A lot of this ammo is showing up at most distributors at close to $0.41 per round delivered in metal ammo cans. It has been a long time since it was this cheap. Brass and berdan primed.

For my accuracy test ammo I been using the South African surplus 308 ball ammo. It's good enough to see how accurate a new gun is. I'm getting 1 1/2" groups with most military surplus and new rifles in 308 at 100yds. With no scope. My point is once I'm sure of the accuracy then I can tell if another brand of ammo is good or not.
As am I. It's been awhile but years ago I shot some of it up in a CETME rifle (one of the early "good" ones) and was not impressed. Burned very dirty, a few dud primers, etc. maybe a bad lot but I wasn't enthralled.
Speaking of dirty, I did a ftf a couple of months ago with local guy for a SA M1A that was bought by him brand new and unshot by him. Tags still attached to trigger guard. The bore was filthy from the factory with no effort to even swab it before boxing it up.
5% failure rate through 400 rounds for me. Some required 2-3 strikes to go bang. Retail ammo runs fine through my rifle so I don't think it's an issue with my rifle.
