Could have just as easily been a bad factory round. During the last ammo shortage (obammy era) there were lots of [various forums] posts about bad ammo- over and undercharged, commercial ammo.
I've had 4 bad factory rounds in my life (that I can specifically recall) and in 2 of the instances, Remington bought the entire case of ammo back.
(I'm just being defensive since I haven't had my coffee yet and I'm a reloader)
