The round nose loads won't apply because the flat nose will have to seat deeper. That raises pressure considerably. I don't have any of those, but hold one next to the case and measure how much of it will be inside the case. I can use QuickLOAD to estimate the charge adjustment as compared to a lead round nose bullets seated to SAAMI cartridge maximum.

The plated bullets don't need to be as wide as lead because gas blowby doesn't affect them as much. They are not as hard as jacketed bullets, however, so their start pressure is lower, like a lead bullet.
