Is there any difference between the grey and red Winchester AA hulls, in terms of reloading? I've been told yes, but I don't trust the source. If there is a difference, what is it. Also, if there is a difference, where can I find reloading info for these hulls?

 

[Case]

So long as you're referring to the newer AA-HS hull there's no difference at all that I've noticed. Nor was there any diffeence in the old AA compression-formed silver or red hull.

You'll find load data for Winchester hulls on any of these powder companies' load guide pages:

Hodgdon Shotshell Load Data

IMR Shotshell Load Data IMR, an acronym for Improved Military Rifle, is now owned by Hodgdon.

Alliant Shotshell Load Data (Formerly Hercules)

Winchester Load Guides in PDF Form (This company can't seem to get in step with the rest of the industry by offering online reloading data for its components, so you'll need Acrobat Reader after you download the PDF files.)

There is no difference. They are interchangeable.

Thought so. As far as I could tell, they were different color due to the fact that it was in celebration of winchester anniversary. They wouldn't create a new product line to create shells for one year. Gracias compadres

The grey shells aren't anniversary shells. They are a standard production item. They denote some of the heavier shells in the AA lineup. The rhino rocker Super Sport loads are silver as are the handicap trap loads.
