Detailed Description

Winchester AA-HS 12ga 2-3/4" once-fired hulls (100/bag)

The NEW Winchester AA hull (referred to as High Strength or "HS" by Winchester) is a three-piece Reifenhauser type design. It consists of a brass head, an inner tapered base resembling a plastic cup and a straight length of extruded plastic tubing.

AA Architecture

The AAHS averages 2.7" in overall length. The distance from the mouth to the top edge of the inner-base cup is 1.9". This allows for a maximum wad length of 1.4" (with a 0.5" crimp depth) with a bit of wad compression. (Note: Wad compression does not consist of ramming the wad into the hull with thirty pounds (or more) pressure. Minor wad pressure of no more than ten pounds should be required.)

Winchester advises that the original Win AA and the new Win AAHS hulls are interchangeable. In the general sense of speed and pressure this may be true. However, there are some fit and finish concerns that require attention and different, accomodating components. At the base of the AAHS is a .020" thick rim edge where the inner-base cup meets the plastic tube. The ridge catches the gas seal of many types of wads, thus stopping the wad from progressing deeper into the hull. This prevents the gas seal from seating directly on the powder, which is required for proper load combustion. For this reason, the AAHS requires new loading information, outlined here with specific wad recommendations.

In BPI data: 

"Win AA" or "Win AA-old" refers the the original, tapered AA hull 

"Win AA-HS" refers to the new, three piece, High Strength hull

ONCE-FIRED HULLS STOCK:
We try to keep once-fired hulls in stock, but sources for used products can be unreliable at times. For value and reliable stock, we recommend that you also look at new/primed hulls. Because they are new, they will give you more loadings. Because they are primed (and there is no Hazmat charge on primed hulls when shipped in the continental U.S.), you save on your primer costs too.

Good shell for multiple reloads. 7/3/2017
Ive been reloading these now since the Remington STS are very hard to come by. My experience with them is very satisfactory, they crimp and fold very nicely and consistently, I have reload same batch over three time and only a few get damaged and discarded. I would keep getting them since they get the job done. I reload 7.5 shilled shots using red dot powder and love them. I will recommend them 100%.

I purchased five hundred of these AA-HS and had only twenty five unusuable. That was pretty good. Strong tapered shell for light loads no complaints.
