I just did some simple math to get an educated guesstimate.
32 MJ. Mach 7. Speed of sound at sea level is 340 m/s. KE = 1/2 MV^2
That gives a projectile weight of 11.3 kg. I assumed a light weight sabot of 1-2 kg, leaving a ~10 kg projectile. From the color and the reflectance the sabot looked to be aluminum. Also, I remember in one interview, Admiral Klunder said something about a 10 kg projectile, so it seemed to make sense.
Maybe it was this interview:
