I have the same rifle, and had the same experience as you the first time out. The difference with me was I cranked on that breech plug wrench that came with the rifle so hard, I broke it. Then the words really flew. Some easy tips for making sure that does not happen again.

I apply a good coating of CVA Slick Nipple and Breech Plug Grease. The Thompson Center stuff did not work for me. Also when your at the range shooting, every seven or ten shots, take your breech plug wrench and reach in there and twist that breech plug back and fourth. This will break the seizing that your experiencing. After I started following that routine, I have never had another problem with the rifle and breech plug seizing up.

Also get yourself a 8" socket extension and a 9/16th (or was it a 7/16th.. now I am not sure)deep socket. This will then allow you to reach in all the way from the back side of the breech and remove the nipple and breech plug with a simple socket set. This is especially helpful if you have a scope mounted on the rifle. Use your factory included breech plug wrench to twist the plug on the range or for an emergency in your possible bag.

That's a great shooting rifle you got there.
