    Anyone have problems with the crimp for 28 gauge shells on a Mec 9000g? It seems like no matter how I adjust the loader, I still get a bad crimp every seven(more or less)shells. Usually a swirl or fold that is not on the original fold. I use AA hulls. I have checked the wads and powder quantity. I have raised and lowered the start crimp. I have raised and lowered the crimp punch cam adjustment. Any thoughts? Neil

    Sounds like it is the hulls that are the problem. Have you tried Remington hulls? HMB

    What components are you using? Using the AAHS hull?? Are they the short versions?

    I have not tried the Remington 28's. The Winchester hulls usually last for about 10 reloads. I am using the AAHS that are underscored(the newest version). I am using 13 gns of Unique with Claybuster 28HS wads. Neil

    Is your crimp starter free to rotate? If it is not, it may be trying to start new folds instead of following the existing ones - but I would expect this to happen more than 1/7 of the time.

    If there is too much empty case above the shot I have seen the swirl. I noticed this when I got going too fast and did not notice that the shot was low and got short drops.

    I have loaded thousands with my 9000G and since Win lengthened the case the crimps have been wonderful - they were OK before but "flat" on the top because of the short hull.

    I will be up to the Shoot on the 22nd at Koch. If you don't have it worked out by then we can discuss it further.

    The AA and AAHS hulls vary in length. I sort the hulls and reload in batches of same length hulls. The MEC cam setting and pre-crimp settings have to be changed between different length batches. Also remember that the AA and AAHS use different wads. Bob

    Neil, take a good look at the mouth of the hulls before loading. Sometimes the end gets smoothed out and the original folds are completely gone. If so, they will not crimp right. As John mentioned, the crimp starter needs to be free to rotate also. Tony

    The short versions will measure ~2.600", some possibly less, make sure you don't have any of these mixed up in your stash. Longs will generally be ~2.675" and it's easy to set them up on a table and pick out the shorts.

    Are you using the CB HS"A" wads, the A makes alot of difference, if not you need to get some. They work the best regardless of short or long hull, but most definitely the shorts.

    Though not designed for them, I'd resort to the Dusters before continuing having to compress too much height. At least using 20/28 and Longshot, I can't tell any difference in using the Duster or CB, except the Duster will pattern a little tighter.

    Yada/Yada/Yada, yeah I know they're for the CF hulls, they still work and smash targets. Even 27 yard targets.

    Neil,
    Absolutely do not waste your time with STS hulls, they are junk! You will be lucky to get 2 reloads out of them before they start splitting around the mouth. Stick with the AA HS hulls, but look into the blue downrange wad with Universal Clays powder. I have been using this combination for several years without any problems. I had the same issues you have when I used Unique, that is why I did quite a lot of testing with various combinations before going with Universal Clays.

    I have loaded thousands of STS hulls and I like them. I give the AAs away! Try them both and decide for yourself.

    Ditch the HS wad go to the remington pt28 or federal 28sc and your problems will be over. I'll be glad the send you 30 bucks for say 1000 shipped but only if it puts your conscience at ease. 4andy10

    I ran into this last year and changed wads, powder, and hulls, nothing helped...like you say, every so often I would get a bad crimp. I was always adjusting, tinkering and fiddling around and I would 7 or 8 good, then they would go nasty.

    Check your cam, more specific, check the little roller the cam rides on...roll it around and check it good. Mine had a flake off one side it. When it was on the round, I got good crimps. When it was on that flaked off flat, I got bad crimps. Like to have made me crazy until I found that bad roller.

    I'm using up my old style AA, Unique powder, and Rem P28 wads. I've been loading some of those hulls for so long that they have names!

    I was having a heck of a time with unique. I was loading the OLD WW red hulls with no issues. When I ran out I was using both Remington and AA. Almost gave up loading 28 gauge.

    Ran in to Alliant rep at a shoot and asked him about it. He said that unique was made for the 20 gauge. Yes.. I know that there are published loads for the 28.

    He gave me a sample of the 20/28 powder. Switched and nevre looked back.
