https://stream.echo6.co/videos/watch/65bc8cab-9cc1-4860-8723-2a9151b015cc Carl Bertil Johansson is a Swedish small arms designer who has a wide range of experience. The project he is best known for is his 6.5x25mm CBJ cartridge, which necks 9x19mm down to 6.5mm and then uses a plastic and aluminum sabot to fire a 4mm hardened tungsten penetrator. This provides really exceptional penetration, cleanly defeating all manner of allegedly rifle-proof armor. The reason is that in addition to the small hardened penetrator, the cartridge develops really high velocity - 2400fps from a pistol and 2800+ fps from an SMG. The case head and overall length are identical to 9x19mm, so the round requires only a replacement barrel to operate in 9mm firearms. In addition to the APDS round, the company (CBJ Tech Ab) also makes a subsonic AP round, a solid brass duty round, and a frangible round.
