Taliv,
Were the projectiles from Wideners? I had good results with the 168s from them. I only get to 600yds though. At one time they stated they were Prvi but haven't see them name the mfg lately. They also don't give the BC. I just shoot them without knowing the BC. I haven't even tired to see if Wideners can provide the BC. They also taper alot more than others like Nosler, Sierra & Hornady which have a more pronounced straight section.
Yes, I know the 168s aren't the best choice for .308s. At some point I may move up the ammo food chain and switch to 175s with a pedigree.
