    Have Mec 9000H. Primer drop, drops primer every time. The problem is that
    every one in ten times, the primer jumps out of the carousel hole as the carousel advances. Anyone else had this problem? Thanks.

    Clean out the re-sizing die. There may a piece of shot flattened between the fingers. Hap

    Hap,

    Why would a piece of shot stuck between the finges of the collet cause the primer to flip?

    Collet might be a little tight, back it off some. It's releasing all at once instead of gradually, causing the primer to flip.....GOOD LUCK

    A powerful magnet attached to the base of the loader will stop MOST of the primer flips. I got mine from an old motor that was being scraped.

    That being said, if there is any powder in the primer seat, it has a better chance to bounce out.

    I think what Hap is referring to is the possibility that the resizer is hanging up just a bit on the up stroke, then snapping just enough to cause the primer to jump.

    I have found that the problem is corrected with a little anti-seize grease on the outside fins of the collett. Don

    Why do only 10% flip? Is the collet sticking only 10% of the time? I've also read on TS.com that the position of the nut that holds the fingers can be responsible for the jumping primers. Any thoughts on that?

    I suspect they are all jumping, only some jump enough to flip. Flip a coin 100 times. Why does it come up heads sometimes?

    Alamo check to see if you have lost your index ball its located on the back side of the square upright it is held in place by a metal clip with a clip on it my loader did this. I must have lost the ball cleaning it replaced it now its ok

    2 things I found out on my 9000 when it was new. one I pushed a little on the primer tube to align it better, two on the down stroke, when your all the way down dont snap the handle up as soon as your down hold it a split second and you will see more primer stibility

    A suggestion I received from knowledgeable Mec repair person was to take a dremel tool with the sanding drum or fine stone on it and gring away at the collet just under the hole of the primer seat. Also make sure the collet is clean and properly lubed. It has solved my problem. Jake

    Chip, the primers won't fall in the exact same place every time on the carousel when they drop. Possibly the one's popping out are up against the carousel side and get more of a boost when the fingers pop?

    Mine was popping and I had that same problem a long time back too. Lubing the outsides of the collet helped some but that click was still there. I found a piece of shot flattened so much it looked like a flake of powder! Once I cleaned the bottom of the collet with a bent dental tool and blew it out with compressed air, the problem vanished!

    I have seen this from two sources. 1) The resizing collet as many have mentioned above. 2)The primer may be dropping a tad late. If the primer is still touching the feed tube as the tube starts up the primer can jump. Bend the tab that pushes the bar that drops the primer. A small tweak is usually all that is needed to get the primer started a little sooner.
