I don't think the gear has a lot to do with it, I started plinking at my local club about 18 months ago and in that time I have been lucky enough to put together 2 different setups a Steyr with quite a good scope also a S400 with a cheap BSA scope, after a disasterous comp at Blanau at the weekend using the Steyr, I am seriously thinking about selling it and just keep the 400 it is every bit as good as the Steyr, and after the weekend I think I could have hit more targets using open sights, so I don't think you need top quality gear to be good.
