After about 20 years, I'm getting back into reloading. I found that I have a box of about 100 Win hulls marked AA. These have a separate plastic basewad but are not marked as "HS." About half of them are marked "Heavy (3-1 1/8-8) and the rest are marked "Light (2 3/4-1 1/8-8). The head stamp reads "Winchester 12ga AA." I guess I've had these hulls since about 1995.
Lyman's #4 gives load data for "Win Polyformed Plastic Cases Plastic Basewad" and "Win Compression Formed Plastic Cases."
Lyman's #5 gives combined data for "Win HS and Compression Formed Plastic Cases."
My question is whether I have HS hulls or something else. They are definitely not one-piece CF hulls.
