AR-15s
I haven't been to a range where that would be safe, but in the right places that would be hilarious.
I love slug shooting. It's like mini artillery. Combined with steel targets at 100-200 yards it makes for fun slow-shooting with friends. Really helps with the concept of holdovers and windage with newbies too.
They redid my local range a few years ago
Back in the day, it was a big bowl, with 4 concrete shooting benches each about 20 degrees off of the next one
You could shoot whatever, ad long as you picked up after yourself
Which of course no one did
Well, now it has 5 rifle benches and 2 pistol benches
All side by side and facing the same way
I think the lanes are 200 yards, 100 yards and 30 for the pistol lanes
Now they have posts to hang targets from, you got to sign in, there's there's ranks officer, no provisions for chucking pigeons
I'm sure it still serves its purpose when you want to sight it, but they sure squeezed all the fun out of it
