I've been getting stuff ready for my first 3 gun shoot and Ive got all the basic things I think I'll need (guns,mags,pouches, and ammo). My only question is, what are some things I need to bring that a first timer wouldn't think of? I'm talking about things like eye and ear pro, soft cases, hard cases? I've been told ill need chamber flags. These are the type of things I'm wondering about. Is there a list anywhere that would tell me the things I might overlook?
