Now who that day was using rifles chambered in .223?

In before the usual suspect shows up to claim that the autopsy report shows what type of weapon caused each wound.

The autopsy reports only indicate "medium" and "small" caliber.

They do not indicate the additional ballistics data to determine what weapons those bullets came from.

Both 7.62 mm and 9 mm are considered "medium" caliber.

Without bullet weight and/or other ballistics data, it is not possible to tell if the round came from an AR-15 chambered in .300 blackout or a 9mm Hi-point pistol (both "medium" caliber), for instance, nor whether the "small" caliber wounds were caused by .223 (AR-15) or .22 long rifle (.22 pistol).

“In before the usual suspect shows up to claim that the autopsy report shows what type of weapon caused each wound.”

Six of the identified bullets were medium/large in caliber. That is at least a .38.
