Well, I got to shoot it and it was surprisingly accurate. Once I fired about 20 rounds to get it sighted-in at 25 yds., I was able to get a ten-shot group that I could cover with a nickel (MAYBE even a dime). HOWEVER, the fact that the barrelled action could be moved (wobbled) front to rear ever so slightly, but very obviously bothered me so I decided to try a "quick and dirty" glass bed job (JUST
ON THE REAR) of the action behind the trigger group. There is a small shelf which sorta 'slips' in between an area of the trigger group; so I
guessed if I could build up the top and bottom of that shelf, it would keep the action stable and not require me to mess with the barrel channel. I wrapped one piece of masking tape around the bottom of the barrel, about 2-4 (?) inches in front of where it goes into the receiver (making sure not to get near the screws and block etc). Preparation required plugging all holes and seams in the back of the trigger group with play-dough. Then careful application of release agent. Because it's a plastic (polymer) stock, glass bed won't adhere, so I had to drill small holes
at opposing angles to create a mechanical lock of the glass. I also decided to do the top part of the shelf first and let it harden/cure before attempting the lower half. After completing both the top and bottom, it appears to have eliminated the "wobble" completely AND the (heavy) barrel of my 10/22 is still free floating (albeit tightly...only can slip a single dollar bill down the channel). It may be a few weeks before it will be warm enough for me to test for accuracy again, but logic says that it won't be any worse then before I started. The work is NOT pretty, but it's all inside so you can't see it. Here are two pics.
