The .375 Swiss P or 9.5×70mmRB, designated 375 Swiss P by the C.I.P., is a rebated rim, bottleneck, centerfire rifle cartridge. It was developed during the late 2010s as a high-powered, long-range cartridge for military snipers and the law enforcement sector.[2] The loaded cartridge is 14.93 mm (0.588 in) in diameter (rim) and 93.5 mm (3.68 in) long. It can penetrate better-than-standard military body armor and has a maximum supersonic range of about 1,600 metres (1,750 yd) with C.I.P. conform FMJ factory ammunition at sea level conditions. Muzzle velocity is dependent on barrel length, seating depth, and powder charge, and varies from 860 to 870 m/s (2,800 to 2,900 ft/s) for commercial loads with 22.7-gram (350 gr) bullets, which corresponds to about 8,500 J (6,300 ft⋅lbf) of muzzle energy.
