Ohhhhh do i have some tips! I will preface this by saying that i got a very old pro1000 for $90 as it was “broken”
Stripped it down, gave it a total clean and grease and put it back together and it worked
Issues i had afterwards.
Primers: flipping and going in sideways.
Cause: the indexing rod has to much play causing the primers being knocked over on the pin as the shell plate indexes.
Fix: remove top plate and wrap electrical tape around the tip until it can move in the top plate but there is no wiggle in the rod
Primer tray not allowing primers to slide down the primer feed tube
Cause: couple issues, the mouth on the primer tray edges need to be rounded out to allow a freer flow.
Fix: dremel out the mouth of the primer tray.
Cause: primer feed tray not allowing primers to slidefreely.
Fix: the primer feed tubes are a two piece olded plastic and isnt smooth and had burrs. Sandpaper the burrs out and then smooth out the tray. After which use graphite grease to line the tube tocallow flow.
Press indexing aggressively causinv powder spillage
Cause: on station 3 on the shell plate there is a detent ball and spring. When that is activated the shell plate shakes
Fix: reduce the size of the spring. Eg cut one ring off. The press will index but not as violently and wont spill powder from the case.
I am sure there were other things too that i did but these were the main ones i made.
On the primer feed tube there is a point where gravity will no longer work and it wont feed primers anymore. The fix is to ensure you keep it filled with primers.
Dont run the press to fast either, i can easily churn 200-300 rounds and hour without breaking a sweat. I have a mr bullet feeder but i do. Ot use it.
I visually check powder levels in each case prior to putting in the projectile.
Edit: get rid of the chain that manages the powder throwing and replace it with a spring. I found an old spring in a box in the garage.
I also use clothes dryer scented sheets to remove static charge in the powder hopper… also helps to draw away moisture.
