No experience with that gun, but have experience with Blackhorn 209 powder.
Any standard shotshell primer should work, I use Winchester. The manufacturer claims that better ignition can be had with "magnum" primers from CCI or Federal, but I'm aware of a bunch of guys from the modern muzzleloader site that have no problem using the standard primers. IMHO the key is a tight fitting bullet/sabot and you will have success.
Winchester primers are usually the longest so in many guns they seal better and typically produce less blow back into the action of the muzzleloader, (cleaner is better!

).
