I'm a beginning collector of 50 BMG cartridges and would like to know what the color codes mean for the various projectiles. Besides normal curiosity, I've cut open some AP projectiles (black) to get the steel core out. It might ruin my day to attempt cutting open an incendiary or tracer by mistake.
I've also noticed that the very tip of the AP steel core is covered by a layer of some soft grey metal. I was wondering what the metal is and its purpose.
