BT-Tracer?

It is my understanding that BT-bullets have less drag than "orthodox" bullets, and thereby more range and retained energy.

I also know that tracers normally have a higher point of impact than other bullets, because of the "tracer effect", but not necessarily more retained energy, due to a relatively great loss of mass.

If a BT-bullet with a relatively small amount of tracer material (to avoid a great loss of mass) was constructed, it could be able to increase the amount of retained energy at longer ranges compared to classic BT-bullets...

Does anybody know if bullets of similar construction exists?

Do a search on base-bleed. The grognards here had a in depth discussion about it.

Ok, so it has been discussed...

But: Do base-bleed BT-bullets for smallarms actually exist?

And if they do, how well did they work?

I don't know, all that was discussed but I didn't follow it closely... Just do a search here and you'll find more than you ever wanted to know :)
