An elephant gun is any kind of gun that either used black powder bullets or was used to hunt large animals like elephants, buffaloes, and others.
Many of these types of guns are rifles.
Powers and Stats
Name: Elephant Gun
Origin: Real Life
Classification: Large Caliber Hunting Rifle
Wielders: Big-game hunters during the 19th and early 20th centuries, few people in the present (mostly collectors, given the legal protections on elephants).
Attack Potency: Wall level (Firepower for a .700 Nitro Express rifle is about 12,100 joules. A 4-bore rifle can match or exceed the firepower of the .700 NE. A 2-Bore rifle can exceed 23,000 joules. The .950 JDJ, while probably never actually used to hunt elephants can be classified as an elephant gun cartridge, and can hit as hard as 52,450 joules.)
Speed: Supersonic (A fired .700 Nitro Express can go around 610 m/s. The 4-bore and 2-bore are typically slower at 400–550 m/s, depending on charge weight and barrel length. The .950 JDJ can reach 670 m/s.)
Range: Generally close range, no more than a few dozen meters for accurate kill strikes on big game.
