Gun clubs here are very active. 2 hour wait for a lane last Saturday morning at my local range, unless you were a member, with a reservation.
I had a reservation. We tried out my friend's new Daniel Defense pistol, and she tried out my AR and my Daniel Defense .300 BLK.
Sent quite a few down range, in various calibers, but we weren't the only ones. Every lane was full. Every lane was sending them.
There were dozens of people in line to buy firearms, dozens and dozens more waiting for their turn on the range, with a buzzer in their hand.
Different experience than yours. Perhaps the PA folks with whom you're associating are hoarders, I can't say, but a lot of folks down here are shooters.
In casual conversation with many shooters, they bought their ammo previously, at reasonable prices. Many others bought their ammo that day, at crazy prices, precisely because they wanted to shoot. I see an interesting mix of experienced shooters and relatively new shooters.
It may also be that the folks at your range failed to stock up when ammo was cheap, have no ammo, and don’t want to buy it at the current, inflated prices. So, with no ammo on hand, they don’t shoot.
You presume that your anecdotal observation, at your one club/range, is universally true. I assure you that it’s not. In the shooting community here, not that far away, across multiple ranges and stores, it is very different. People are buying ammo, and shooting it.
