Does anyone happen to know anything about the US experimental XM866 120MM TPFSDS round? I have only been able to find one short article that mentions it. I have learned that it was designed to be a “Long Range”, target practice round. I do not think it was ever adopted? I will post some pics of the 2 projectile variants I have. With the exception of the paint color and penetrator materials, the sabot and penetrator exactly match that of the tactical M827 APFSDS-T round. The M827 was only adopted for a very short period before the M829. My camera battery is dead but I’ll get pics soon. Any information on this round would be greatly appreciated if available. Thanks.
