Unless of course, if you include the line of
Ballistic Tip Bullets made by various companies such as Nosler, Hornady, Sierra, RWS, Geco, etc, etc. for the past 50 odd years!
The tumbling of a bullet on impact is not induced by the CoG being towards the rear of the bullet mass, it is induced by a Gyroscopic Effect, where a rotating mass which suddenly decellerates will twist on it's axis. This was also famously apparent in the US M16 rifle, which was described as an "insidious characteristic" of 5.56mm ammunition when introduced. After an outcry over it's "inhumanity" due to the severe wounds it caused (it's a war, go figure!), it was modified by reducing the rate of twist of the rifling in the barrel to reduce the rpm of the bullet in flight, which in turn reduced the tendency to tumble on decelleration of impact. It is certainly not a unique characteristic on the .303 Mk7 Ball Cartridge.
