so i figured i would see how they worked as ammo and bought them.these things are great if you have a 3/4 inch barrel I was shooting at a can full of water mounted on an old wood later and i was kind of off and instead of hitting the can it went strait through the sheet and the fence post behind it.I would recommend trying these out there only a dollar for a pack of 3 and they can be reused if you can find them.
