Don't forget the lowly Frag Grenade. Not sure that counts as a Gonne, not being an arm, merely thrown by one
Dan,
How old are you? Are you a WWII or Korean War vet?
The Mk10 fuze was the last grenade fuze to use a Black Powder bursting charge because some of the Mk2 grenades used EC powder as the filler instead of TNT flakes. The M26, M61 and M67 grenades all used or use a Mk204 or Mk213 fuze which uses lead azide, lead styphnate, and RDX as the detonator charge. The later Mk2 grenades also used the Mk204 fuze. They went back to composition B or TNT with the notched fragmentation coils and even the old Mk2s were all the TNT variety from what I understand. The current M67 bodies with their internal nubbies use Comp B and the Mk213 fuze which has no BP.
They pulled all of the Mk2s after Korea because they were truly a defensive grenade with the TNT charges and the large hunks of grenade body that would travel farther than the advertised blast radius.
I know the Soviet Vietnam era grenades all used TNT as their fillers so they wouldn't use a black powder fuse, the Chinese grenades were all copies of the Soviet designs.
I know I've never thrown or used a grenade that had BP in the composition except for an M62 or M69 practice grenades which use BP as the marking charge. I never saw those anywhere beyond the training pits at TBS.
We made fuzes, timers and bursting assemblies so I'm familiar with the Mk204 series and Mk213 series as well as the Mk205 series (BP practice) fuzes. The bigger ordnance uses a composite fuze and bursting charge so the BP works better and has the space for it you don't have in a hand thrown grenade with a body full of Comp B or TNT. They're all Comp B now.
