The 30-357 AeT was developed around 2001 by Italian gun writer Nicola Bandini, who named the cartridge after the Italian gun magazine “Armi e Tiro” hence the name .30-357 AeT. It is bases on the 357 Magnum case necked down to .30cal. The logo on the case is FAP (Fratelli Pietta) inside a diamond and the cases were made for them by Lapua. The company was going to offer this cartridge in a line of replica Colt Peacemaker revolvers.
