Tungsten bullets, which are higher density than lead and have a longer effective range, are under development and the expected cost is about $1 each.

As opposed to the roughly $0.25 per round they pay now.

I think the military probably pays about 15 cents for each cartridge of 5.56mm.

55gr and 62gr military ammo is considerably less than .25 a piece. I buy about 5000rnds a year, and I pay less than .20 a round for Israeli-produced 55gr Winchester.
