DR in 500 Jeffery, under no circumstances !

The cartridge 500 Jeffery is for use in a bolt action rifle, for the real aficionados only with a Mauser action, Magnum if possible. Due to its design with a rebated rim, it is not suitable for a DR anyway.

There is a good alternative, the cartridge 577/500 Hartmann & Weiss.
