Good info right there, thanks for posting.
All the pics show the lever about vertical in the ram down/lever-up/start position and others have complained that the long arc of the lever puts it too low when pushed down.
Your: "Rotated back as far as possible without the lever hitting the bench" position puts the lever higher up when at the bottom position.
Sorry to hear that the ball (and your hand) could contact the case slider if you shorten/slide the lever down into the mount.
I was thinking a shorter lever would increase the "feel" of the primer seating and eliminate the chance of dumping powder into a case that has no primer AND shorten the arc of the lever.
