Interior shots start at 1:32, eventually showing what is ejected after firing due to combustible casing. Didn't even know this existed. No empty casing to take the time to stow. Quite handy. Had to look it up:
M829
https://en.wikipedia.org/wiki/M829
The M829 is an American armor-piercing, fin-stabilized, discarding sabot (APFSDS) tank round. Modeling was designed at the Ballistic Research Laboratory (BRL) at Aberdeen Proving Ground (APG)[1], which was incorporated into the Army Research Laboratory (ARL) in 1992. The round is specifically modeled for the 120mm M256 main gun on the Abrams M1A1 and M1A2 main battle tanks. The penetrator is carried by a sabot during its acceleration in the gun barrel.
The M829 has a ballistic nose and five tail fins made of aluminum. It is carried in the gun tube by a four-piece aluminum sabot, which separates into four "petals" soon after the round leaves the gun tube. The propulsion system uses an obturating case base with a semi-combustible cartridge wall. It has a total weight of 41.1 lb (18.6 kg) and utilizes a 627 mm (24.7 in) DU penetrator with a 27 mm (1.1 in) rod diameter,[2] which will reach a muzzle velocity of 1,670 meters per second (5,500 ft/s) using of 8.1 kg (18 lb) of JA-2 propellant. Maximum effective range is 3,000 m (3,300 yd). According to Jane's, the M829 is capable of penetrating 540 mm (21 in) of RHA steel armor at up to a 2,000 m (2,200 yd) range.[3] The original M829 is no longer in production and has been succeeded by the M829A1, M829A2, and M829A3. The corresponding training round is the M865 costing $1,121.[2]
