Anyone know where you can get good NATO HEADSTAMP BRASS for reloading? Searches have been coming up empty on brass with NATO headstamp in .223 and 7.62. The ones that have come up usually are mixed manufacturers. I have seen XM855 SS109 green-tip 5.56 ammo in some auctions. I would be looking for the brass used in the manufacture of this ammo or this type in once fired. Can you even buy NATO headstamp brass new unfired? Also would like to know about the loose ammo. Is there a reason this ammo was not ever packaged like not passing some sort of inspection,off spec, blemishes, flaws, seconds, etc.)or something of this nature. If someone has some brass like this would you care to weigh some so I could compare it to the weight of the LC brass I have from the Federal XM193 rounds i've shot?
