American Pioneer powder is ok for use in cap guns, but not for flint locks. It produces lower vel. than tripple seven. For general all around use I prefer Tripple Seven as I can shoot in not only my Knight inline rifle, but also my TC Hawken cap locks as well. Yes same can be said for American Pioneer, but I like the accuracy and higher vel I get with Tripple Seven. Your rifle may prefer the American Pioneer. Warning, when using American Pioneer, you still need to clean your rifle. A lot of guys in the gun stores are telling people they don't have to clean their rifle when using American Pioneer, not true. Says so right on the bottle if you read the fine print.
