Ypu guys better be carefull when making samiches and drinks with all this excess ammo in peanut butter and gotorade jars. I have a slim ammo can dedicated for 22lr on the shelf in the garage and load out all my amo into a milk crate for the range. Small cardboard boxes from mail order items campartmenatalize the box so it is easy to keep 9mm, 5.56, 308, 12ga and 22lr devided. And the mags are set up the same way in the same crate. This way I never leave mags behind and have ammo for verythign when I get to the range. It took some reworking to get it right and it is till evolving. I even have my field armorers kit I built in a fishing trinkets flat devider bin stashed along one side. It has a needle oiler full of mobil one and an eydroper full of morvel mystery oil. cleaning rods and end for all calibers, patches, pics, brishes, a min screwdriever with a doxen bits, a handful of allen wrenchers, front sight tool for AR and HK, ods and ends and pare parts. When we get to the range and set up I put the 22lr brick on the table for the kids and almost always they burn through 500 rounds in under an hour, but the day gets cut short or for whatever reason they do not burn the whle brick then it ges back in it's spot in the crate.
I know milk crates are not the easiest thing to get your hands on. But walmart, home depot, and the like sell some plastic work/storage totes and they are now carying smaller sizes not to much diferent from a milk creat witht he advantage of a wter tight lockable lid and no holes on thesides and bottom. This makes geting ready to go to the range and getting ready to leave a lot easier than loose boxes and a bunch of ammo cans to deal with. i used t do the ammo can thing but now it is me plus three or more most rang day. If it is just me then I just toss 500 rounds of 556 and 200 rouns of 9mm in a rifle bag with mags and guns and go.
Other than my set up, the quart rubermade containers makes a lot of sense as does the paintball tubes. Both are cheap and durrabl if you take a while to burn a brik of 22lr. I used to burn 2 bricks on any given day growing up. So sad that my kids can't do the same.
