|The .500 Jeffery was developed by Schuler, in Germany, under the European designation
12.7x70mm Schuler or .500 Schuler and introduced around 1920 by the August Schuler Company
in Germany for the Schuler for bolt-action rifles. Please note this rebated rimless cartridge.
Similar to the .505 Gibbs but with a shorter case, the .500 Jeffery produces higher velocities and
energies up to 2400 feet per second and 6800 foot pounds per square inch with a 535 grain projectile.
This cartridge will stop any big game on the planet.
