I've always had an interest in doing this. I read the whole thread and need a lil more info. Three gun, pistol, riflle, shotgun? What are the requirements? My AR15 is a heavy 24" bull barrel. Can I use an AR10 instead? I have a looong semi auto 12ga, can I use a smaller, lighter 20ga pump mossy? Some more info, or a link would help me out a lot. thx guys.
Remember this isn't bench shooting or even firing a few & walking down to check target hits. This is clearing a stage, shooting quite a few rounds while moving. That said the 24" bull barrel may get a little heavy by the end of the day, maybe not, depends on you. Yes you can use an AR10, you wouldn't be the only 1 shooting .308. But you may need to think about cost of ammo, consistency after that many rounds etc, again up to you.
I'm not sure what you mean by long but most of us use 22-26" barrel S/A shotguns, with a 9+ rnd capacity. A few use pumps, but pumps are a little slower than a S/A. I've not seen any 20ga but as long as it'll knock down the steel it should work. There'll be plenty of Shotguns there that folks will be more than willing to loan out.
Don't let the lack of gear stop you. After you figure out what works best for you, you can start "gearing yourself up". Then you can payback by helping the next guys. Most of us started out with borrowed gear, especially shotguns, and are more than willing to help out fellow shooters new or old. That's the beauty of this whole community. It doesn't matter who you are or where you're from, or what your skill level is, we all just want to have fun & further the sport. I've never seen anyone not help for fear of competition. Most of us bring extra gear just in case someone forgot something.
Everyone would like to win, but unless your one of the very top guys, it's really more about competing with yourself & trying to improve. I've never seen anyone get pissed because someone beat them. But I have gotten mad at myself for not doing as good as I could because I didn't follow my game plan (or because Jesse DQ'd me

).
