I use to shoot nothing but AA compression hulls for all my Trap & Skeet reloads but to say they were the best hull ever made would be incorrect.
When Remington came out with the STS & Nitro hull just different colors. Remington has the winner in 12ga & 20ga STS hulls
In 28ga Winchester HS is the best sold today.
I had a few hundred AA compression hulls once fired and gave them to a friend as I got tired adjusting the reloader from AA to STS hulls, life is much simpler with just one style per gauge.
For Me Remington in 12 and 20 and Winchester 28ga.
