" ... long ago I had a box of brass cased .45acp ammo from Brazil that looked like it was military. It had a green tip on the bullet but it was not tracer. I think it was intended for subgun use and a .45acp pistol would not set off the primers. Any ideas what this ammo was?"
Found this on Gunbroker:
"This tracer is a traditional Soviet green tip tracer and will start to trace bright green right out of the barrel and will continue to trace for 400 yards. It has a very bright green trace and can be seen day or night. This tracer is made to true Soviet military tracer specifications."
The above said, look at the base of your bullet. If it's lead, it's not a tracer. A tracer would have a hollow base filled with trace element. If it looks like there's a substance on the base, or it has a plug, it's likely a tracer.
I searched elsewhere, in cartridge collector sites, but couldn't find anything definitive. Hope this helps.
