The court held that the expert's opinion that the bullets were fired from the same gun was "properly predicated" due to another Alambama case that held it was "proper for a jury to compare an 'evidence shell' with two 'test shells' fired from the evidence gun." Further, the court notes that this test could not have been done in court, and that the expert demonstrated his "path of research" through showing exhibits with large photographs of the evidence shell and the test shell.
