MKI rifle and MG stowage

Bruce, that diagram is captioned wrong. The diagram is of the "Generator, Smoke", not the "Cartridge, Small Arms, Rifle Grenade". The cartridge for launching Rifle Grenades is a .303 case not unlike a blank, however the blank is filled with Cordite and crimped, while the Rifle Grenade Cartridge is filled with Nitrocelluose and plugged with cardboard and shellac. Nitrocelluose burns hotter and with more pressure than Cordite, the heat put to better use in ignitng the smoke compound.
