Hell... who the hell knows... ?
There is still no conclusion as to what the problem actually is, or was, or if there actually is a problem with the pistol or the ammo, or both, or neither or not...it's still just all guesswork.
Springfield says it's good to go...you still have your doubts...so...
Don't shoot it...!
Don't shoot the Hornady ammo...!
Plunk it with a different brand of ammo. Any cheap ammo is fine. See if it looks any different...then post some pictures...then...
Don't shoot it...!
Then take it to a local gunsmith who knows what he's doing for a safety inspection and a headspace check and test firing.
Tell us what he says.
