Fairly simple for me...
I just keep that re-formed brass separate and in its own marked box.
Happily I only have one rifle for which I have to 'make' brass.
I have a pile of .45 Auto Rim. Some of the cases are loaded light for a Webley (I didn't cut it, it was that way when I found it!) Those cases stay in their own boxes with clear markings as well.
(The bulk get used in a Model 25 S&W revolver. A 255 SWC at 800 fps +/- is rather serious.)
