I am selling some hulls to help out a friend. How do you tell the difference between old and new winchester hulls both grey and red? I never load these so I am in the blind here. I want to be able to properly describe what I am selling
Lou, all of the new AA's since 2001 will have the separate plastic base wad in the hull. You can see it with a flashlight from the outside or inside, or slip your pinky finger in there. The first generation AA's did NOT have HS stamped on the head-stamp. All the new ones from about 2003-04 HAVE HS stamped on the head stamp. PM me if you want, I got pics of all of them.
Some of the new AAs have the box around he AA so that is not a reliable way to tell the difference. On the grays, the old style are more of a silver while the new style are much darker in color, more of a charcoal. On the red ones, the old style have sort of a dull finish while the new style have a shiny finish to them, very distinctive and the best way to separate them when mixed. The grays also display the dull/shiny finish distinction, in addition to the markedly darker of the new style.
The loading recipes are generally the same. The new style have a slightly smaller internal capacity and you need to be careful with the height of your components. In the new style, a slightly shorter wad is needed to prevent the hull from buckling on the final crimp. If you are going to load 1 oz of shot, consider using a 1 1/8 oz wad. Or, Downrange makes wads specially designed for the new AA wads that have a slightly shorter cushion section. I was going crazy trying to load the HS hulls with standard AA wads. My sanity came back when a switched to the slightly shorter Downrange wads.
