That is for the 209 and I think you need a special striker. Call Thompson Center Arms if you can not find them. They sell all the things you would need to shoot 209. BUT I think if you're shooting loose Pyrodex RS, even with the #11 you will get good results.
This was after shooting 30 rounds that day. The rifle was so dirty, I had to clean the hammer striker and breech area just to make the rifle fire. But I shoot alot of Goex.
