Where can I find the rules for the 750 different ammunitions available to characters. APDS, Exploding, gel, glazer, etc, etc.?

I assume it isn't a simple answer like SR3 p. 199. They have to have spread all the different ammos all over 3 or 4 books, right?

SR3 and CC cover more or less everything between them.

There are a few unusual mortar/howitzer rounds and so on in SOTA2063, as well as bigger weapons in Rigger 3 of course. But the above two are pretty much all you need.

Thanks.
