I have a little trick in loading the FPB bullets. They run big, so you need a loose bore for them to load easy.
So, what I do is use the barrel to size them. With the breech plug removed start the bullets down the barrel upside down. (point down) Just push them all the way down, and out the barrel. You've now sized them, but also etched the rifling in them. When you now load them to shoot start them lightly, and turn the bullet slowly until you feel the etching on the bullet line up with the rifling in the barrel. You'll feel the bullet drop it slightly. it's very subtle, so don't try to force it. Once you feel it start just push them down. Works for me.
Just size up the whole pack of bullets at once, and your done with that process. They're ready to shoot when you need them.
