Well he answered the question correctly, but he could have added one thing in my opinion of course it was not implied in the question he may not do any pressure testing either.
Pyrodex is the most consistent burning of the volume measured powders under all conditions, this makes it much easier to achieve accuracy with especially in traditional guns, and while the residue is as corrosive as black powder it is also soft and easy to clean and most of the guns I have used it in you could get 3 to 7 accurate shots out of with out swabbing which makes it a good choice for hunting. With some powders every thing from the temperature to the moisture content of the air affects pressure and or residue and there is the hunting factor because where I live we have never been limited to one deer and there are boar ,bear bobcat and coyote to consider I may need that second or third shot in a hurry.
