When using muzzleloading firearms Fg, FFg, FFFg and g are examples of what? A, Different types or sizes of ammunition

B, Different granulation sizes of black powder

C, Different types of firing mechanisms

D, Different barrel types or lengths

B, Different granulation sizes of black powder

Explanation:

A muzzleloader firearm is a firearm that has a muzzle through which the propeller and the projectile is loaded from. For muzzleloader firearms,  Fg, FFg, FFFg and g are examples of Different granulation sizes of black powder. The number of F's represent how the black powder is grounded, g is the smoothest and is used for muzzleloading rifles of 45 caliber and smaller. FFG is less smooth and is used in muzzleloading rifles larger than 45 caliber while FG is the most coarse used in large bore shotguns.
