Winchester still makes a red AA hull but I don't think it's nearly as good as they were ten years ago. Can't quite remember when they changed the plastic formula but everyone I know who loads complained. Hard to beat Remington STS/Nitro's
I don't load anymore but do save most of my STS's for friends.
STS's are the better hulls nowadays.
The old-AA Winchester-tooling and machinery was literally worn out by the time the newer HS-AA's came out. The AA first made it debut @1960ish.
Bag the Tinnchesters. Buy the Remmie STS instead!! In addition, Remington Game Club hulls while cheaper, load exactly the same way as STS's.
