Still building mine, but here's what I have so far. Imagine peghooks on the back wall and sidewalls for reloading tools, as well as another powder measure behind the ammo plant for the single stage. I got the stand in the mail already, but still waiting on the measure itself.
The cart is from Rockler, I think. It's wheeled, when I'm not loading I plan on wheeling it into an extra bedroom out of sight. Garage space is a bit of a premium.
