RE: reloading bench layout
Never had one. Not a permanent one. Didn't have the room; smaller home; no basement and children took up a good deal of the housing space. (Piano/computer among some of the space takers)
By the time they were grown, I didn't have any interest in a big reloading center. It's a great system for someone in an apartment or for whatever reason, can't fit it into their housing situation.
So all my reloading equipment is hidden. The "bench" is a portable Black & Decker Workmate bench. I use the frame and bolt a 5/4 x 6" board to it. Bolted permanently into the board on one side is the RCBS Partner press and on the other the base for the RCBS powder measure. Set it up in the family room; particularly when no one else was home. The workmate goes in the shed for storage, and the board goes in the furnace room closet.
My lead bullets and powder are kept in a closet. The dies, tools, powder measure, jacketed bullets, primers, scale, etc are kept in a couple of large tool boxes. The tumbler goes in its original box and is stored with the tool boxes in a shed. I have a couple of smaller, different color, tool boxes to hold the reloaded ammunition.
I never reloaded every week or every month, so I never really needed a permanent place. And it never bother the wife that I didn't need one.
Guess I'm too old to really want a full scale reloading area, now.
For a young reloader, in a small home or apartment, it's a nice option.
