Sorry if I added confusion, the current main line Estates are to be made in the states and in my experience are very good shells.
I have 180 flats ordered for competive shooters and they like them for recoil, preformance, and cost. Most of these guys do not reload and can afford any brand. Also if you make a serious price check AA is typically +$2/box and STS is +$3/box. A supplier who helps shooters needs to be rewarded. When it comes to breaking birds AA and STS are not worth an extra .50/box let alone two or three dollars.
