I just spent about an hour trying to "look it up". The answer is there was never any ballistic testing done. Absent that proof, the caliber of the bullets that hit the students is still unknown. The .38 revolver in the possession of Terry Norman had been fired. There were 30-06 bullets found in a statue and nearby tree. Presumably, 67 expended 30-06 casings were recovered. Revolvers don't eject brass, so no accounting is available for where Norman's rounds struck. It is unlikely he would have attempted a reload, so nominally 6 rds could have been discharged.

Would ballistic tests be necessary when the coroner pulled .308 bullets out of the dead students? Wouldn’t a coroner understand the difference between a lead bullet measuring .357 and a jacketed bullet measuring .308?
