I've just found that one. Unfortunately, although it's described as an 'anti-armor rifle', it's pretty much a standard 14.5mm rifle firing discarding sabot rounds.

There's also a Thud gun in T20, but that's a beanbag gun and also the Kafer assault rifle from 2300AD, but I have been unable to find anything resembling the OP's description in my collection.

From my dim recollections, I think it was called a "Crunch Gun" in the 'Traveller: New Era' setting.
