I have been reloading with a Lee Single Press for 2 years, with an average of 8000 rounds a year. Few weeks ago I decided it was time to upgrade from it.
After a little bit of research, I decided to go with the Lee Loadmaster. I ordered one. I received it. I put it together. I spent 4 hours adjusting all the stations. Then when it was time to run, well, the Loadmaster ran like a press should run.
But I believe Lee has been watching many hours of Youtube mods videos, because the indexing was already set, most of the contact parts were already polished and the primer loading arm was smooth. It even feed and primed my Sellier & Bellot primers perfectly. I still had to tinker a bit with the press, but mostly to get acquainted with it and put grease in a few places. I still think people not too mechanically inclined should stay away from it.
My 3 issues I have with the Loadmaster are:
The Auto Disk powder measure that came with the press is not as accurate as one should be. But there are aftermarket solutions to correct that.
The Powder measure chain. It works but its in the way, so I replaced it with a spring

This is the spring's size

2 of the press to bench attachments are too close to the edge of the bench, so I removed some wood out of the bench to offer more clearance for the ram and sat the press deeper onto the bench.

Other than those nitpicking issues, the press runs like a charm.
