One other little tid-bit of info.
While the AA CF and HS hulls do in fact use the same load data, there is a small catch there. The new HS case in fact has a tad less capacity than the older CF cases.
So if using the AA HS cases, and using the newer version of the WAA12F114 wad, you have lost capacity in two places. The case has less capacity to begin with, and the wad is taller, leaving less space for the shot. Now the case is too full and the crimps are popping open.
This is akin to placing 6 lbs of crap in a 5 lb. bag.
To ease this problem, use the Down Range version of the WAA12F114, which is the DRA-12 Yellow, and is an exact clone of the original W/W wad, and is a tad shorter than the new version of the w/w wad.
Then, if necessary, cut the shot charge by 8 or 10 BB's and gain some more space, to where the crimp has enough room to properly form.
In this way, all components will fit in the case, and not put upward pressure on the crimp, which in time will force the crimp to bulge or even pop open.
