If posting actual proof and documents is " crashing out " then i have 0 hopes for you zoomers / alphas generation of brain rot mass psychotics walking flesh bags to continue research and development.
I actually got out of my way to find information on tanks and ammo, even after the corporations that made them are no longer in business. Gaijin can’t even get the ammo in this game correct, for either the standard military versions or the export variants.

Primex Technologies M829A2 APFSDS-T
After finding out that the main anti-armor ammunition of American M1A1 Abrams tanks, M829A1 “Silver Bullet” could not overcome the Soviet dynamic protection Kontakt-5, a program was quickly launched to develop a new sub-caliber ammunition to eliminate this problem. Thanks to the disintegration of the USSR in the early 1990s, the West had the opportunity to acquire several pieces of former Soviet equipment, including tanks equipped with Kontakt-5.
The analysis came up with several solutions very quickly. In the case of new ammunition, it was a combination of two basic methods, the first was to add to the tip of the projectile the so-called “Spike” covered under a ballistic cap. This spike has a cylindrical shape about 50mm long and 13mm in diameter, and its purpose is to simulate a small-caliber projectile and gradually widen a penetration hole without detonating explosive elements in reactive armor. The second was to coat the penetrator core in a high-strength steel alloy. Projectiles coated in this way have a low probability of shattering when hit by an ERA board, although they can change their direction and reduce their penetrating force, but they will not break.
M829A2 was manufactured by the American company Primex Technologies (now General Dynamics Ordnance and Tactical Systems (GD-OTS)). It was introduced into service in 1992, small-scale production began in 1993, by the year 2000, more than 150,000 pieces were produced, the price of one piece is $ 4,000 (data from 2000).
The M829A2 achieves much more performance than its predecessor, the M829A1, thanks to several improvements. Thanks to the new production process of the piercing core made of super DU, embedded in the steel casing, the structural quality of the entire projectile has significantly improved. The penetrator is 698mm (670) long, with a diameter of 22mm, and the DU core weighs almost 5kg. The JA-2 powder charge is ignited with an M129 electric match, a special production process made it possible to divide the rod powder charge into small parts, which allows it to maintain the ballistic properties of the granulate. The M829A2 was the first in the world to use a composite detachable guide sheath (SABOT) for an APFSDS projectile of this size. The three-part guide sheath is made of a graphite composite reinforced with carbon-epoxy fibers, which reduces the parasitic weight of the projectile by 30% and thus allows the use of a longer penetrator. The synthetic rubber seal at the end of the guide assembly prevents hot gases from escaping from the burning dust charge. The combination of these features managed to increase the muzzle velocity of the M829A2 by 100 m/s compared to the M829A1, to 1,680 m/s (5,500 ft/s), while reducing the gas pressure in the charge chamber.
Assumed penetration M829A2 in mm RHAe:
At the mouth [1670m/s] = 790mm ± 120mm at 0 ° & 410mm ± 60mm at 60 °
1000m [1610m/s] = 750mm ± 110mm at 0 ° & 390mm ± 60mm at 60 °
2000m [1551m/s] = 700mm ± 100mm at 0 ° & 360mm ± 50mm at 60 °
3000m [1491m/s] = 650mm ± 100mm at 0 ° & 330mm ± 50mm at 60 °
4000m [1432m/s] = 590mm ± 90mm at 0 ° & 307mm ± 40mm at 60 °
Although the M829A2 was surpassed by the new M829A3 in 2003, it was still stored in large quantities. In mid-2014, General Dynamics received $ 12,000,000 from the US military to demilitarize and dispose of 78,000 depleted uranium tank ammunition, including M829A1 and M829A2.

The 120mm KEW-A2 from General Dynamics Ordnance and Tactical Systems is a commercial version of the Army M829A2 intended for export. It is designed for 120mm cannons with a smooth bore barrel, the only difference compared to the military version is the use of tungsten penetrator instead of DU. KEW-A2 was certified for export by the US government in September 2003. GD-OTS also offers a complete logistics package for ammunition.
