3. The question of who chambered it first stirs up some controversy


Not really,...The BRITS did,....called it the .450 x 3 1/4 Express or some such.
SAME case, lighter bullets, lazier (and sane) twist rates, single and double guns, some VERY high end "Majarajah Class".
...popular in India and Africa for a BRIEF while,...and a source of grief when Cordite and White Powder rounds in the same dimensional spec. came along.
