Decent plinkin' ammo, not bad at all, sealed air and watertight, relatively cheap-what else could you ask for?
300 for around $37-40.

For those looking at surplus outside of the US, be aware that the British surplus stuff is generally underloaded, there are some problems with the Greek Olympic brands, and S&B (it's not surplus, I know), has caused KB's in several AR's.
