Ok, it's target practice rounds as stated earlier. However it does have live high explosive components and should be treated with the same respect as HE, Frag, etc, etc,....The hazard is not from any explosive or incendiary filler but from the electrically initiated primers. What that means is that a good static build up will cause the primer to fire. Since the round is sealed there is a very good chance the powder will ignite. Pressure will build up. Since the brass case is not encased in a solid steel barrel, the brass case will fragment like a grenade. Contact your local police and tell them you found some abandoned military ordnance. Don't touch it. Mark the area and tell them you'll take them to it. There use to be some pretty gory photos of adventurous fellows who had tried to pop the primers and ended up without hands, eyes etc. Yeah it doesn't sound dangerous but it can be, if improperly handled. Get your local military EOD guys out to pick it up and while you're at it to them what a great job they've been doing in the "Stans!
