Free advice being worth what you paid...
1 - Primers
Federal 209 are starting to pop up with regularity on Brownells, Powder Vlley, etc. However, they are pretty proud of them.
Cheddite 209 are available much more consistently, and comparatively speaking, at a reasonable price. Ballistic Products seems to be a reliable source, and often runs a discount on shipping or Haz Mat. That being said, my LGS has them on the shelf right now. Shop around locally before you buy from an e-tailer.
Rio and Fiocchi have also started to appear.
I haven't seen a Winchester 209 for sale in a few years.
2 - Shot
Check with your local clubs about reclaimed availability. You may get lucky. If not, ask at the same clubs about group buys. Several guys can go in together on a pallet of shot, and save $$$. They may also be able to direct you to smaller vendors, gunsmiths, etc. who sell reloading components, but may not have the same public profile as the big name stores. I was shocked to learn how many guys within 100 miles of my house sell components out of a home shop. The bulletin board in clubhouse at my skeet club is a treasure trove of information!
Good luck!
