...Are you insinuiating that these men had legal issues because the use of handloads?...
We don't know why each was convicted in connection with shooting his gun. We know that alcohol or drugs was involved, but we don't know that they were drunk. Do you?
And the point is that over a period 37 years only 12 claimed self defense shootings in Idaho involved handloads.

...But as said before, the forensics lab doesn't work for the prosecutor, it works for the court...
Actually, that's not correct. It doesn't work for the courts. Who it works for will probably vary State by State.
In California, in the larger counties the county Sheriff's Department runs the county crime lab to provide services within that county. Some police departments also run their own forensic laboratories. And there's a state crime lab for cities and counties which don't have their own. The state crime lab is run by the Attorney General's Office.

...If the conclusions drawn by the experts brought in by the prosecutor about the findings of the forensics lab are not to your liking, you'd be desiring to hire your own expert to challenge those conclusions, and I cannot see any reason to believe that your expert would not be allowed to testify about data provided by the court's forensic lab. Right?...
In general, if I have concerns about the government's forensic findings, much of the time my preference would be to have my experts do their own testing and come up with their own findings. Or, depending on circumstances, I'd use experts to impeach the government's findings. Or I could do both: have my experts do their own testing and generate their own findings; and help challenge the government's findings. Such challenges will often include disputes regarding methodology.
And if part of my strategy will be to challenge the government findings, a starting point will be whatever material I'm able to get from the government through the discovery process.

...If you are asking whether another forensic lab could be hired to study the same evidence that the state forensic lab had reviewed to try to produce another set of data for both sides' experts to opine on, well, honestly I don't know why the court wouldn't allow that,...
My experts will not be able to use the same material used by the government. But my experts will be able to use identical or substantially identical material, and if I can lay the proper foundation as I described previously, the court will have to let it into evidence.
Sam1911 said:
...if we're to the point of trying to have the ammo tested by a second agency, the court must have accepted that your handloads CAN be tested and the results submitted as evidence...
An interesting point. If the government has done it's testing with handloads, and that testing supports its case; and if I've done my testing with handloads, and it supports my case, we have a very interesting tactical situation. The government could decide not to use its test results, if the prosecutor has enough other evidence in his opinion to get a conviction.
The problem for the government here is that if it offers its (favorable to it) test results, it's then is going to have a hard time keeping my (favorable to the defendant) test results out. But if it's not offering its test results, it objects to mine because since handloads are involved, a sufficient nexus between the test and the event can't be established. That's likely to hurt me more than the government, because the government has to have a good deal more to talk about than just GSR tests in order to be going to trial.
I'm stymied. I can't object to the government not using its test results as evidence. That's not my business. And the government's position will be that it is not using those tests because the results are of questionable relevance because an adequate nexus between the tested ammunition and the event can't be established since handloads were involved.
True, I have the government's test results that I got on discovery. But I can't really use them for anything because they're adverse to the defendant.
This is why what happens in court is so very different from what happens in a lab.

...You may have a problem, but it is with the sufficiency of your testing agency, not with your handloads. The same argument would have to be made if you'd used a brand new box of Federals.
Not really. See above.

interested witness authenticating an exemplar used as the basis for expert testimony
So where's the prohibition against that? Is not the credibility of a witness something the jury determines?
Not when it comes to establishing a foundation for the introduction of expert opinion testimony based on scientific tests. Determining the adequacy of the foundation is the province of the judge.
