Hot Rounds

thermobaric bullet or “natural” dieseling?

This is the Army’s new M80A1 EPR 7.62 bullet. It is made just like the M855A1 5.56 bullet: a copper base core behind a hardened steel penetrator front core with a gilding metal jacket. Hey, it’s lead free and thus “green”! Weighs in at about 130gr I think. It is not fired at any kind of extreme velocity. The bullet has been designed to fragment, usually breaking apart at the cannelure line the way Ball 5.56 ammo did back in the early 60s.

I’ve seen a lot of ballistics test gelatin block videos. I can’t recall ever seeing one that created an internal explosion that sat there huffing smoke rings before.

The flash you are seeing is real. Apparently gelatin block has some kind of flammable vapors in it (news to me I thought it was just Knox and water); when the bullet passes through it creates an enormous primary temporary wound channel that sucks lots of air into the entrance hole where it can mix with those vapors. When the block collapses - again at very high speed - it’s Chem 101 and the old PV=NRT ideal gas law - air temperature and pressure soars as the volume instantly diminishes to almost nothing, and this self ignites like a diesel engine. FOOM. And creates a One Two punch of a second temporary wound channel. And then the block sits there blowing smoke rings.

Enemies beware: not only does this one kill you dead, it blows you to shreds - twice - and sets you on fire. Oh, and it also shoots right through Level III armor, even at long distances. Nowhere to hide.

Horry Clap.

Not that very many people ever read this far down, but this blog was the creation of Allan Kelly and his friend Vilmar. Vilmar moved on to his own blog some time ago, and Allan ran this place alone until his sudden and unexpected death partway through 2006. We all miss him. A lot. Even though he is gone this site will always still be more than a little bit his. We who are left to carry on the BMEWS tradition owe him a great debt of gratitude, and we hope to be able to pay that back by following his last advice to us all:
  1. Keep a firm grasp of Right and Wrong
  2. Stay involved with government on every level and don't let those bastards get away with a thing
  3. Use every legal means to defend yourself in the event of real internal trouble, and, most importantly:
  4. Keep talking to each other, whether here or elsewhere
It's been a long strange trip without you Skipper, but thanks for pointing us in the right direction and giving us a swift kick in the behind to get us going. Keep lookin' down on us, will ya? Thanks.

Oh, and here's some kind of visitor flag counter thingy. Hey, all the cool blogs have one, so I should too. The Visitors Online thingy up at the top doesn't count anything, but it looks neat. It had better, since I paid actual money for it.
