I have No Clue about the TC, but on some of the CVA's like My ACCURA all you do is unscrew it and pull out the Firing Pin. The Firing Pin will have a Small Spring around it, dont lose it and make sure you put it back in the right way. I like this as even though 209 Primers are Non Corrosive, BP is and depending what kind of BP you use and if there's even just a small amount of Blow Back it will get into the Firing Pin and eventually cause it to stick, and you dont want that.
Im sure a TC Shooter will chime in......
