Well, my most accurate .22 is my bolt action Anschutz that I compete in prone and 3-P matches with....then again at about $3,000 it better be pretty accurate. <img src="images/graemlins/smirk.gif" alt="" />
Out of my semi's I like my Ruger 10/22. The fun thing about 10/22's is there are thousands of aftermarket parts and accessories you can get for them. I think it is possible to build a Ruger 10/22 without ever buying a Ruger part. <img src="images/graemlins/grin.gif" alt="" />
In ammo I like to stick to Winchester XT22LR for practice and for competition I use Eley Match Xtra, Eley Match EPS, or RWS Target rifle depending what that particular rifle likes.
