Anyone familiar with "Devil Dog" bombs?

I have a small bomb that I got when I was a kid at an army surplus store. They were labeled "Devil Dog" bombs. It is the size of a .50 BMG bullet but tapered instead of flat base. It has fins on the back end.
...supposedly....these were dropped in quantity with the hope that they would come from great altitude and act as bullets when they hit.

Now someone told me they were ...shot.... from a gun of some sort.

Anyone familiar with these rascals?

They were droped from airplanes during WWII. At least that's what I always heard. I also heard them being called "lazy-dog missiles". This came from a WWII AAC pilot.

Another Armament Laboratory program was coded LAZY DOG, which involved Delco Products Corporation, F&F Mold and Die Works, Inc., Haines Designed Products, and Master Vibrator Company of Dayton. The project objective was to design and test free-fall missiles and their dispensing units for use in bombers and fighters. LAZY DOG anti-personnel missiles were designed to spray enemy troops with small projectiles with three times the force of standard air-burst bombs. The Armament Laboratory in conjunction with the Flight Test Laboratory conducted wind tunnel tests of a number of bomb shapes, which design studies indicated to be the most efficient for stowage and release from high performance aircraft.

LAZY DOG projectiles of various shapes and sizes were tested at Air Proving Ground, Eglin AFB, Florida, in late 1951 and early 1952. An F-84, flying at 400 knots and 75 feet above the ground, served as the test bed while a jeep and a B-24 were the targets. The result was eight hits per square yard. Tests revealed Shapes 2 and 5 to be the most effective. Shape 5, an improved basic LAZY DOG slug, had the force of a .50 caliber bullet and could penetrate 24 inches of packed sand. Shape 2 could penetrate 12 inches of sand, as opposed to the six-inch penetration of a .45 caliber slug fired point blank.

The Shape 2 projectile was sent to FEAF for combat use by mid-1952. FEAF immediately ordered 16,000 of the 500-pound bombs. Lieutenant Colonel Haile with the Armament Laboratory spent 90 days in Japan to set up local manufacture of the bombs and to train crewmembers in their use. Project LAZY DOG continued throughout 1952 to determine the optimum characteristics for stable dispersion containers and the feasibility of substituting a LAZY DOG warhead for the explosive nose of the Matador. The LAZY DOG program was still ongoing in the late 1950s.35

Master Vibrator Company of Dayton.

I'm wondering if that had anything to do with the shape of the projectiles.

Is this the guy?

My father when he was working out at China Lake CA said he saw tests of these little guys. He said that they were brutal, and they went through everything including trucks and cement walls.

At 8 hits per square yard, there would be scant little left alive.

That pic is the one. I think I got mine as a kid at a surplus store when surplus stores sold surplus.

Think they were 50 cents.

Those stats are hard to believe. Released at 400 knots at 75 feet doesn't SEEM to be enough to make em as effective as a .50 BMG.

Dunno. 24 inches of sand. Brick walls.

I assume they would be dropped by a bomber doing at least a few hundred miles an hour. That speed would get added to the speed from the fall.

I've had one of those in a "box o junk" for years. I never knew what it's purpose was until today. Thanks guys!
