Research notes

The 375 A-Square is based on a 378 Weatherby case slightly shortened and the shoulder moved slightly forward and with a 35° shoulder as opposed to the double radius of the 378 WBY. It was developed around 1975 by the A-Square Company and attempted to duplicate 378 Weatherby ballistics on a cartridge with the same OAL as the 375 H&H Magnum.
