The World's Largest Shotgun Shell?
A guest post from Shooting Editor and Shotguns Columnist Phil Bourjaily
This video shows what must be the world’s largest shotgun shell: the 120mm canister round designed for the cannon of an M1 Abrams tank. The 50 pound shell contains 1150 .40 caliber tungsten pellets launched at 4500 fps, with an effective range of 500 yards.
What’s fascinating to me is that you can see clearly that the shot charge of the canister round behaves exactly like a load of shotgun pellets. As the round leaves the muzzle, the pellets at the front of the pattern encounter air resistance and begin to peel off and fall behind the main charge, opening the pattern and forming a shot string. The pellets to the rear of the shot column draft behind the leaders, retaining velocity and moving to the front. The canister flies with the pattern for quite a ways (our light plastic shotcups have petals that open open and slow the cup quickly). Eventually, though, the poor aerodymic shape of the canister causes it to slow down, and you can see the trailing pellets catching up and passing it in flight.
The last shot shows how much the pattern opens up at long range as the shell decapitates every one of a row of targets that must be 30 yards across. Given the price of tungsten, I can only imagine how much the three shells fired in this video must have cost. Best not to think about it; just click “play” and enjoy the sight of your tax dollars flying downrange.

Just the thing for clearing snipers and terrorists out of dense patches of woods and cover. It would also work well in urban areas, or against a huge AK wielding mob coming at you in a human wave suicide charge (Mogadishu?).
Or, you could just use it to jump shoot flocks of elephants.

If that's real I'm more impressed with the camera that could track the load than I am with the shell.

Speaking of the price of Tungsten. Has any checked the price of reloading components lately? It is not pretty.
Most of the sporting goods stores in my area don't have much in the way of inventory either. One store owner told me that the price of raw materials is going up so rapidly that the manufacturers are reluctant to take any orders that cannot ship almost immediately.
I am thinking about buying a new rifle in 338 Federal, but I am going to have to get a second job to buy components.

It's a shame that we have to use non-toxic shot on terrorists also... But plain old lead ain't cheap anymore either!
In my neck of the woods lead shot is $59 per 25 pound bag at Bass Pro. If I had known this 4 years ago I would ahve bought all I could haul at $16.50.
I think the best investment in America right now is lead shot and rifle bullets! My wife is a buyer for a local hardware company that sells ammo. Last year she booked promo Dove Loads at 2.99 per box. This year they were $5.09... cost... Don't even ask about the good stuff!

Amazing photography that shows how a pattern actually blooms and develops in a shot string! The 120mm cannon is a smooth bore with what amounts to a cylinder choke. I'll bet Brister and Burrard would have loved to have seen this! It basically confirms all their predictions.

As a current Marine Corps tanker in Iraq I hate to say that our main gun privilages are highly restricted. My tanks carry 2-3 canister rounds, but the collateral damage is so significant I can't imagine ever getting cleared to fire one. The coxial machine gun is our bread and butter now, puts quite a bit of steel on target with exceptional accuracy.
As for the old 105mm beehive round, it actual outranged the current 120mm canister round because you could set it to burst at a certain distance. That way you could launch it at troop targets over a kilometer away, and it would burst just short of the target for max effect. Plus it contained flachette darts and not ball bearings.

The legend goes, that General Bell was visiting some tankers in Iraq, and a young soldier was asked if he needed anything, and the good soldier, being a good soldier said, "General, it would be nice to have some of those canister rounds". and the General said, "You don't have them already?" So they got them very shortly afterwards.
At least that is how the Military Urban legend goes!!

I would like to see an over/under version fired simultaneously, now that would be tax dollars at work. It also would be a whole lot more interesting than watching an avalanche on Mars for even more money. I also feel that Devil_Dog and his crew should have a case of these cannisters if they want them. God bless and be with you Devil_Dog.

Amazing how we now send our children out to fight and tie their hands behind their backs... my sympathies Devil_Dog and thank you for protecting my family and myself. Imagine the collateral damage of one of these puppies! I guess they're phasing out the beehive because it was too effective.
A few of these along the border would significantly reduce illegal entry. Just a thought, as it would probably only have to be used a couple of times like Nagasaki and Hiroshima.
As for usefulness as a hunting tool I can see ten or twelve lined up pushing the deer through the woods and am surprised that the insurance companies have not yet purchased vast quantities. Deer/vehicle collisions down by 25% the first year is my guarantee and am willing and able to oversee the operation as killing without hesitation is almost an art form in my world.

