M1030 Breaching Round

New Ammo Will Decrease Fragments in Close Urban Environs

Brig. Gen. James E. Rogers, commanding general of the Joint Munitions Command at Rock Island, Ill., approved the full materiel release of the M-1030 12-gauge shotgun breaching cartridge in late 2007.

“The M-1030 is an anti-material cartridge designed to be used for defeating wooden doors (deadbolts, knobs and hinges) and padlock hasps,” said R. Ned DeWitt, product manager of crew served weapons with the Armament Research, Development and Engineering Center. “The cartridge is functional with the Mossberg 500/590 and the Remington 870 shotguns. The cartridges will be tested in the XM62 Modular Accessory Shotgun System as part of the product qualification testing for the weapon.”

The round is designed to cut down on the number of fragments scattered by current breaching, normally 00 Buckshot. I guess I thought that they already had specialized breaching rounds. I sure wouldn’t want to hold the muzzle of a 12-gauge up to a locked door and pull the trigger on a load of 00 Buckshot.

Anyway, don’t miss this bit:

The M-1030 is a Soldier-enhancement program that uses commercial-off-the-shelf technology. The first requirement was approved by the U.S. Army Infantry Center in 1997.

It took 11 years for a COTS program to come up with a new shotgun round in the middle of a war. I’m glad they didn’t decide to design this thing from scratch. By the time they got it right it would have been made obsolete by wrist-mounted laser cutters.


  1. The cartridge is functional with the Mossberg 500/590…’ Good to hear…just in case I need to break into my own house. And, uh, I have my Mossberg on me.

  2. Things that make you go hmmm. Door breaching rounds The US DoD Door Breaching Round is lethal and extremely destructive. DO NOT fire directly at person(s), serious injury or death may result. Intended for use ONLY by qualified personnel properly trained in the specific use of door breaching techniques. This ammunition can cause contusions, abrasions, broken ribs, concussions, loss of eyes, superficial organ damage, serious skin lacerations, massive skull fractures, rupture of heart or kidney, fragmentation of the liver, hemorrhages, and death. http://www.cqbsupply.com/doorbreaching.html

  3. Yeah, you wouldn’t want to shoot the enemy with a lethal round. Better grab that M-16/4 and put that little .22 cal hole in them. It’s almost guaranteed not to be lethal, assuming the gun doesn’t jam before you get the chance.
