Am I understanding that you are shooting the cast at the .413 diameter or resizing down to .410 or .411 from .413?

I have never resized before. Does it strip the gas check in the process? Will new properly sized gas checks be needed?

Also, for those looking to order QC brass, I just tried to order 5 bags (100 total from Grafs). At checkout they only had four so guessing now they have none. May be worth a call to QC to let them know there is some demand. I plan to call tomorrow myself.
