I have loaded at least 20,000 rounds with the 1000. If you watch the primer feed closely you will have no problems. Missing a primer once in a while is its weak point. I shot combat matches for quite a few years and it served me well. I shot on average 700 rounds per week. I had two of them set up one just for the 45 ACP and the other for 38-357. I wore out several of the little nylon bushings but they were dirt cheap. For the MONEY I know of nothing else in its class. Oh if you miss a primer it dumps the powder charge down into the mechanics and you have to take it apart to clean it out. Sometimes I could just blow it out with an air hose. When I reloaded a big batch I had my wife set there and watch the primer feed.
