I've tried them in a 22/45, 10" contender match and 10/22. In all cases accuracy was worse then cheap bulk ammo. I did crono them in the 10/22, and velocity averaged 1700 fps as claimed. <P>I've also tested the SSS ammo, and it was suprisingly accurate in the match contender, though on par with other ammo in the other guns. I never bothered to chrono it, it is noticably quiter in the rifles.
