It matters not that your gun is perfectly legal at 11.5 with the 8.4 grain pellet, the problem is the word potential.
It would be like giving every car driver a speeding ticket as all cars have the potential to exceed the speed limit!
The thing is with driving offences you have to have proof, so Camera traps and policemen playing Dirty Harry with lasers abound. They have to show you were exceeding the speed limit at the time!
It matters not of your seized gun was only firing the 8.4 grain and was therefore at a legal power level, the problem is that with a 10.3 grain it is at an illegal level and therefore you are a criminal! If it is tested with a 10.3 grain and over you are criminal despite never having committed an illegal act!
