Real bullets, I believe.
A gen-u-wine real “hold muh drug-laced Billy Beer and watch this” moment. Even the redneck skeet shooting (in which the participants take turns playing the skeet with the aid of some kind of Wile E. Coyote trebuchet contraption) is carried out with paintball. I could understand why no sane chamber of commerce would want to have any part in this “re-enactment.”
