 History of the 30 Super Carry Cartridge:
 The 30 Super Carry cartridge was introduced in mid to late 2021 by the Federal Cartridge Company and became available to the general public in the U.S.A. around late June 2022.
 The cartridge is designed for the concealed carry, smaller pistol market and its power is approximately between the 380 ACP and 9mm.
 The cartridge is 8mm (.313") and is lesser in diameter than the 9mm Luger (9x19mm) and should technically hold more cartridges per pistol magazine than the 9mm.
 The Federal Cartridge Company has high hopes for the caliber, but only time will tell.
 The bullet diameter is 8mm or .313", bullet weight is 100 to 115 gr., muzzle velocity is 1250 FSP, muzzle energy is 347 foot pounds per square inch, case length is .827", maximum chamber pressure is 50,000 PSI.
