I use small plastic boxes made for keeping soap in my travel kit:
*tiny first aid kit: Bandaid, antibiotic ointment, sting neutralizer, aspirin
*tiny tool kit: Allen/torx wrench smittys, screwdriver with tips, small pliers
*tiny electrical kit: 2-AA, 1-9v, 1-2032 battery, tiny level (scopes)
A few dollars in cash and coins
Ziplock bag with paper towels, sunscreen, bug repugnant
Screw together cleaning rod, couple of patches
Small can WD-40
Small Rem Oil
Notebook, pencil, Sharpie pen
Earmuffs, plus some plugs
Bore light flashlight, small penlight
RO hat
10x24 binos
Ammo, magazines, sometimes a handgun

The spotting scope, tripod, chronograph, and strain gauge system go in a separate bag since I don't always use them.
