    I'm trying to load a 1 oz load into the new style AA hulls using 17.5 grn Clay Dot, the Pink Claybuster WAA12SL wad and #8 shot and I can't find an adjustment that will close the hole in the center of the crimp. It's pellet-size. I've made all my adjustments from my baseline settings which produce perfect crimps on anything Remington in both 1 oz and 1 1/8 oz with only a wad ram alteration.

    I've tried:
    <blockquote>
    (1) increasing seating pressure on the wad
    (2) both raising and lowering the crimp starter 1/16 inch (not past a 45ยบ angle)
    (3) lowering the crimper 1/8 and 1/4 turn with the crimp starter in both its baseline and altered locations
    (4) increasing the spring tension on the crimper by 1/2 and 1 full turn of the nut
    (5) decreasing the spring tension on the crimper by 1/2 and 1 full turn of the nut.</blockquote>

    I'll occasionally get a good crimp but the majority have a hole in the center that ranges from noticeable to #8 shot size. The hulls range from fired once to reloaded twice but are separated by age so all in a batch have seen the same use.

    Any ideas??

    Lower the crimp stater a little at a time until the hole disappears. That squeezes more plastic into the middle.

    It is a lack of space issue. On my Mec Grabber if I did get the hole adjusted out of the crimp the hull would buckle. Try loading 1 oz loads in the Win AA HS hulls with Downrange Manufacturing wads, the DRA-12 Pink and the DR-XL-1 Neon Green wad are shorter than the Win AA 1 oz pink wad. The Win AA 1-1/8 oz white wad reloads better for me in the AA hulls for 1 oz loads than the Win 1 oz pink wads do. The Win AA 1 oz pink wad loads good for 7/8 oz loads in the Win AA hull.

    Has this been a "forever" problem or since a component change?? IE different Wad???

    I have had the same problem with the AA hulls in my P/W 900. The only way I have found to fix the problem is to dump every AA hull that I had and to use only STS or Gun Clubs. Problem solved!! Ed

    I've already had the starter down to the point where the crimp was folded past 45 degrees and I remember a couple of warnings to not go past that point.

    <blockquote>"Has this been a "forever" problem or since a component change?? IE different Wad???"</blockquote>

    I have 2 formulas that I use to load 1 1/8 oz in the AA hulls; both use the Figure 8 wad but different primers and slightly different powder weights (16.8 grn and 17.3 grn, both Clay Dot). I don't have a bit of trouble with the crimps of these loads. The problem surfaced when I decided to try a 1 oz load and the WAA12SL wad to stretch my shot supply a bit. I looks now like it might be the wad. I'll stooge around and see if I can find a formula that uses the TGT wad. I will also look into using the WAA12 wad for the 1 oz load. I don't have a ready source for either DownRange or Duster wads that doesn't involve shipping costs.

    Thanks for the input.

    Mike i load with a 900- 2000 what i have found is the factory sets the wad ram for 1 1/8. when loading 1 ounce you need to adjust the wad ram up 2 to 3 turns plus use a factory wad. this will help you on getting a good crimp. MAC 111.

    Thanks...I'm familiar with the need to adjust the wad ram when changing shot weights. I also adjust it when changing from one wad to another within a weight class. In fact, the ram is probably the most oft-adjusted thing on my press.

    Forget about the 45 degree talk and lower the crimp starter. I'll quote the PW owners manual. "If there is a hole in the center of the crimp at the final crimp station, set the Crimp Starter 1/16 inch lower. This will force more plastic or paper towards the center of the crimp and the hole will disappear."
    Nothing about 45 degrees. I set the crimp starter to get a good crimp on AA's and everything else loads fine. I load on a PW Platinum, no holes. Apx 30 degrees

    Ditto --- what jerry said ; plus , set a bunch of empty cases on your bench and check for variations in OAL to see if that is possibly contributing to your frustrations .
