Creedmoor hates Federal ammo

Not a great day shooting and it wasn't me. Windy but not gail force (hidden excuse 1) that would explain the opening up of groups. Nope, I say it was the Fed ammo. Mine likes the Hornaday 140 back box. It's not a fan of the remington 140 either but it was better than this fed crap (excuse number 2).
Good behind the gun and everything I was doing felt good. Good day anyway but dissapointed in the results.
