These days, I use Pyrodex or BP for hunting in my percussion rifles/shotguns, primarily based on which one that I can FIND at a "less than highway robbery" price. - As I'm primarily a BP HUNTER, HC/PC is unimportant.
(Neither is easy to find in south TX & both work OK in my hunting guns. - My .58caliber Zouave is singularly UNFINICKY with either propellant.)
IF I was a flintlock hunter, I wouldn't use Pyrodex, as it simply isn't suitable in "rock-locks".
(Now, if I could just find musket or #11 caps at a decent price, I'd be "a HAPPY camper"!)
