Doesn't say exactly what rounds but air to air was .308, .50, and some 20mm.
I'd guess they were training with 30-06 and .50 BMG.

Interesting. I recall reading about the P39 Aerocobra aircraft that were used as target planes for the frangible munitions. Apparently they had lights that flashed on and off when they were hit. I'm not sure I'd want to be a pilot in one of those although it was probably fun to shoot at them.
