I'm doing some inventory of supplies. Here is my dumb question of the day. How many average pan primes can nearly 4# of FFFFg powder do? It's actually 3# 14.6 ounces net weight. My pan primer is a very small bag flask (a Philadelphia model) and I just dump what looks to be appropriate for my various flintlocks (45 to musket size). I'm ordering powder and not sure on ffffg needs. I will say not knowing this is 100% my fault as like I said I just disperse what 'looks good' and have no real clue as to how much in a technical sense.
