I recently bought one of those too and it's a HUGE piece of shyt. In fact, it's back with Ruger right now and I just got notified they'll be replacing it. I guess it was too much of a train wreck to be worth fixing.
I have two of these rifles, 17hmr and a 22wmr but haven't put but a few rounds through them and have had no issues. Would you mind sending me a pm and let me know what kind of issues you were having?
