7.7 x 56R : [IND] Cartridge, SA, Ball, .303-inch, Mk 6
Ammunition round, case with long rounded bullet.
While the search for more satisfactory terminal ballistics than those achieved by the round nosed .303 Mark II had resulted in hollow point designs (Marks II Special, III, IV and V, of which the Mark V was satisfactory), growing concern over the risk of their contravening the St Petersburg Declaration or Hague Convention resulted in a return to the Mark II form in 1904, by which point consideration was already being given to a lighter spitzer bullet design that culminated in the Mark VII. The Mark VI is essentially the Mark II round, but the bullet has a slightly thinner jacket. This specimen is one of a miscellaneous group of small arms ammunition picked up at Gallipoli by Mr. A. Riley, whose diaries and papers are held in the Department of Documents.
