    I am having a problem with some crimps on my MEC 9000G, When I load STS or Nitro hulls, the crimp is just fine, but when I load AA's or Gold Medals, I cannot get the hole in the center to close up. I have the cam adjuster down as far as it will go and it closes up the Remington hull just great, but not the others. I am out of adjustments, any suggestions? Mec advises that it should be working if the cam adjuster is all the way down.

    Might try closing up your pre-crimp a bit. MEC says to get the hole on the pre-crimp station to be about the size of a pencil eraser. The AA hulls are a tick shorter than the Remington, so it takes a bit more pre-crimp to get them to close the hole up completely on the final crimp stage. Hope this helps. Garrett

    Oscar,
    You may just be out of luck ... with your MEC. With my machine, I found that I needed to drop the main crimp die down ... further than the threads on the shaft would allow. I actually took the main crimp shaft in to work ... had it weld built and re-machined ... in order to get the crimp die to effectively "reach" further down. Solved my problem - I get very nice crimps with AA now. In fact, I would daresay the crimps on AA seem more consistent than STS.

    For the AA hull, use the brown Downrange DR AA wad and your problems will go away. As stated above the AA's are shorter and this wad will give you more room for shot. Line up some empty STS's and AA's and put a straight edge across the top and you will see the problem.

    blueskyshooter, I would be very interested in a picture of your problem. I have never had to extend my pre-crimp any where close to the end of the thread. As a matter of fact I have been having some good luck with the old style pre crimp which use a brass star encased in a metal collar.

    I tried the original Winchester AA wad and the Rem TGT12 wad. The Winchester wad is shorter than the TGT, so i thought that would work but I still have the hole.

    I had the same problem and solved it with changing the wad. I used to use the Down Range figure 8, for Remington and AA hulls but they left a hole on the AA's. I don't like adjusting the reloader for different hulls, so I just changed to Down Range XL 1 1/8 blue wads for all my hulls. No more open crimps on AA's or any other ones for that matter. This one wad works for all.

    Cal,
    Its the main crimp station that I modified ... not the pre-crimp. I set my pre-crimp to close the hull just a tad smaller than a pencil eraser.

    I did as claysmoke and Blusky shooter suggested and lowered my pre crimp down a bit and it solved the problem. Thanks You two for the suggestion and I did as emmylou1 suggewsted and made sure I had less than a dime thickness for the crimp itself.

    I want to thank everyone for all the help! I am now good to go with the AA Hulls. I have several thousand of them and did not want to have to get rid of them.
