Over the years I have bought very little factory ammo, so my experience with it is limited. One thing I have found out is that nothing is certain, you have to shoot it and see what happens. I agree that FMJ bulk bullets very rarely shoot well. Another thing about factory ammo is that if you find some that shoots well, a different lot # may not shoot as well.
Just for the record, I seldom find factory ammo that shoots as well as my handloads. Even stuff like Blackhills match, Federal Gold Metal match and Lack City match. The only thing that I can't consistently beat is Weatherby ammo loaded by Norma. Hurts my feelings it does!
