I'm loading .44-40 on a Lee Loadmaster (will probably upgrade to the new Six Pack Pro soon), and for my purposes the Lee case feeders (which are universal to all their progressives) would be just fine, though I might invest in an aftermarket feeder with auto collator at some point. Problem is, the Lee case feeder tubes are just barely too small for the rims of .44-40, at roughly .515 ID and .565 OD. They'll feed .45 Colt fine with it's rim diameter of .510, but the .44-40 rim diameter is .517-.519. I believe .38-40 shares that head diameter too. Roy Bertalotto has a great article on his blog here http://rvbprecision.com/shooting/lee...-40-44-40.html on making some copper feed tubes, but I would love the lightness and most of all visibility of clear plastic. I could cut a slot window in the copper tubes, but it would still be less noticeable when brass ran low. I thought about reaming the factory tubes out with a drill, which won't leave them nice and clear but might work. I could add some of the aftermarket stabilizer clips to the four tubes for extra rigidity. I found a source for tubing with a near-perfect ID and very close OD here https://store.visipak.com/1-2-x-4-he...-plastic-tube/ but I am doubtful that I could find 130 other people that needed the extra. Anyone have any low budget ideas on this?
