I primarily load precision rifle, with short dabbles into pistol. I keep threatening to buy a Dillon Square Deal to pump out 9mm, but can't get the economics to work when ammo is so cheap right now...
That said, here is my setup, in a decommissioned hot water heater closet in our laundry room:
Forster Co-Ax, Prometheus Gen 2 powder measure, and various other tools. Not pictured is a separate cabinet that houses my powder and primer stores. It's pretty efficient.
Assuming prepped brass, which is done separately via stainless tumbling media and a Giraud trimmer, I can load a rifle round...accurate to the kernel of powder...about every 8-12 seconds. The Prometheus is expensive, but amazingly efficient and accurate.
