Recently I came across the DAA shell casings marking system which made me think I needed something a bit more fun. I’d like to emblazon my shell casings g with a vulgarity the “F-word” so that upon emptying a magazine I can truly say I’ve no more “F’s” to give. I’m leaning toward laser marking, meaning I would apply a thin film and the laser would remove the film in the desired shape leaving the brass in etched. I’ve also been trying to think of a reusable stencil or stamp but can’t figure out a practical way of doing thousand of casings with any quickness. Thoughts and suggestions welcomed.
