here is an exerpt FROM Massad Ayoob himself citing a case law along with providing the name of the lawyer associated with the case law he is citing. Before I provide the excerpt let me clarify that this is not regarding a modified handgun but reloaded ammo...so YES Massad Ayoob himself provided the following...this is in his own words:

...What no one has mentioned yet in the discussion is the complete ABSENCE of cases where a court has accepted a handloader's word or written record for what load was in the gun at the time of the shooting. I've been having this same tired discussion on forums for something like half a decade now, and no one has yet found a case where it was accepted. Why is it so important? Because self-defense shootings often occur at "powder burning distance," and gunshot residue patterns on the opponent's clothing or body can confirm your account of the incident. In the case some have mentioned here (NJ v. Daniel Bias) the court refused to accept evidence of a light load that would not deposit GSR at a certain short range. Nor would the court allow the remaining rounds in the gun to be analyzed, since the prosecution effectively argued that the handloader might have had a different load in the "fatal" chamber than the remaining ones.

For the party requesting a case citation, it would be State of New Jersey versus Daniel Bias. Last I knew the trial transcripts were archived at The Superior Court of Newersey/Warren County/313 Second Street/PO Box 900/Belvedere, NJ 07823. Those who wish to follow the appellate track of this case willf ind it in the Atlantic Reporter. 142 N.J. 572, 667 A.2d 190 (Table). Supreme Court of New Jersey State v. Daniel N. Bias NOS. C-188 SEPT. TERM 1995, 40,813 Oct 03, 1995 State V. Bias 142 N>J> 572, 667 A.2d190 (Table)

For the party who wanted to hear about it from "a real, live lawyer," they are free to contact Attorney John Lanza and Attorney Elisabeth Smith. Both of these "real, live (and very skilled) lawyers" defended him in his multiple trials. Both told me that if the gun had been loaded with factory ammunition, they were convinced the case never would have come to trial. (Began as a murder charge, ended with a manslaughter conviction and a bankrupt defendant.)
