You use an LNL?
How many rounds in a row can you load without having to stop to fix a misfed case or move the primer shuttle into place?
Did you ever get a granule of tumbler media in front of the primer shuttle then have the primer seating anvil shave a bit of material off the inside because of the misalignment? How about broken edges on the cheap die cast case feeder parts that cause balky case feeding? How often do you have to poke a case into station one because it didn't quite feed all the way? Any log jams at the top of the case feeder that makes you stop and pick them out of the funnel? Did you get the worn out dent in the aluminum casting under the primer seating anvil that made it necessary to drill a hole to insert a steel plug? How many primer seating anvils and shuttles have you had to replace? How many springs?
I got sick of maintaining the machine.
Even when it was "right" I bet I couldn't go a dozen pulls of the handle in a row without having to stop and futz with something.
I loaded well over 100,000 rounds on mine (maybe over 200K) and it got so worn out that it was useless to me. I called Hornady and asked them if they had a rebuild program like Dillon. They told me to buy a new press.
So I did. A blue one. Now I can load up the primer tube, and pull the handle on the 650 100 times without having to touch anything.
