From the reports it looks to me like they have came up with a great muzzleloader to hunt with. I would not have thought that the different shotgun primers would have made much of a difference.
I would guess we are talking 100% ignition with 209's and the in line design? I can see no reason it would not be completely reliable, just like a Contender, and maby more so. I have had my Contender snap a couple times with shells not sized completely.
I can see one in my future.
