A large bomb, plus four large steel pipes used in construction to make four small, underpowered bullets. If the pipes are that big, this should be a rocket launcher. If we're using nobelisk, these should be explosive rounds. We should have mag sizes of 30, same damage, but made with gunpowder and screws or something... Then perhaps a different type of ammo, high-velocity rounds, that use nobelisk and steel pipes, where you only have 10 per mag, but do way more damage.
