Winchester AA 12 ga. casings

hipshoot
For years & years I have been loading the AA casings using either the AA12 White wad or WT12 orange target wad. Never had any problems with the casing buckling till I recently loaded some of the new Winchester AA hulls. I tried backing the last crimp station out slightly but that still didn't help.

Do I need to use a different wad?

Do any of you switch back and forth loading the old & new AA's without any problems or making adjustments?

    This is not a new problem. It is typical with the darker gray casings, but not the lighter grey. I adjusted my loader to help, but it didnt completely cure the problem

    Is it typical with the red casings as well?

    The newer WW cases are thicker towards the base and require HS wads. They will not interchange.

    I load the new red AA hulls with no problem. Was getting a ring around the hull about 1/2" above the metal base. I had to lower the start crimp about a full turn and that seemed to take care of the problem.

    I load all the Winchester and Remington hulls with the same components and charges, I've been doing it for years with no problems. When the hull tried to fold when I first started out, I adjusted the shot charge by throwing less shot until I got the crimp I wanted.

    Thanks for the reply's.

    Grizz: What wad are you using? Did you cut back on a 1-1/8 oz.load?

    Yes, I think I put about 1 1/16 oz. of shot in the Claybuster replacement for the AA 1 1/8 oz wad. I use an adjustable bar, so it's easy to add or subtract shot and powder.
