Not too long ago I bought my first real rage bag.
Before that I used a surplus GI Musette bag from WW2, however I outgrew it.
State law here requires arms be kept in locked cases for transport and the old musette wouldn’t fit three MTM 806 hard cases.
New things seem to always require reevaluating the status quo, like what else I need to keep in my spiffy new range bag.
Targets? Yeah, all but the large silhouettes will fit and even those can be rolled up and placed under the bag’s handles,
Ammo? Plenty of room for a few boxes and even loaded mags in the —what do you call ti? Elastic loaded mag thingy?
Cleaning kit? it has been a long time since I’ve shot at a range with an adequate place for gun cleaning so I leave the cleaning kit at home unless I 'm shooting exceptionally dirty range ammo, then a Boresnake will at least take out enough fouling to keep me in business for the session, and of course a cloth for wiping down afterwards(I’ve long preferred a well washed cotton diaper for the job as they leave no lint behind.)
Coffee can? The traditional container for policing spent brass. Sadly doesn’t fit with everything else in the range bag, however I reload my brass and I always want to leave the range cleaner than I found it so so I won’t leave it behind.
Staple gun? A staple gun is always handy even at indoor ranges using backer boards which help keep targets from moving from the ventilation systems air currents. If you supply your own you won’t have to wait to borrow the range’s staple gun.
Ears and Eyes? For me, “eyes” are built in—I wear glasses, and “ears” don’t take much room. Even with my old small bag I’d loop them through the carry strap and be G-T-G.
Target pasters? Black and regular color masking tape are a class act. Nice to have but they’ve never been must haves for me and make your targets useful for a bit longer.
Tools? Neither of my pistols require specific tools for field stripping but I like the idea of having a squib rod and hammer. Shoot long enough and you’re bound to encounter a squib eventually, which will put you out of business until the bullet can carefully be driven out of the barrel, I can see where a screw driver is useful if you’re sighting in with adjustable sights,
Another item I want is a small note book and pen or pencil for, well, note taking and writing on targets.
