Yes I have changed things on my 10/22. Green Mountain barrel, Volquartsen trigger parts, Magpul stock. I only shoot CCI standard velocity ammo because I did a bunch of ammo testing and the gun likes CCI the best.

Sorry to hear about your bore problems. IMO I think 10/22 barrels should be the first thing replaced. But CZ is the way to go.

If I was more serious about .22 shooting I would buy a CZ. Right now I am in a .243 mode, with an after market barrel, Macmillan stock and Vortex optics. I can get similar groups at 100 yds, with it, as I can with my Ruger at 25 yds.

I enjoy reloading, so the 243 is my choice of gun, as I enjoy reloading and shooting.
