Could have been in an ar chassis.. hit feed ramp/barrel extension lug and jammed, distorted and did not feed correctly, then a forward assist was "whacked" to try to feed/chamber to no avail
^^^^This has my vote.Looks like someone forgot to switch from their sizing die to the seating die and jammed the bullet up in between the decaping rod/expander ball and the inside of the die when they went to seat the bullet.
I think it might be a bullet stuck in the throat and he ran a rod down the muzzle to knock it out.
