I mean, I feel for the dude, it does suck to get washed while you’re trying to fine tune your zero, but I’d have just changed lanes if I were him and it was an option. You’re allowed to shoot, just as much as anyone else there.
People that try to essentially call a cease fire on an always live range, crack me up. “Sure, I’ll just stand here while you print a five shot group, taking a full minute between shots to write in your notebook. It’s not like I paid for range time or anything.”
