Pick em all up and toss the ones you dont want.
Really though, unless everyone else is shooting Estates or Rio, there isnt a good reason NOT to pick them all up.
Remington STS hulls, along with their ribbed gun club and black economy hulls all load the same.
Winchesters newer AA hulls arent as good as the old ones, but again, I pick them all up.
Personally, I load all the hulls with the same components. Ive never had an issue, though I did go through all the data to make sure I could get away with it. Velocity doesnt vary enough to matter in the load I use.
Plus, its nice to be able to have a bunch of shells you dont have to worry about picking up if its snowing, or they go down an embankment, etc, like when shooting sporting clays.
I use 18gr of Clays, Win 209 primers, and CB1100 wads, with 1oz of #8. Its about 1200 fps. They all cycled my 1100 when I had it, and my Dads Super X 1, and older 1100, and my Brothers 11-87.
The club I used to shoot at had a lot of guys buying the Estates. A few of us even loaded them for a one time throw away shell. They worked just fine too, but I have so many others, I threw most of those out.
