I find it truly amazing that out of the 52 views that this post has had since I created it that nobody has a 209 primer muzzleloader and could tell me how their primers fit. I have since shot mine and know the answer to my own questions. I joined this forum after seeing how people seemed to reply to others questions but I guess not. Maybe I'm not in the loop. I'll find another forum for hunting and gear discussions. Good luck hunting.
