Thanks for the links Blackwolfe. I do check in with RFC now and then and they are a great resource for all things RF.
I am a great proponent of free floating barrels. This particular one is just seated ever so slightly in the stock. If accuracy is going to be affected by the stock then it will change with the weather. Better to find out now than say go to a match in the late fall and discover I can't hit anything.
It is a more recent vintage with plastic parts. The trigger is okay, not great. If I can shoot MOA groups with it, then I'm not going to mess with it. It is by far the best of about 6 different .22lr I've ever owned including an early model (1980s) 10/22.
I give Ruger a 2 thumbs up for the improvements in accuracy they've made to the 10/xx and the Mini-xx line recently.
