Current appartment setup.
I started reloading in the appartment my wife and I live in, and I use a few different things.
For metalic reloading (45 acp, 9mm, 22 Hornet and 308), I have a frankfort arsenal collapsable reloading bench. I have my single stage press and powder measure mounted to the bench. This bench comes with two plastic bins, and I got a third from a friend, so I have plenty of space to move components around, as well as space for the brass block holding the brass that is ready for the next step. The powder scale and cartrige holder sit on a wooden "tv tray" next to the press. Very compact, and I can shove it all in the corner of a small closet if necessary.
For shotgun, it's a little easier. I have a mec jr in 12 gauge that my wife's grandfather and I built a mounting plate for. I got a 1/4 sheet of 3/4" plywood, and cut it down into two 12" by 18" pieces. I drilled holes that match the mounting holes of the press in the middle of one piece of plywood. From there, I put some carrage bolts in said holes, and carved out a little of the wood from the second piece (to make room for the bolt heads), and then glued the two pieces together with the bolts in place. Now, I have a 1.5" thick, 12"x18" base plate to bolt the press to. It's big enough that I don't have to clamp it to anything, but, as above, the whole thing can be shoved into the closet with almost not trouble.
Good luck, and Merry Christmas.
