I find the accuracy of Barnaul .223 ammo to be "service grade" at best. On the old IMAS forum a member miked some Barnaul projectiles and they came out at a true .223, rather than .224. Other than that I find it to be pretty reliable ammo. Goes bang every time and doesn't cause stoppages. You can get the projectiles pretty cheap actually, $38 for 200, $160 for 1000. That FNB ammo was a good score, useless to me though as both my AR uppers are fast twist.
