The M1028 is a 120mm shotgun shell for the M1 tank. The shell holds 1100 10mm tungsten balls. They are apparently lethal up to 700m (765 yards). Here is a video of the shell being fired in slow motion. It shows the shot breaking the sound barrier and the shot pattern (H/T to Sebastian).
I tried to calculate the weight of each ball. It depends on how pure the balls are. My calculations, based on a company that makes tungsten balls that weigh 18 grams per cm3, indicate that each ball will weigh about 145 grains. That is a combined weight of 159,500 grains / 10 kilograms / 22.8 pounds!
(4/3) x pie x 0.5cm ^ 3 = 0.52 cm3
0.52 * 18 = 9.42 grams (145 grains)
Please correct me if I am wrong.
The requirements of the round were:
Defeat >50% Advancing Squad w/ 1 Shot
Defeat >50% Advancing Platoon w/ 2 Shots
200-500M (threshold)/100-700M (objective)
Muzzle Action (i.e. No Fuze)
No orientation of the projectile
Vulnerability no worse than current fielded
The M1028 cross section.
Here is a before and after shot taking during the testing of the round. I am not sure of the range.

Two dummies survived, the wall did not.
The concept of shot is not new. Grape shot or loose stones, metal and glass have been used for as long as cannons have.
B.B. has written two posts about the air guns launched at SHOT. I was going to cover the SHOT air guns, but B.B. knows a lot more about the subject than I do.
Auto-Ordnance has a new “Tactical Folding Stock Model” M1 Carbine out later this year.
Black polymer folding stock, metal handguard
The Auto-Ordnance M1 .30 Caliber carbine is produced in Kahr’s state-of-the-art manufacturing plant in Worcester, MA. The Auto-Ordnance carbines are produced using newly manufactured parts on high precision computerized machinery.
Markings include the following: Auto-Ordnance, Worcester, MA behind the rear sight; U.S. Carbine, Cal. 30 ML on the receiver in front of the bolt and the serial number is engraved on the left side of the receiver.
This new ammo from Lapua is going to be the most expensive .22 LR ammo when it is released, and apparently the most accurate.
Lapua rolled out a whole new line-up of rimfire competition ammo in three grades, X-ACT, Midus Plus, and Center-X. The ultra-premium X-ACT ammunition, which may be the most expensive rimfire ammo ever produced, is designed to out-shoot the best Eley has to offer.
The rep from Lapua at the SHOT show expected pricing to be 20-25% higher than anything else out there. He also said that the people testing the ammo (real compitition shooters) have been seeing group reduction of 30-50%. That’s impressive if true.
Hi, welcome to my blog! This blog is dedicated to all things firearms related. I hope you enjoy it.
I want this blog to appeal to a worldwide audience and so I will be focusing on firearms and shooting rather than country specific politics. There are already many great blogs defending your rights!
