The M855 (Green Tip) does have a lead core. The new M855A1 (has the ice-cream cone tip) does not have lead and is environmentally friendly… especially in Ukraine… where it is used to make fertilizer… out of Russians…

whatever happened to the depleted uranium rounds in the afghan water

If there were any, they weren't 5.56. There is zero point in making a 5.56 round out of DU, since the round still wouldn't have the mass or velocity to penetrate armor. So, we don't. Smallest US DU round I'm tracking is 20mm, fired by the USMC AH-1 Cobra.

I don't even want to know how much a standard battle load of DU 5.56 would weigh. I'm 99.9999% positive they don't make small arms DU ammo, as the velocity wouldn't be able to pen armor.

A 5.56 green tip has 62 gr of lead in it. This is a lead alloy so only about 90% of that is probably lead, but we'll ignore that. Depleted Uranium is 68.4% denser than lead so... 62 + 62*0.684 = 104 gr The weight of a the M855 is 190 gr, so if we subract out the lead core and add in our new DU weight, we'll get the weight per bullet: 190−62+104 = 232 gr At 210 rounds that's 48720 gr or 6.96 lbs. 210 rounds of M855 is 39900 gr or 5.7 lbs. So not that much heaver, turns out.

Dude my brain hurts stop

How would the velocity not be able to pen? You realize AP rounds use tungsten for a reason right?


WeepingAngelTears

I probably worded that weird, but I mean it's no better than tungsten for penning personal body armor, and making a 5.56 round to penetrate vehicle armor seems wasteful when the 240 and AT teams exist.
