What I should have said is reloaded, not fired, which could explain this

If I have different rifles or barrels in the same Cartridge I will mark the brass like that or different cartridges using the same head stamped brass

A recent example is 6-284, 6.5-284 & 284 all using Lapua 6.5-284 head stamped brass
