Using a Winchester AA hull:

Let me start by saying I substitute a Ched 209 primer for the Win 209 primer, and I have not run into any issues. I have never tested for pressure differences, but FPS results have consistently been very similar.
This is a great hunting/long range load out of WIN AA hulls using an ounce-an-and-an-eighth of shot. If you are using shot sizes 7.5 or 8 or reclaimed shot, I highly recommend using the older AA hulls if you can find them because they are slightly taller, and give you a little bit more volume to hold the shot thus producing a better crimp and full closure.
You can avoid this problem by using Remington hulls for LongShot loads you can build upwards of 1500fps (seen my next post).
