Then why don’t you look it up?

Are you going to tell me some of the hippies was carrying a 30-06 so they match the ballistics to the National Guard?

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.
