Not too many bench rest shooters here, huh?
Rubber tub with a windage-topped front rest and three or four sand bags, a towel, some targets, pasters, a couple of 6"x6" 1-inch boards, powder for the bags, etc.
Nylon bag w/ shoulder strap that holds a hard case for 2 scoped rifles.
Big bag with the usual tools and cleaning stuff for rifles and shotguns, ears, eyes, targets, etc.
Another bag - what most of you would call a range bag - with handguns and handgun stuff.
Canvas ammo bag (or two).
Canvas ammo bag for the spotting scope if I take one.
I even carry a back-up stapler.
Oh yeah, and a cooler in the car for my lunch and maybe supper.

P.S. - If I'm just going for an hour or two I use an old Zenith laptop bag that will hold two pistols, ears, eyes, ammo and targets.
