Most shoot stuff like Talon or Yugo since it is widely availible and cheap. Accuracy is fair and its good stuff for getting to know your rifle with. A step up is something like Hunting Shack Munitions, better accuracy for about 50% more cost. Lots of folks are reloading military components with good results. Tim Tucker over at Biggerhammer comes to mind. I've shot his ammo as have some of my friends with great results.
Ammoman.com, Ammunitionstore.com, and Midsouthshooterssupply.com are a few places you can order ammo. Midsouth carries HSM ammo made with new commercial brass. I'm sure others will chime in with a list of their favorite vendors.
Reloading is good but plan on spending around $500 to get started. Midsouth has a kit for $400 but there is always something else to buy.
Avoid Yellow tip Dominican, Maine Cartridge Company, and TNW ammo. Those all have bad reputations but I've had no personal experiance with them.
Hope this helps a little and welcome to the club.
