Good grief.... obviously the bullet stuck in the lands and that is why it separated upon extraction.... the powder jammed up the works.... jeesh , not rocket science
that's exactly right that's what I hinted to on my first posted. it's just figuring out if the ammo Chambers off or the ammo was off somewhere... if every round chamber had been fired before extracted you wouldn't know. that's the first round that have been extracted not fired it's up in the air..
