WOW!!! What a deal.
I have had my blued 10/22 T for a couple years. It is topped with a B&L Elite 3000 (SWFA rocks). It has been delivering accuracy like you describe since day one. I have played with the idea of replacing the hammer components with either Volquartsen or Power Custom. If you don't mind dropping $200 you can pick up the Trigger Guard 2000 from Volquartsen (price never changes, even at gun shows it seems). It has the automatic bolt release, extended mag release, and all match trigger/sear/hammer components. Really nice, but I have heard you can get the same trigger pull for $60 worth of parts if you don't mind doing the install yourself. It is supposed to be easy.
For ammo try the Remington 22 Target ($4/100 @ Wally World), it is pretty good without paying match price.
