The Xploderz XRanger 2000 shoots up to 85 feet and holds up to 500 rounds of ammo. The best thing about Xploderz water pellet guns is that you can literally grow your own ammo. Its H2grOw technology uses a polymer and water-based system that creates an ammo strong enough to fire huge distances and yet soft enough to disintegrate on impact. And it is environmentally sound, developed by the Department of Agriculture to help reduce water usage.
