Possum,
You may not realize how much commercial steel targets cost.
A rack of 6 falling plates costs well over $1000. A pepper popper starts about $150 (and rifle rated pepper poppers are well above $300 IIRC). It is easy to understand why clubs are sensitive about what you shoot their steel with. The club I belong too will ban you for using any long gun on the plate rack. The thought process is that if someone sees you shooting with your lever action .22, they may decide that their lever action .308 is just fine too. Therefore, no long guns on the steel, at all.
I suspect your annual membership would pay for less than one steel target.
Any steel target with craters or holes poses a risk of bullets coming back to the shooter and other people on the firing line, or leaving the range. I hope your targets are in good shape.
atek, that's the way to do it.
