The MPL postal series along with the Lancashire and Norfolk clubs can lead the way for Supported Shooting in the UK.
Supported Air Rifle Shooting (SARS) and Supported Air Pistol Shooting (SAPS) is not as easy as people who haven't ever tried it seem to think it is - in fact some that have tried it for the first time at our club have said that is is much easier to shoot freestanding as the body is a wonderful shock-absorber - and this is totally lost when the rifle or pistol is balanced on a very small tangental footprint between it and the hard surface of the 50mm steel bar.
I will send you some pictures of my cheap and easy to make bar holder's that we made and use to hold the 50mm dia steel bars. We had our bars cut to 125mm long and they just drop into the plywood holder so the bar can be turned or lifted out if or when required.
The holders can be easily mounted on top of any suitable stand. We use heavy duty speaker stands as they are rock solid, inexpensive and look good too!
Using these stands makes it easy to shoot SAR at 10 meters or at 6 yards (or any other distance), so if you do get the bell target shooting started at the traditional British 6 yard distance you could also shoot SARS at 6 yards too and maybe you could see if anyone would like to enter the MPL postal series - the first and ONLY current competition for SARS and SAPS shooting in the UK!
Good luck with your efforts to save your club.
