    Depleted Uranium long-rod penetrator from an M829A1 APFSDS-T (Armor-Piercing, Fin-Stabilized, Discarding-Sabot,-Tracer). The round has just left the muzzle a 120mm Main Gun as used on the M1A1 and M1A2 Abrams. It would be going @ 5400fps, as the air resistance has broken the driving bands and is peeling away the shoes(sabots). The training rounds actually have a perforated cone at the rear that acts like a drougue chute to slow them down so that they don’t skip on the atmosphere and exceed the impact area of our tank ranges. As an old tanker, I’ve fired a whole lot of these. No discernable ballistic arc out beyond 2400 meters. I can load a round in just about 2 seconds and shoot groups at 1200m that match Firefly’s at 50m. Considering the 1500-2000 intervening years, this is a very good comparison.
