I shoot a fair amount of .22LR and .17HMR, especially now with the scarcity of other calibers. I always collect my casings when I'm done shooting, I believe in being a responsible steward of the land. I keep my centerfire casings to be reloaded, but I know rimfire can't be reloaded. Any suggestions as to what to do withe the brass? Just regular recycle? Trash? I don't like the idea of throwing brass in a landfill.
Actually, you can reload rimfire ammo, it just takes time and one of these kits.
