Dan,

Send it back with a detailed list of rounds fired, rounds failed, and ammo details. Call them to walk through it with CS, and get a shipping label.

But DO include a written explanation that covers the complaints in the box. There is not always a complete communication between the CS agent and the gunsmith. Gunsmith goes off the written list.

However, I would comment that my .22 Compact is picky. It is marginal with hollow point ammo, but runs great with CCI AR version.
