By the way, PJB, first thing I do with a Kodiak double is swap out the nipples for the larger musket cap nipples. My theory -- and it is just a wild-ass guess -- is that the much bigger and hotter spark from the easier-to-handle musket cap gives a faster and cleaner burn no matter what powder you are using. I used Goex Fg and FFg in the last Kodiak .72 I had, and when the new one arrives next week I look forward to trying the Swiss I have since stashed. I use both RWS and CCI musket caps. Haven't tried to sort out the difference.
