I use one of the heavy canvas bags you get with ridgid tools at home depot. Ammo goes into plastic boxes in it, tools in another small box etc. Makes it easy to lay everything out on the bench at the range. I may have an extra one if your interested.
I use one that says Game Winner on it. Not sure even where I got it. Heavy Realtree camo Cordura. 2 side pockets, 1 front pocket, pocket in the top flap and a fairly large compartment that will hold a lot of shells.
most of the back seat of my truck and probably half the bed as well. Not may ranges here in quitman county so when i go i have to carry target stands, bench, and everything else that goes along with it.
