I am still looking for the perfect way to store them all.
I'm still looking for a good way of coding them (using sharpie on the condom), but I'm pleased with the storage I'm using. I got an old cigar box and put the tray from a box of bullets in there. If you've never seen them, this is a plastic tray with 50 holes (5x10) to hold bullets in a box. 9mm fits my cartos without the condom and larger caliber fits them with the condom. It makes it easy to organize and group. If I end up needing more than 50 I can easily add another tray to the cigar box.
If you're not a shooter, just ask around and find someone who is. They're probably
throwing these trays away (I was before
vaping). As for a cigar box, any cigar store will sell (or maybe give you) a nice cedar cigar box for about $2.
The box also leaves me room for juices, blanks and some misc supplies.
