Oh, all right.
I know a guy who is all into purple. He shows up in classes wearing purple, has purple mags, purple on his guns and he's plenty competent in their use. I gave him a purple ammo can and turned him onto Winchester's purple cased training ammo, which he bought a couple cases. Maybe it was him you saw, but I doubt it.
My lady is obsessed with purple....i now need to find this ammo, thanks!
