The lead-free bullet "green" was a different compostion, not tungsten. You can't melt Tungsten and put it in a case. You'd have to use a sintered (powdered) tungsten and form/press it into the jacket. 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.

US combat ammunition is still a combination of lead with a steel rod (62gr M855).

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.
