Our club does not allow and buckshot or shot loads on the rifle & pistol range. (Skeet,Trap & SC is 7.5, 8, 9 shot. nothing larger.)

People just cannot help themselves from splintering the target stand uprights in half and otherwise shooting the stands to toothpicks on the rifle& pistol ranges.
The cables for the crank out targets on the pistol side have become targets as well as the target carriers. This may just be due to the pattern and not as much intentional. But the damage is there and someone has to repair it.

There is not an endless supply of target stands. Someone makes those up on volunteer 'work days' as well as having to continuously repair the cable and carrier systems on the pistol range.
I highly doubt the run 'n gun buckshot ninja jockys show up in that small group every 6 weeks or so to help.
It gets frustrating after a while..
