Howdy! First post here...
My range bag usually contains:
pen
Sharpie (great for marking stuff)
Tape for holding up targets (don't like staples, always manage to puncture myself with the ones other people leave behind
)
Set of little screwdrivers
Set of larger screwdrivers and hex-head tips (a bit redundant, eh?)
11" of 1/4" dowel rod (in case of a squib load)
Shoot-n-see patches (squares, great for patching gently used targets)
speed loaders
extra ears
extra eyes
ear plugs
extra targets
paper plates (these came in handy on a few occasions when I took my range bag to other functions. The folks where I was at were eating something...cake maybe...and I was the only one who produced plates from their bag. Of course, mine had circles drawn with the Sharpie on the bottoms...
)
Some of the other ideas have been great!
I'd like to add:
band-aids
tweezers (I've gotten splinters at the range where I shoot)
wet-naps for cleaning your hands after shooting lead - can get 'em free from a BBQ place - a win-win situation
Rats...now I'm hungry...
