## Step1Question 12 is about the effects of rifling on a bullet. Rifling refers to the spiral grooves cut into the bore of a firearm barrel. These grooves cause the bullet to spin as it travels through the barrel, which improves its accuracy and stability. The direction of the twist (right or left) depends on the design of the rifling. Therefore, the statement that rifling can cause a bullet to have a right or left twist is true.## Step2Question 13 is about the individual characteristics of a cartridge casing. Cartridge casings can have unique markings that are left on them during the firing process. These markings can include firing pin impressions, bolt or breech face markings, ejector markings, and extractor markings. These markings are unique to each firearm and can be used to identify the specific firearm from which the cartridge was fired. Therefore, the statement that individual characteristics of a cartridge casing include firing pin impressions, bolt or breech face markings, ejector markings, and extractor markings is true.
