I have a Hornady LNL AP with the case feeder. It comes with 2 size tubes small and large. I load 40S&W and 10mm. The small tube measure .430" ID and is just slightly too small for unsized 40 brass. Some of the cases get sqeezed by the tube and get hung up. The large tube works OK but sometimes the cases tilt a little too much and dont drop properly at the end of the tube. A 1/2" ID acryllic tube would be perfect. I've searched high and low for acrylic tube like this but I can't seem to find it. Can anyone help?
