.600 BBR

The .600 Big Bore Revolver (.600 BBR for short) is a fictitious firearms cartridge custom-made for use in the infamous revolver known as "The Leviathan".

Design Details
The casing is based on the .600 Nitro Express hunting rifle cartridge, and shortened to about less than a quarter of the original 3-inch case length. This is done so that as to have a lower propellant capacity for lesser recoil, but the propellant loads are specified to ensure that it has enough muzzle velocity and power to pack a sufficient wallop. It uses a variety of projectiles, with the propellant loads meticulously adjusted for each projectile type.

Loads
More to be added
 * Std - Standard load with an un-jacketed lead bullet. Has a sufficient propellant amount to ensure that its muzzle velocity doesn't get too high as to melt it in the Leviathan's barrel.
 * FMJ - A load using a jacketed projectile.
 * Manstopper - A self-defensive load using a lead bullet with a wide hollow point designed to expand on impact.
