A Simple Encounter, probably good for a few night's play.

From memory, "beehive" was originally a specific reference to Splintex, based on a project name or code name or something like that.
Splintex is a little different to typical cannister rounds not just because it used flechettes rather than balls but because it used a timed fuze.
It was definitely intended as a direct fire round fired from a horizontally inclined barrel but I suspect it could be possible to use it in indirect fire at short ranges.

There's a claim floating about that the Soviets developed similar artillery rounds for indirect fire with 122mm and 152mm guns but I'm still trying to find some authoritative source for that. While a number of sources mention that for example, the 152mm D-20 has a flechette round, they don't state the specific ammunition name so I haven't been able to find if it's for direct or indirect fire but I suspect its the former.
And that's probably because any Splintex type round the Soviets (and anyone else) might have developed has pretty much been superseded by better HE-Frag or sub-munitions rounds.
