When I was a new recruit in 1981, the Drills used ammo can's filled with water.
An M16A1 put nice leaking holes in the cans, but the M60 fired just a 2 or 3 round burst and the can pretty much exploded popping the lid open and water bursting into the air to about 10 feet or so.
It had it's own dramatic appeal.
