Hey guys, I bought some once fired brass recently. Found a handful that look darker, like gunmetal. They aren't steel. Some odd head stamp, characters not English. But I have some with same stamp that are plain brass.

Sarge

My first thought is a really harsh wet tumbling solution. I have turned some pretty dark.

Absocold

Gravoxide, liver of sulpfur and Brass Black by Birchwood Casey all work. Thoroughly degrease for best results.

Blackland soil will stain them like that and I have not seen any problems shooting them as long as you don't mind shooting stained brass.

Absocold

Everything mentioned so far involves a chemical change to the brass which will weaken it to some small degree. Hell, just looking at brass weakens it. You have to decide if it's worth it.

GrumpyOne

You could use DyeKem to stain it...hell maybe even something like water based walnut wood stain..
