    Any ideas on how to correct the crimps I'm getting on my 366 Auto?
    The finished shell looks great, but there is a slight opening in the center of the crimp(about the size of a size 8 shot). The depth of the crimp looks close to factory. Thought I'd ask before making adjustments.

    If you go on the Hornady web site, under manuals, it gives you a complete run down on the adjustments of the 366.

    I'm with old folks on this one...I'd come down on the start crimp a bit, and then maybe come down a bit on the final crimp - maybe 1/2 a turn on the screw in the middle of the crimp die. No more than that....

    What kind of hull are you using? Hornady came out with a new start crimp die a few years back, as I recall, for the new AA hulls.
