Congradulations, I saw your annoucement on the Upland site was going to congrad you there. Got interupted. We bought one when they first came out, can't even remember how many years ago. Anyway we bought it for teaching Hunter Safety, I wouldn't even try and guess how many rounds have gone through it. It has never ever given a problem yet. Have lent it out to some first time turkey hunters, just changed tubes, and they wind up buying one. Great gun, enjoy it.
