[QUOTE="Lee Owens, post: 21458, member: 73"] "Anyone know what material is used to make the sabots for the Abrams gun? " Yes. Depleted Uranium for the Combat rounds. Gunnery rounds are made of aluminum. The Army tried a Sabot rifle in the early 1970s. It got 10foot groups at 600 yards. There's a tremendous amount of information that goes into the M1A1's ballistic computer to help it achieve 3,000meter+ hits. Things like barometric pressure, air temp, wind speed at the tank, ammo temp, ammo lot#, cant angle, even a sensor to measure barrel droop and a computer that compensates for it.....etc. There's also the power to weight ratio (powder/projectile weight). I don't know exactly what the projectile weighs, but it's a 25mm dia. dart pushed by 36 pounds of propellant [img]images/icons/shocked.gif[/img] I think it would be tough to make a tiny dart that could be pushed far enough by the cartridges we use. Maybe a .50BMG case could do it. Having said all that, Steyr is working on a 15.2mm Sabot Launcher. It's intended as a squad-operated anti-materiel weapon. The projectile is separate from the powder charge. The powder looks like a giant plastic shotgun shell. [/QUOTE]
