I looked in my Handloader's Manual Of Cartridge Conversions, and here is what I found.
.375/303 Westley Richards Express.
200 Gr Round nose Bullet.
53 Grains IMR 4320.
For 2700 F.P.S.
Now it says that it is made by converting a 7x65R Brenneke, or .405 Win BASIC brass, but not the .303 British, so I cant be sure if this is exactly the cartridge you want, but hope this helps.
