All my black powder loading is done by volume not weight If you want to actually weigh the powder after the case is full that’s up to you. As long as that case holds the same and compressed the same your good to go.

That's all well and good, you stated as a definitive that "black powder is done by volume not weight" which is a popular misconception and one I think worth correcting. I'm not trying to be pedantic just making sure current/future readers are aware. Grain is an avoirdupois system expression of mass as opposed to a volumetric measurement like the cubic inch. If a powder measure is marked to "50 grains" this is an estimated average volume occupied by whatever powder(s) the person marking it used as their reference. Goex FFG is a different density than Swiss FFG and they will take up different amounts of volume for the same mass. There is no industry agreed upon standard for granulation size, density, or burn rate.

As to OPs question, what version of the case are you using? 455 MK II will hold less than .476 or 455 MK I. I would suggest trying FFFG first though experimenting with FFG won't harm anything.
 
I’m using modern new off the shelf 455 brass I think it’s referred to as the mark two brass I can’t remember and yes, my revolvers will chamber it
