Barnes used to make a bronze bullet. I've got three boxes of them—165 grain .308 flat base solids—that I got when a dealer passed away and his stock was sold off. They appear to me to perhaps have been scintered. Frangible bullets are made by scintering and not fusing very thoroughly. But there are plenty of more completely fused scintered parts made that are machine parts, like gears. It's not as strong as investment cast parts, but for fast and fairly precise shape production, it's not a bad method.

Note that cartridge brass has a density of 8.53, so, if you make the bullet the same volume as a lead bullet, the ballistic coefficient will drop in proportion to the difference in density. In comparison to pure lead, it would be about 25% lower, owing to the loss in sectional density.
