Summary of reasons for ruling
Defendant argued that the expert should not have been permitted to state his conclusions because he did not present a microphotgraph of the exhibit shell and the test shell for the jury to examine. It looks like the court relies on a Montana case that "'Evidence of experiments made out of court and not in the presence of the jury are admissible upon the same principle as the experiments which are conducted in the jury's presence."
