You're asking for ideas....
If it were mine (sigh) I would use more of the space. Suggestion below.
This is an autocad drawing scaled to your dimensions converted to a jpg.
Space bench to bench is 4'....plenty for you and a friend to reload in. Offset your lower cabinets enough so you have some room for knees using a back rested upholstered stools on wheels.
And yes madmo44mag, I agree with you, ain't no reloading room too big!
I could really enjoy this one though.....
BTW, the locations where I show "posters,"
are obviously good places for light as well...I'd suggest glass block windows....you get the light without anyone being able to see your business....they're more secure than a plain window as well....but then you lose your posters. The wall where the table is could also be glazed, posters, or more cabinets or shelves.
Merry Christmas!!
