Yes, I do. It refers to a round that has a subcaliber projectile contained within a (usually discarding) container referred to as a sabot, after the french wooden shoe. It's designed to provide a higher velocity than normal by using a standard charge with a lighter, small projectile. It's most commonly found in the Armor Piercing Fin Stabilized Discarding Sabot (APFSDS) loads used by tanks for anti-armor work.
The M230 chaingun on an AH-64 doesn't use sabot rounds. In fact, I'm not aware of any aircraft that does due to the danger to the aircraft posed by the discarding sabot and by the fact that the potential accuracy/safety issues posed outweighs their penetration ability, especially given that aircraft usually attack the thinner top armor of vehicles, where the sabot round is not necessary. Further, the M230 is for engaging relatively soft targets such as APCs and support vehicles. Those targets it can't deal with are best left to the Hellfires.
