I have never been to a bigger shoot, but I hear stories about guns getting stolen ect. I was thinking that one of those coated cable lock would work to lock it the gun rack. A guy could steal part of the gun, but you would think someone would ask questions if they seem them messing with it while locked up. You could always bring it back and lock it in your car, but then it only takes a few minutes to jimmy the lock or break out a window. You guys with higher end guns; how do you secure your guns when not using at a place with a lot of people?
