Base - Mk 8 Mod 4 (B.I.F.) |
This ammunition is used in coast guard guns. Their bursting charge is black powder and TNT, or black powder alone. This should be kept in mind when unscrewing the fuze, as some of the powder may have fallen down into the threads and the friction would cause detonation. |
The Primer Mk 10 Mod 8 may be used for saluting charges only. |
Base Fuze Mk 2 Mod 9 and Mk 8 Mod 5, without tracers, may be used, but the Mk 8 Mod 4 is the preferred assembly. |
This round may be issued B.L. & P. for target-practice. |
