Ok guys i am a little stumped as to what happened at the range with one of my rounds (american eagle .223 out of an M&P15 PSX)
When i fired the round the bullet went downrange but it just felt wrong, i almost thought it was a squib cause the action didn't cycle.
- The case didn't extract probably because the bolt didn't unlock all the way. - The primer had come out of the pocket and bound up the between the lugs somehow (the cup was torn apart quite badly, almost to the point of looking like it unrolled.) It was quite hard to get the bolt to unlock all the way.
- The primer was NOT pierced.
- When the bolt unlocked however, the case remained in the chamber.
- I can see on the case bottom that the details of my bolt face has been "stamped" into it. (extractor etc...)
- Plenty of black in the primer pocket.
So, i *think* it was a slightly overcharged round. If you guys can give me any more insight based on that info please do as i'm not that experienced in the AR platform.
I cant see any visible damage to the bolt or any of the other surfaces, but
i'm gonna take the rifle to a smith on Tuesday along with giving American Eagle/Federal a call.
Thanks in advance guys.
Extra info as requested:
- Never shot any steel ammo throgh this
- Weapon cleaned after every range trip
- Less that 100 rnds fired before the problem (same ammo)
- Rife still operates flawlessly, not adverse effects
- No bulging or distortion of the bore
-EDIT, PICS ADDED-
The top pic clearly shows the imprinting of my bolt to the case
