Has anyone shot any of the M118 Sniper Ammo 7.62mm NATO in their 308 NDM-86? I've mostly only shot Black Hills 168 grain, as when I first picked up my rifle, this was suppossedly the most accurate at that time (3 yrs ago). Saw some of this for sale, and was curious if anyone has shot any of it? If you have what did you think of it?
