Sure, burn pits and other crap will help.

But this kind of ammo, kids will find and hang on to. They bring it home, add it to their collection of other cool shit they've scavenged...and then their brothers and sisters are born with malformed limbs, mishaped heads, etc.

There have been a lot of stories written about it over the years. The one I read was specifically about Iraq I believe, but it was a while ago.
