I want to shoot my first Steel Challenge (probably Griffin Ga.) and I need some equipment advise. I don't want to slow down the match by not being properly equiped. Guns - Ruger 10/22 ITAC - no iron sights - Walther P22 Questions: Magazines - How many for each gun should I have? Scope - What type of scope do most people use? Some magnification would be nice (2x?) but I don't want to spend a lot for it. Can I use a scope on both guns in compitition? I would like a scope that I could use on both the rifle and pistol. Do I need any other (except safety) equipment? Holster?
