    I am reloading AA Shells/Alliant Unique/Win209/Claybuster CB1034-28.

    I am getting inconsistent crimps. 1 or 2 good shells then one that is crushed. The crimp looks good on the second to last station as shown in the photos.

    Is it the last station or a setting in one of the earlier stations?

    cabman, I believe the problem is at station five. Station five consists of a two part crimper; the crimper die, and the crimp punch.The cam adjustment affects the crimper die. It looks like the crimp punch is contacting the folded case mouth before it is adequately folded down.I would leave the cam adjustment set as it is and raise the crimp punch 1/2 a turn. Lowering the crimp starter may also help as it may leave the folded case mouth low enough that the crimp punch contacts it a little later in the down stroke.

    ps, There is a gentelman that posts in the reloading section of shotgun world. He goes by the handle of "Curly No Hair". He seems to have a very good working knowledge of mec loaders.

    Looks to me like the middle hull should have been sh!t canned and the edge of the right hull was hit a glancing blow by the final crimp die because the shell was still wobbling when when you cycled the loader.

    my guess would have been the body of the crimp die was set too low

    Do you ever get wrinkles at the base of the hull?

    Shells look a tad full before crimping as well. Did the wad pull back out in the upstroke or is that compressing the wad column in crimp stage?

    Maybe too much powder volume? I use B19 in AACF and REM STS hulls
