.585 Gehringer

The .585 Gehringer is an elephant gun cartridge of the .577 bolt action wildcat family. It was designed over several years by Karl Gehringer, member of the Australian wrestling team during service in the Australian Armed Forces. Like most elephant guns the purpose was stopping power on large dangerous game at close quarters. The test rifle was a CZ-550 .416 Rigby fitted with a .577 Tobler Barrel of 1:22 twist rate. A 2.8" Nyati reamer and 3.25" Bertram brass was used to create a unique case length of 3.06" and the rims were rebated to the original .416 Rigby boltface.

In 2001, Woodleigh 750gn softpoint and FMJ bullets were tested to 2,350 ft/s (720 m/s) as a suitable hunting load. Geoff McDonald of Woodleigh also provided a special run of 900gn softpoints for the rifle.
