=== Cordite (Mk I) and Cordite MD ===
The original Abel-Dewar formulation was soon superseded, as it caused excessive [[gun barrel]] erosion. It has since become known as ''Cordite Mk I''.{{Citation needed|date=January 2021}}

The composition of cordite was changed to 65% guncotton, 30% nitroglycerin (keeping 5% petroleum jelly), and 0.8% acetone shortly after the end of the [[Second Boer War]]. This was known as ''Cordite MD'' (modified).<ref>Britannica, The Editors of Encyclopaedia. "cordite".

Cordite MD cartridges typically weighed approximately 15% more than the cordite Mk I cartridges they replaced, to achieve the same muzzle velocity, due to the inherently less powerful nature of Cordite MD.<ref>Example : BL 6-inch Mk VII gun : 20 lb cordite Mk I, 23 lb cordite MD.
