This is what I'm talking about. No prone shooters allowed.
This match is the F-Class LR State Championships. There would not be enough room to also have prone classes so this is a class limited event....much like F-class National Championships. HP prone 'sling' disciplines also have their exclusive Nationals and such and don't have room for F-class. I think these matches are not what the OP is referring to in spirit. Monthly matches are what I referred to in my previous post. Perhaps Yvonne will get a Palma/service rifle Prone LR Champ match going
