The "standard" hunting load for .54 cal would typically be 110 grains of FFF or FF (I use FFF) and a patched round ball. This is 110 grains by VOLUME, not weight. Grains have two measurements, just like ounces; Volume and weight. A 64 oz quart of milk does not weigh 64 oz, and 110 grains of FFF does not weigh 110 grains. You can go a lot higher, but you don't gain much. For plinking loads, you could drop waaaay down to the 50 grain range. Anywhere that sells black powder or BP substitutes will also have a simple brass powder measure to measure it with.
