Like I said... Library, Jane's "All the World's Small Arms". The 1986-87 volume [or maybe 88-89, too lazy to hit my bookshelf] has multiple views of the Hk G-11 caseless, much better detail than I've seen in net photos. [Actaully not the most powerfull in it's class - the 4.7mm caseless round it uses is a bit less punch than the 5.56mm, but it's more compact and allows a lot more rounds for the same weight and volume]

"I am a good person now and it feels... well, pretty much the same as I felt before (except that the headaches have gone away now that I'm not wearing control top pantyhose on my head anymore)"
