US Army Considers Adopting an Interim Battle Rifle in 7.62NATO: eventually adopt 6.5

[montana]

For a close approximation:

copper @ $2.50 / lb
lead @ $1.00 / lb
M855A1 slug @ 30 gr

Price difference per bullet:

Do you have the actual cost per bullet? It looks like an expensive bullet to make but I could be wrong. I have never seen any actual costs for comparison. If memory serves me correctly, we don't even have any lead mines open in the US anymore and must depend upon imports.
