I heard many years ago that the larger the reloading bench, the more clutter it collects. On the other hand this does not have to be the case if your tidy about putting your stuff away. That being said, I have a workbench that supports a 650 at one end, and a 550 at the other end. I like enough room in the middle to clean my firearms if I choose. I even have cabinets above my 650 case feeder. I had to remove the doors on it since the doors would not open.
