My feeling is you gotta cut the pistol guys some slack. A lot of them aren't even shooting at the knock downs, much less hitting them.
Last time I was there guy with .50 Desert Eagle wasn't hitting anything but his forehead from the recoil.

If they're not shooting at the knockdowns I don't feel their obligated to reset them. If they do, then hey, their Momma and their Pops raised them right.
They should help repaint the gongs though
When I went, seemed like the .22 shooters were setting up, and that was good. If anything just tap the the rimfire shooter next to you and give them " hey, let's go "
I'm with KK in that some of them don't even know their allowed out there.
Seems like rimfire rifle guys knock down the vast majority of the knockdowns when I'm there. ( I'm a rimfire rifle shooter and my kids love resetting targets )
P.S. They allow .17 HMR which easily takes out the long distance knockdowns.
As for Brass, your own bucket with a sign sounds classic. " PLEASE PUT MY BRASS HERE "
Of course, he can have all my rimfire brass he wants.
