gel behind the recoil lug and freefloting the barrel seems to take care of the issues. Neither of those fixes will help you directly with the No.1, except to say that the fix may be rebedding the forestock as opposed to the barrel itself being bad.

Ruger triggers are notorious for their completely unusable condition as-new. Merely fixing a BAD trigger helps so much in rifle control and hence accuracy. Are the trigger pulls on No.1's any good?

A guy can send a 77 rifle back to Ruger and request "Trigger Adjustment; Minimum Pull" and on 77's they have charged me $20 and have done pretty good work. Do NOT ask them to do a "trigger job" on the rifle or they will send it back to you with a note saying they don't do such things. Can you say "Alan Dershowitz", or "The Ghost of Johnny Cochran"???
