I am going to have to get me one of them to,I use the long T/C at the range because it lengths the ram rod been luck haven' t broken one yet.
I have thought about the 209 primers before,in my ruger I have tried up to 120 grs of clean shot,pyrodex, and only went to 110 grs of T-7, it uses the #11 caps and have never had a failure to fire off yet.My thoughts is that the 209 is more hype than need,and I think when using the #11 cap in a bolt action there is less fouling in the chamber so I think some of the blow back is coming from the primer,thats just my observation.
Think you are right about them getting together and making a primer just for muzzleloaders.I just picked up 2 boxes of the Win 209' s but it say for shotshells,maybe someone on here knows more about the ones Mike was talking about that said for muzzleloaders.
