What is the strongest gun in the world
Elephant gun for a hand held gun. Mounted weapons on battleships and armored military vehicles have more power (obviously).
Probably the ones on battleships.
You may want to narrow it down.Pistol, rifle, shotgun, assault rifle, mounted gun?
Possibly a 155mm artillery piece? That's the most powerful weapon I've ever worked with.
Smith & westen
maybe a mini gun?It's really good
