My favorite piece of gear is the bag all my stuff is crammed into. This isn't some fancy bag with a cool gun logo on it, but it was designed to carry heavy tools. It has plenty of pockets and is sturdy enough for me to carry all my gun tools, cleaners, solvents, lubes and even ammo. I wish the weapons industry would take a good look into this style of "range bag" instead of the cheap flimsy powderpuff range bags that are on the market today.
I was on a military rifle team in 1958. We had a carbide lamp to blacken our sights, a shooting mat, left hand glove, shooting jacket and a spotting scope. Ammo was issued when we got to the range. Now days the bed of my pickup is full when I go to the range.
I have two fishing tackle boxes with cleaning gear in one and tools and parts in the other. A cleaning rod case made from PVC pipe, portable computer (log book & ballistic program) wind gage, electronic ear protection, Front and rear rests, various ammo containers, hard and soft gun cases (depending on where I'm going), spotting scope, chronograph and I'm sure there is something I missed.
My little Ranger won't hold all the stuff I "NEED" for a prairie dog shoot.
