The original loading for that round would be closer to 53-55 grains of FFG, I would think, as the "55" designates the powder charge.
I don't think I would use FFG, but give Mooncoon a PM, he messes with the 38/55 and 38/56 A LOT!!
I have seen him knock over the 5oo meter rams at our range with his little rolling block, and I tell ya, it is impressive, considering the short barrel and time of flight, not to mention the wind!

Ultimately the important thing is getting a uniform burn rate and uniform velocities with whatever load you are using. In small cases such as the 38-55 it seems to me logical to use 3F but it is also logical to try 2 F and compare the results not for velocity but for accuracy. A great deal of the trick in long range shooting is in accurately knowing your sight settings and using an accurate load as opposed to getting the highest velocity possible.
I have a 38-55 trapdoor springfield but have only had time to fire a few shots with it. The 3F black loads seemed to be reasonably accurate as best I can recall. While the 55 refers to the load, it also applies to baloon head cases and at a guess you probably won't get more than 45 or 50 grains in a modern case depending how deeply you seat the bullet.
I would also suggest using soft bullets so they upset into the bore and spg or similar lube with black powder. If you are using the gun in cowboy type shooting it is also probably wise to pour some water down the barrel and then a pull a bronze brush through with a pull cord, every 10 shots or so to try to prevent or reduce leading.

I guess should have been a bit more clear on the capacity part!
