Maybe the dumbest hunting/shooting interaction I've ever had was a few months back at the range while waiting for a bench to open up. Couple guys in their mid-20's are working to get a rifle bore sighted. The seemingly more experienced of the two is acting as spotter/advisor and offering questionable marksmanship advice. He strikes up conversation with me so I inquire if his friend is a first-time shooter: "Yeah he just bought his very first rifle. He doesn't know what he's doing so I'm helping him zero it before deer season"…. after a few more minutes they're ready to light off the first rounds and he starts to warn people on adjacent benches that it's gonna be loud. The shot absolutely blows all the neighboring shooters out, especially the 10 year old girl and her dad directly to the right of the muzzle brake.
Me: "What in the hell is he shooting?"
Him: "A 338 Lapua Magnum"
Me: "And you told him to buy that?!"
Him: "Well I wanted him to get a 308. But he'll be able to shoot to 1000 yds with this"
Him: * Struggling to spot shots from offhand binos so I let them borrow my spotter * "Ooooh that's not great, we need to shoot another group"
6 shots in and the shooter is begging for a break, the people up/down the line are agitated by the muzzle blasts. Spotter persuades him to shoot one more group, then decides to jump in and rips off his own group. Meanwhile the father and daughter are visibly upset and just quit shooting. Spotter asks me to survey the target. It resembles a shotgun pattern and is about 10" at 100 yds.
Him: "Well what do you think?"
Me (noticing the scope is some cheap 3-9): "Um… I don't think he's quite ready for deer, but he's definitely not taking this thing to 1000 yds"
Him: "What? That rifle will easily shoot out to 1000"
Me: "Yes, this rifle will even exceed that, but HE won't. * glancing at the 20 rd box of cartridges with a big $149.99 pricetag on it * "…and you know you can't hunt with these here, right?" (Non-lead requirements)
The shooter blurts out: "WHAT?! He told me those are a good hunting bullet. I bought five boxes!"
