The Heym SR21 in 9.3x62mm is a German bolt-action dangerous-game hunting rifle in the cartridge developed by Otto Bock in 1905 as a rimless dangerous-game round for Mauser 98 actions. The 9.3x62mm delivers 4,300 ft-lbs of energy with a 286-grain bullet at 2,360 fps — legally adequate for African dangerous game including the Big Five in most jurisdictions. The Heym SR21 action's controlled-round-feed, double-square-bridge receiver, and double-set trigger represent traditional German hunting rifle features applied to a modern production rifle.
