Close

The 9.3×74mmR is of a rimmed, bottleneck design and uses a .366-inch (9.3 mm) diameter bullet, usually weighing 286-grain (18.5 g). According to Hornady, at this weight the velocity is 2,362.20 ft/s (720.00 m/s) and energy is 3,536 ft⋅lbf (4,794 J). This cartridge is used for hunting medium to large game animals and is very popular in Europe for wild boar. It remains a popular cartridge for African safari hunting in countries with more German influence like Namibia, favored as a continental alternative to the more popular .375 H&H Magnum.^{[citation needed]} Outside Europe, Ruger formerly produced the Ruger No. 1 falling-block rifle in this cartridge, but have currently discontinued production of any rifles in this caliber.^[4]

The cartridge is also a very popular chambering for double rifles and combination guns, including the famous M30 Luftwaffe Drilling manufactured by J.P. Sauer & Sohn. It was primarily used by downed German pilots as a survival weapon for hunting and self-defense purposes, while serving in the North African campaign during World War II.^{[citation needed]}
