Nothing special In regards to storage. Mine are all just kept on a shelf, grouped by what rifle they fit. Little ones, like 10/22 are kept with their ammo.
I thought I'd mention labeling mags, not the bins they're kept in, but the mags themselves. It's something I recently picked up on, and I think is a really useful idea. I number each mag with a sharpie or paint marker in an inconspicuous place, on the base or spine. If you happen to have a malfunction at the range, take note of the mag number, maybe even wright it down if you keep notes. You may find that you keep having problems with the same magazine and can repair or replace it as needed. A couple weeks ago I was shooting my AK and had a fail to feed. Not sure what happened, but I made a quick note "1 FTF mag 3" in my notebook. I'll keep an eye on that one in the future.
