just shot my new 15-22 yesterday. Used Winchester (copper plated I think) ammo. Had 2 FTF in the first 25 rounds and that was it. The next bizzillion rounds fired without issue.

For all those that are having issues I suggest you call S&W, send the rifle back for service and make the request for the actual person who services the firearm to give you a call so you can find out what they did and let them know you want to make sure the problem you had is fully understood by the technition.

S&W is a great company and supports the products they sell. Not sure if they'll do it but it will let them know you expect the job to be done right the first time (I've done this with other products and had preety good response).
