 These soft-nosed and hollow-point bullets, while effective against human targets, had a tendency to shed the outer metal jacket upon firing; the latter occasionally stuck in the bore, causing a dangerous obstruction.The Hague Convention of 1899 later declared that use of expanding bullets against signatories of the convention was inhumane, and as a result the Mk III, Mk IV, and Mk V were withdrawn from active service.The remaining stocks (over 45 million rounds) were used for target practice.
