The 345 TK cartridge was developed and is being produced by a Russian company Techkrim from Izhevsk. This new 345 TK cartridge is legally certified in Russia as ‘smoothbore’ (“shotgun”) ammunition. New cartridge is made to emulate 9×19 Luger ammunition, and features rimless steel case 22 mm long, loaded with variety of jacketed or hollowpoint bullets 8.8mm in diameter, weighting about 7.5 – 9.5 gram, and muzzle velocity from 30 cm barrel of about 400-450 m/s. Cartridge overall length is compatible with 9×19 Luger magazines. Ballistics of the 345TK round is also similar to 9×19 Luger, with effective range from 30cm carbine barrel being about 100 meters, give or take. It is intended to be fired from nominally smoothbore barrels with Paradox or Lancaster type bore.
