I have no experience with the Big Boss, but do have the smaller Boss press on my bench. I load .32 S&W up to .30-06, and it does fine, but if you will be loading a lot of magnum length cartridges, the Big Boss may be better suited.
I have no complaints about my press, with the exception of the primer catch system Redding uses. The primers do not want to go into that little plastic box they provide, and I usually end up with as many on the floor as I do in the box.
My brothers Rock Chucker, and my dads Lyman Crusher press seem to have a little better fit and finish than my Redding, but functionality is the same.
