I guess he was being lazy could have replaced with one from rear also I believe they should have been mounted in a more stationary position .It is flawed. Cast iron is brittle. Once one shot goes through any given pan, any nearby shot close to the first hole is not valid since the integrity is compromised.
He should have used a new pan for each shot.
Guy should play the lotterythere testing is flawed .. there are all new pans and not well seasoned .. who the heck uses a un-seasoned cast iron pan .. .. its a wounder every round didn't get stuck to the first pan .. now a well seasoned pan .. that could get interesting ..
