It’s more like 65. He was using a pistol at a distance, as confirmed from multiple sources, and the interview (to me) it sounds like he was guesstimating one hundred then decided that 65 was more like it.
No independent confirmation on distance yet, but reports indicate he was firing from the other side of a sort of ‘courtyard’ or central square in the RV Park, so some distance.
65 yards with a pistol? Wow. That is some outstanding shooting.
