At left is an M1903, at right an M1924. A ring was added to the M1924 and subsequent MS of prewar manufacture ('High Velocity' in the '39 Stoeger) and throughout postwar production. The ring eliminated the need for such careful feeding, as they held the cartridges at proper clearance and alignment at the shoulder. To ensure smooth and effortless feeding of the M1903 (6.5X54), M1905 (9X56), M1908 (8X56), or M1910 (9.5X57), obtain or load cartridges as close as possible to the original DWM or Eley specifications.
