Can’t wait to be able to get some of this from Glow Ammo. It’s a “tracer” like kind of technology that is both chemically and biologically safe unlike traditional tracers. It’s a sticker that you’d stick at the bottom of your bullet just before you reload it. Once shot, the heat (I believe) causes the sticker to glow thus making it look like a tracer going downrange. here’s a video of how it works with .45 ACP ammo :
Watch this space, I’m definitely going to shoot an IDPA match with this and post videos.
