Well, the way I learned, black powder is graded by the size of the granules as Fg. FFg, FFFg, and FFFFg. (The more F’s, the finer the granules.) FFg and FFFg are the grades commonly used for pistols, and longarms. As a general rule, FFg or “2F” is for bores larger than .50-caliber. and FFFg or “3F” is for bore sizes of .50-caliber or less. FFFFg or "4F" being of extra-fine grain is used for priming the flintlock pan for it ignites more readily. 4F powder is also more susceptible to moisture, so in wet weather it may be of conccrn.
Triple 7 is a black powder substitute that can be used in more modern in-line muzzleloaders, easier clean-up, and faster burning.

make sure you know which grade of powder your firearm should be using. You wouldn't want to replace 90grains of ff with 90grains of fff.
