by the way
By the way, maybe I'm crazy, but what I do is put all my new live rounds in plastic boxes (Berry's Bullets makes GREAT boxes!), and visually inspect them all, one by one, as I am human and have made the same error as you (backwards primer).
Then, I take a blue Sharpie pen and run it over all the backs of the rounds...it helps me quickly determine which are mine at the range when I'm picking them up! The ink comes off when I polish them before reloading, but it's easy to do again.
