The 500 Jeffery , with his slight rebated rim , in a magnum action is not the problem , whereby by shooting a elefant with 2 shots in the heart there after the trackers gave me 2 shells back --- and a cartridge , loosed by quickly reloading !

By the 11,2x72 i push with my thumb on the cartridges in the magazine by reloading ! The rim of this cartridge is very rebated !

Very interesting all this old cartridges ! You can see where were the problems in the golden age of the safaris !
