I have about 55 pieces of the short Hornady 45-70 brass. I use it but it is annoying as hell because every time I go through my 45-70 brass I keep double and triple checking that one doesn't end up with the regular 45-70 brass. I was thinking about drilling an indent on the base or grinding a notch or two on the rim. These I only use for low power plinking rounds so it is not like they get exposed to a whole lot of pressure.
Is there a more sensible way to mark these?
