Dear Brad;
You may consider that the reloading machine you have may be faulty, but since it works with the remingons... it could be that the AA's arent made to reload, my personal expeirance is that winchester loads shouldn't be reloaded.
For close 16-22 yd skeet use a skeet cylinder or standard cylinder bore, It will be hard to find these unless you can find a hunting outlet or something that has a wide variety of chokes.
hope i could be of some service.
