Re: 10-22 upgrade
Actually there can be a lot of things done to a Ruger 10/22 to make them shoot better. However as with a lot of things now days it costs $$$ to achieve this.
I have built a few 10/22's for guys around here. To me there are a few things that are required to make a 10/22 shoot good.
To start with is the Barrel. I have had great results using Green Mountain Barrels. I feel they offer a really good barrel for the $$$ spent. I have built 4 10/22's (3 of which were set in a Nordic Components AR-22 Receiver Chassis with AR-15 Buttstocks, Pistol Grips and Free Float Tubes, and 1 that was in a Revolution Thumbhole Laminated Wood Stock) using Green Mountain 20" Fluted Stainless Steel Bull Barrels. To attach these barrels to the 10/22 Receiver I used the Tactical Solutions V Block that is designed to help eliminate barrel droop. As a side note I also milled off the bottom of the Tactical Solutions V Block so it does not protrude below the bottom of the 10/22 receiver, otherwise the Tactical Solutions V Block can hold the bottom of the 10/22 Receiver off of the stock.
All 4 of these 10/22's shoot way better than I thought a 10/22 could shoot.
I have done a few trigger jobs on 10/22's using either the Factory Parts (polished per instructions at Rimfire Central) and or using Volquartsen Target Hammers together with polishing. I have come to the conclusion that the best $100.00 spent is to send the trigger group to TT Shooter for one of his Precision Trigger Jobs.
Next up would be bedding the receiver and or free floating the barrel. With the Nordic Components AR-22 Receiver Chassis the Barrels are totally free floated. On the Laminated Wood Stocks I only free float the front portion of the barrels approximately starting 2" to 3" in front of the V Block and floating the barrel from that point forward.
I have also had the headspace set on my 10/22 Bolts via milling off the front of the bolt face to get the recess for the cartridge head at the proper depth in the bolt face. I also chamfer and polish the lower rear surface of the bolt to provide smoother cycling of the bolt with Standard Velocity Ammo (I also add a Tuffer Buffer Recoil Buffer in conjunction with the Bolt Chamfering). Lastly I have had my bolts drilled and pinned to keep the firing pin from riding up as the firing pin strikes the rim of the cartridge.
This is just one of the Ruger / Nordic 10/22's I have built.

Good luck with your project.
