Firearms PRE-LAB QUESTIONS 1. What are the winding grooves which help a bullet maintain a stable trajectory called? a. rifling 2. Would you expect to find more gunshot residue around an entrance or exit hole? Explain your reasoning. a. I would expect there to be more gunshot residue around the entrance rather than the exit hole because it first has to enter then it would lose residue as it passes through an object. 3. Would a hand gun or shot gun be more difficult to trace and determine class characteristics? Explain your answer. a. A shotgun would be more difficult to trace because there are no consistent markings or rifling that are the same on all of the guns. © eScience Labs, 2016
