.505 Gibbs

[2] While the .505 Gibbs has a greater case capacity than most modern cartridges, it is loaded to lower pressures.

[3] As .505 Gibbs was intended for hunting dangerous game in tropical environments, and due to the temperature sensitivity of cordite, the lower pressures provide a greater safety and reliability margin.

[5] Doumoulin Herstal SA of Belgium offers the cartridge in their White Hunter model.

[6] As of 2019, Federal, Kynoch, Norma, and Swift are offering factory loaded ammunition in .505 Gibbs.

The large volume was required as the cartridge was designed to burn cordite as its propellant.

The .505 Gibbs is a niche cartridge designed for hunting heavy, thick-skinned dangerous game animals, such as cape buffalo, elephant, and rhino.