The 105mm howitzer beehive rounds were a real hit in Vietnam. When the VC tried to overrun an artillery battery, they'd often get a nasty surprise in the form of those beehive rounds--some 5,000 flechettes in each one. Viet Cong were literally "nailed" to trees by these flechettes. I suspect that tungsten balls are used in the M1 tank canister round for unarmored vehicles. Oh--looks like we have the same problem as in Vietnam--getting "clearance" to use certain weapons. By the time you get "clearance," the enemy is gone.

For perspective, a 12 gauge barrel fits lead balls at 12 to the pound. The Abrams M1 120mm is about 0.044 ga. A 120mm lead ball is about 22lbs 10oz. Devil Dog has earned the keys to the ammo locker.

Nice link Scott and WOW did the first part ring true... my son went to grade school one time with a reversible jacket we had just bought him and the pockets on the inside were full of .22's. Automatic "no tolerance" year's suspension. Luckily his teacher went to bat for him because he was at the top of his class and had never caused any trouble. Still we had to go before the school board and the principal and teacher were seated beside me so three days was all he got and his teacher "mistakenly" wrote it up as an excused absence.

When I was in school in WV, which was in the late 1980's, the conservation officer for each region came around to each junior high school and taught Hunter's Education during study hall. There were four days of instruction and then a one hundred question exam on Friday.
While I can't speak to the issues that are leading to a decrease in the number of hunters in other parts of the country, here in the mid-Atlantic region is undoubtedly an issue of land access.
The number of hunters in WV started to decline drastically when Westvaco, GP, and Pochontas Land (aka Norfolk Southern) started to lock up there lands in exclusive leases. Prior to this, it was possible for anyone to buy an inexpensive permit to hunt on any land that was not being used for timbering and the like.

I suspect that a small light mirror was rotated to track the round down range.
The moving mirror can be very light and the turn rate varied to track the flight of the round downrange.
Even if the mirror massed only a few grams, to go from stationery on the tank to tracking the round must have required a huge torque, with quick and accurate control.

The US used similar 155MM rounds in Vietnam. I believe they are still in the inventory (new stock).
I wouldn't be suprised if the old 205MM cannons had they as well.
For point blank work, an old trick was to use a bucket of nails and discarded powder charges. My reciepe adds ketchup.

Not the largest shotgun, I'm afraid. :)
The Brits were putting carronades on their warships already in the 18th century, and the 68-pound carronade has a muzzle diameter of some 205mm. Roundshot, followed by a cask containing 500 musket balls, and the damage is simply ludicrous. So's the range, of course...
At Trafalgar, Nelson's flagship HMS Victory cleared the gundeck of the French ship of the line Bucentaure with a single salvo, including one of these beauties, firing a raking shot through the stern windows, and causing almost 300 casualties with a single volley...
IIRC the Beehive round used in Vietnam was only available in 105mm version, btw.

Heck, when I was in middle school in Houston, which was in the late '70's, we had a gun club with a teacher sponsor and every Thursday after school, we'd go to the gun range and try different guns. I think we started with .22 rifles, pistols, shot skeet for my first time, either a .357 or .44 mag pistol, high-powered rifles and black powder is what I remember. Can you imagine that NOW??!!
A lot of change in 30 years. And not for the better, I think.

A bunch of warography. Love how all you people are getting "excited" all over your computer screens about this.
I've been the guy yelling Fire in an Abrams and seeing the effects. Ever see what a 120mm heat round does to the inside of a house? Yes you fire at a house with a bunch of terrorists, but WHAT HAPPENS WHEN YOU THE HOUSE SHARES A COMMON WALL WITH ANOTHER HOUSE WHERE MOM, DAD, GRANDMA, ADN 6 KIDS ARE HIDING???!!!!
Now, ask me why after 10 years in the Army, 2 tours, I got out, ask me why I don't sleep well at night!!! Every wonder why so many of us have PTSD?
