Ouch...........that's gonna put a stutter in your step my guess.
I am still gonna keep carrying a spare on my belt in a triple k pouch until a years up and see if it still shoots ok.
I am merely reporting my results they work.
Do they hit slightly different poa........do not and would not care its a in close piece.
If it hits 3" left of center mass at 25 feet or centers it the end results the same.
