When I go to the indoor range, I use a small bag big enough for 1 - 2 guns, couple of boxes of ammo, ears & eyes, and magazines.
That is a fair description of my "range bag". But it also serves as the standard bag for outdoor ranges and desert/mountain trips.
It is a
Cabela's bag. -Well, one of
many that I own. (Luckily, all were
given to me as gifts.)
I can fit 2-3 handguns, a few magazines, 2 sets of electronic muffs, 2-6 boxes of ammo (depending upon cartridge and what else is in the bag), and a few small tools. I ALWAYS leave at least one box of .22 LR in the bag - just in case...
In the outside/top pockets, you'll find a lens cleaner, staple gun, staples, tape, a Swiss Army Knife, a .35 caliber bore snake, an oiled rag, ear plugs, pens, markers, a mechanical pencil, an audio cable (for listen to music in the electronic muffs), a spare battery for red dot sights, spare batteries for the muffs, a pair of insulated leather gloves, and bags for picking up range brass. (And probably a couple other small items that I'm forgetting.)
...But I usually haul all of my ammo around in an ammo can, which keeps the bag from being packed to the gills.
I have a separate, much larger "target" bag that has another bag inside it full of targets. In addition, it holds bags, rests, bipods, more tools, more rags, a towel or two, various bags, Sudafed, Tylenol, Benadryl, Rem-Oil and Slip-2000 wipes, string, twine, 550 cord, instruction cards for some of the weirder scope reticles that I use, more ear plugs, a spare AR magazine, a spare Browning Buckmark magazine, a few bandaids, and some duct tape (I hate duct tape, it really shouldn't even be there). Some items are removed and left at home, if they won't be used (such as some bag rests, or the bipods).
The big bag can be packed with another 4-8 handguns; or 10-20 boxes of ammo; or the chronograph's tripod and 3-5 boxes of ammo and one or two handguns. ...And turned into a 70-pound boat anchor.
The chronograph has its own bag - identical to the 'standard' range bag.
My black powder rifles have their own range bags. (One is .50 cal, the other is .54 cal. It really helps to keep things separate. But it's also nice to not be hauling all of the extra crap around when only shooting one rifle.)
My black powder pistol has its own range bag.
I have a range bag dedicated to magazines. It serves as the overflow bag, with the applicable magazines for the trip, when I can't fit all of the handguns in the other bags.
And, more...
Basic concept:
I have ONE "go-to" range bag that ALWAYS goes.
Everything after that is contingent upon what's going on the trip, and what's happening when I get there.
I nearly always pack the day's/trip's ammo in an ammo can (or three), rather than the range bag(s).
Even the big "target" bag doesn't have to go if it's just a quick trip with 2-3 handguns. I pull out the target bag inside the big target bag, and head on out...
Oh! A note: When I'm talking about how many handguns I can fit in the bags, that's in reference to them being in "sock" type handgun storage cases, such as those offered by
Tourbon. In proper pistol cases, the number is easily cut in half. With no cases (the humanity!), the number could be increased by 50% or more.
