Guys, I won't be showing up in OK this year, but I can share my equipment list if you'd like.
On the subject of safety, Whenever we go into the feild for a shoot, we establish a firing point, or line, and always know where the other guys are. Even when there's only 2 of us, we announce any change in position or attitude or feild-of-fire. When the shooting heats up a guy can get excited; another reason why I like 2 or three person teams best. In a really big town I've seen as many as 10-25 shooters shooting having at it. Pick your feild of fire and positions so that, so long as the firing line discipline is observed, no-ones muzzle will cross another person. I've seen "lines" that were a series of 2 or three or 5, whatever, person groups in a line several hundreds of yards long.
Loaded weapons only at the firing points. Unload and make safe before removing the rifle from the established points, hammer down on an empty chamber is the minimum safe practice IMHO. Case them when not in use.
I bring several rifles and lota of ammo for each one. Hard cases for all of them except one that goes in a soft case behind the seat(unloaded of course). I bought one of those metal toolboxes that rides in the bed, resting on the bottom of the bed, not the rails. All the rifles save one go in there, along with shooting rests and cleaning rods. This type of box makes a dandy rest to shoot off of too, but some care and forethought is necessary when placing your rig in the feild to best make use of the truck as a shooting platfom.
Scoped rifles go in padded cases arranged so they rest on their narrow sides, with the scope up. The ammo goes in GI ammo cans, packed loose in Gallon ziplocks with newspaper wadded on top of the sealed bags of ammo. About 400 rounds of 223 fits into a 30 caliber can this way. It's a good idea to clearly label the contents on the top of each can, you can go nuts looking for a load if you don't.
All the stuff we bring for 2 guys fits comfortably into the back of my full-size ford, but there ain't much room for anything else. When I get to where I'm staying, everything but what I'll need for the day stays in the motel room. Still a recipe for chaos unless you stay reasonably organized, this dovetails with the safety issue too. Those feilds look pretty smooth but they ain't. You want your stuff secured before you go driving across the prarie.
Lately, I've been pulling a small lockable trailer for my stuff, it takes the pressure off having to fit everything into the pickup bed. Also a great shooting platform since it was purpose built for this. The Top is 4x8 and is just the right height for shooting over while standing. The top is at 48" when the trailer is on level ground. It's divided internally into a 3-foot and a 5-foot (rear) section. Access to the front compartment is by a side-opening door on the driver's side. The rear opens by a drop gate. Guns and clothing, etc can go here but I think rifles travel better in the cases wedged into the truck box. If there's only 2 of us the trailer stays at the motel until it's time to relocate or head home.
