I picked up a used Mec 9000 Friday. Its going to make reloading shot shells a lot faster when I learn to pay attention to what the machine and myself are doing. When its working, its fast, really fast compared to my old 600Jr. But when it glitches....what a mess. Sometimes it doesn't drop a primer or the primer doesn't drop in the correct die and not only does it jam but it drops powder in the primer pocket die and the mess starts. I know I need to keep an eye on what the primer is doing but sometimes you just let it slip by. You sure don't want to forget to insert a wad either. Ask me how I know this!! LOL! I think when I get trained its going to be just fine.
