I've been happily cranking out .45ACP loads on my Lee Pro 1000 press with the Large Case Feeder, tubes, and case collator. I just got a new shell plate and carrier, and spare die turret to switch over to loading 9mm, and I'm wondering if there is any difference between the Large Case Feeder and the Small Case Feeder, other than the slide that actually pushes the case onto the shell plate. The feeder tubes and case collators I've seen for sale don't differentiate Large or Small, from what I can see. Getting a Small case slider and a straight Z-bar looks to be cheaper than getting a whole new feeder assembly, if that would work.
