My one problem with the Co-Ax - it was a very effective press, very fast to change dies and very little issue about shellholders (unless you load a caliber which requires the second set of jaws, which I did), is that I learned to load on a Rockchucker. So I learned the case shuffle, where you pick up the new case between left thumb and forefinger, and take the last one out of the press with left forfinger and middle finger (it's harder to describe than do). This minimizes the motion involved. But it requires using the right hand on the press handle and almost madates sitting directly in front of the press. The Co-Ax's handle comes down along the centerline of the press, so I had to sit off to the right and then my arms crossed with every handle stroke. Very awkward. So I sold it and replaced it with a Redding Boss, which did everything I needed it to do at the time and was comfortable as well.
That was before I got my first 650. Boyoboy, what that an eyeopener for production speed.
