I'm an altoid addict. The tins have a million uses, but eventually all your uses are covered. Now what to do with the empties? Shoot em! They're a great reactive target, they're tough, and they make some noise when hit. At 50yds they're a tough target. Don't throw them out until you put some holes in them
Flatten out one section of a bottle cap lip and stand up on a bar magnet.They really go flying when you hit them, but pretty difficult ti find in the grass.........
