First off, I'll never be without a 10/22. It's too much fun and boringly reliable. I have installed an after-market trigger and replaced the wood stock with a Hogue synthetic. However, when my SIL gave me his Model 60 (18-round tube with hold-open feature), I shot the center of a target out with Velocitors, which was the first (and to-date the only ammo I've tried in it). No after-market anything but this Model 60 can shoot.
