Re: Have 600 to spend on 10/22 any sugg
I have had success with a tactical solutions barrel ($200) a bell and carlson Target/varmint stock ($200) and hornet trigger group at 2.5# ($90). I kept the stock receiver, bolt, guide spring, buffer pins, and v-block. Beyond that any additional parts I would buy wouldn't increase accuracy enough to justify the price. I also bought a rimfire technologies adjustable v-block to try and free float the barrel: didn't work.
What I have found is that the stock Ruger 10/22 receiver has limits. Due to attaching to the stock in only one place there is a pivot point for your barrelled action which usually causes your barrel to touch the stock. To maximize accuracy you can bed the barrel and float the receiver (no personal experience), drill bolt holes through the receiver the size and location of pins in the internals (no experience, seems to allow the barrel to be floated, but messes with the look with bolts sticking through the side of the receiver), use pressure pads in the barrel channel (works for me).
All in all there are a million things you CAN do, but the stock, barrel, and trigger should be priorities in my opinion. If you're still not satisfied you can try the other more involved methods with detailed instructions on rimfirecentral.com
