I am sure that most know that the nitro .303 MkVII loading was meant to be a "British" duplicate of the 7mm Mauser round used by the Boers against us in South Africa. Imitation being the result of lessons learned in that conflict.
A 175 grain bullet at 2,500fps would work fine! I think that both Speer and Hornady offer that weight.
Actually, Frikkie van der Merwe was stuck with the same FMJRN configuration Tommy Atkins carried. The .303 spitzer pointed bullets were specifically developed to compete with German advances in the form of the 7.92x57 154 gr Spitzer of c.1905.
The .303 MKVII loading was introduced in March, 1910, then improved and standarized November, 1910. This loading was used for many years with MDT 5-2 powder {AKA in common terms; "Cordite"}. Nitrocellulose was approved May, 1916 and it also continued in production for many years under the sobriquet MKVII.z.
