Can a man with an average Super Soaker vs a man with a heavy clip size rapid fire Nerf gun result in either dying. If so who wins.

Unlimited ammo for each, but the Super Soaker guy has to pump it back up after each shot. Fight takes place on an open field with some boulders around as cover. They are not able to hurt each other with anything other than their projectiles. Both people are physically identical and average in every way. The fight takes as long as it needs.
