Could it be a Barnes solid?

I have one 44mag cartridge that is loaded with what appears to be a solid, flat point, BRONZE, bullet. It's a reload [Starline Brass] so I don't have any leads on who manufactured the bullet. I'd like to experiment with a similar bullet in my 454.

Can anyone give me a lead on solid bronze pistol bullets? [or whatever material these bullets are really made of]

Recoil, post your question on the cartridge collectors forum. Those guys might be able to help you.
