This is difficult to answer, because I don't have one single answer... it all depends on what I am doing at the range that day.

If I am planning to only shoot my ARs, I take my my AR bag that holds two rifles and has pouches for magazines, small cleaning kit, eyes and ears, etc. Usually has an AR in 5.56 and a .22lr AR. Magazines are pre-loaded and ready to go. Drawback to this bag is that once it is loaded, it is heavy!

If I am planning for a pistols only day, I pack everything in my range bag.

Some days are shotgun only, on the skeet and sporting clays course. Those days are usually shotguns in cases, a couple of cases of shells, shell pouch belt, foam ears on a string attached to back of ball cap and sunglasses.

And on days we shoot everything, the back seat of the truck is full of long gun cases, both hard and soft, range bags, ammo cans, coolers... looks like we are moving in.
