I know this info is around somewhere, I just can't lay my hands on it!
What explosive filler(s) were used in the "pineapple" grenade?
I THINK the original filler was EC Blank Fire (or just plain Blank) powder, then either poured or flaked TNT (the yellow body grenades?). Not sure if there was a change from poured TNT to flaked TNT or vice versa or not at all (that is, poured TNT was never used).
Also, and this goes to the EFFECT of the filler: again SOMEWHERE I read that EC powder gave insufficient fragmentation (or was it too much fragmentation?) and that the TNT filler may have caused over-fragmentation.
Can anyone clear this up for me?
