Yep, 30grs in my .40 and 80grs FFF in my .54...
Back in the 60s and 70s the theory was use FFF in .45 and below and FF in .50 and above...It's not necessary to do that and since black powder leaves a fouling residue you can cut from say 100grs FF in a .54 to 80grs and have a cleaner burning load, leave less residue in the barrel and get about the same velocities...
