I got my 77-22 ~30 years ago from a gun store that was going out out of business. 50% off list...$160 OTD!
Over the years, I had a gunsmith buddy do a trigger job...$7.50, then added a scope...Weaver 4X Rimfire
Classic (still going strong!) then I did a "first ever" glass bedding job.
Got a potful of magazines...the tales of 10-22 and 77-22 mags not being compatible don't seem to hold water.YMMV
As far as bolt shimming goes, I ordered some shims to "tighten" the bolt halves from Lance at Triggershims.com. The thinnest shim was waaay too tight...the bolt would barely close! I read that some folks grind a larger diameter pin that holds the bolt halves together, soooo...I figured to measure my bolt pin, then order a half-dozen from Mother Ruger, and use biggest one to replace the original. It seemed to work!
Getting that little pin back in is a real bear, if you don't pay attention to the way the flat side positioned!
Anyway, I guess I took the long way around to say I really like mine. Very accurate, and it will shoot right along side my CZ 455.
From the picture, it looks like you did good!
