yrunvs, I guess I didn't make my point very well. If you want really good accuracy, you need to start with a better rifle than a factory 10/22. As I noted above, "The best scope in the world cannot deliver better accuracy than the gun is capable of."
I really enjoy 10/22s .... got 4 of them but I didn't buy them for benchrest accuracy, except for my above build. They are plinkers and do a very good job of it. It's hard to beat a day at the farm with the grandkids, a brick of 22s, and a couple 10/22s.
My first 10/22 Carbine was made in 1974. I still have it and it still shoots great.
The next one is my favorite ... a Mannlicher stainless. I've had several different scopes on this gun to include a $700 4.5~14X Leupold VX III and it wouldn't group any better than with a $100 Nikon 2~7x at 50 yards. My granddaughter has laid claim to this gun and prefers iron sights.
Last is my TD stainless, still a fun gun. It has a Ruger 4x32mm scope and kills bean cans @ 50 yards every time:
