I keep loaded ammo and powder and primers locked up in cabinets. Also keep things like extra scopes and scales and my Magnetospeed locked up in a cabinet. Guns are in a safe, no ammo in the safe. I even keep bullet moulds in the safe, as that happens to be a handy place to store them. With the last change from NRcan, you can use a metal cupboard to store powder and primers, as long as the shelves are painted, may be an idea to put the cheap rubber mats people use in RV cupboards on the shelves as an insulator against static charges, and don't have the cupboard under a heat outlet, keep powder cool. I had the material for a powder cabinet, so I built a wood one, just used regular hardware on it. Just be aware, an apartment is restricted as to a different limit of 20kg (25?) of powder/ammo, and no 8lb bottles, have to be 1lbr's. Weird quirk there, but, is what it is.
I found having one of the swinging/folding/telescoping bench/desk hobby lamps with a magnifier to be handy, have one on each bench and one on a rolling stand, with LED bulbs. Basic overhead lamps seem to create too many shadow areas where I want to look.
And if you are using a beam scale, build a shelf at eye level to put it on.
