Regardless of accuracy, the Ruger 77-22 is a nice rifle. It's not a super-accurate one, however.
The two-piece bolt and non-match chamber work against it. The sub-minute 77-22 has not been built, except maybe by accident.
Did you really think about that, before you typed it? "Two-piece bolt" and "non-match chamber" are terms that apply to the great majority of the bolt action .22 LR rifles on the market - not just the 77/22.
Two-piece bolts and/or "non-match chambers" are found in most or all models from Marlin, Savage, Winchester, CZ, Remington, and Kimber. (And I'm sure I missed a few manufacturers.)
