Which of the following statements is true?

Question

Quizplus · Accepted Answer

The comparison microscope is an essential tool for firearm examiners to compare markings left on fired bullets and cartridge cases to those made by a specific firearm. The other statements are incorrect or incomplete. The gauge of a firearm refers to the number of lead balls of the same diameter as the bore that would weigh one pound, and it is not necessarily equivalent to the diameter of the bore. Carbonaceous smoke or soot around a bullet hole can indicate the distance of a shot, but the range for this is highly variable and depends on factors like the type of gunpowder and environmental conditions. While the number and twist of lands and grooves on a bullet can provide some information about the type of firearm used, they are not sufficient for individualization without additional forensic analysis.
