Well, it sure isn't Malaysian surplus ball. This is the worst stuff I've ever seen in .223. My AUG detests it, and two HK93s repeatedly misfired with it. If an HK won't shoot it, something is badly wrong.
Hirtenberg SS109 (or whatever the Austrians call it...) shoots very well. Too bad it cost so much. It was good stuff. South African military ball was also pretty good.
Generally, though, I like .223 handloads best of all. .223 is so cheap to reload it isn't even funny. Vast amounts of components can be had for a pittance. Then it's only a matter of time to slap everything together. Best of all, my standard .223 load outshoots any military ball I've bought. The only stuff that shot better was Federal Blitz.
