Jim, I'm afraid the threaded barrel change on the new Rugers will just make it that much harder to get one that shoots, at least with the old system you could make a simple barrel change and have a barrel made to match grade tolerances, now we are at Rugers mercy to build an accurate 22lr sporter and I like You have owned several 77/22's and none were what I consider good shooters, so I have little faith in Ruger tightening up tolerances in these latest rifles, I will be actively searching for a NIB old model 77/22 which I have had zero luck in finding so far..............Hillbilly.
