Forensic Ballistics: Firearms, Evidence, and Integrity

A comprehensive mixed mock drawing 5 questions from each of the two easy Forensic Ballistics mocks, 10 from the medium mock, and 10 from the hard mock — giving a full cross-level challenge across definitions, applied casework, and professional integrity.

The 5 questions from Easy Mock 1 (Foundations) cover: rifling definition, firing pin impression, internal ballistics, shot pattern for range estimation, and cartridge case extraction and ejection.

The 5 questions from Easy Mock 2 (Firearm Types) cover: double-action revolver mechanism, shotgun choke, ricocheted bullet features, Hague Convention and FMJ ammunition, and revolver cylinder rotation mechanism.

The 10 medium questions cover: class characteristic exclusion from twist direction mismatch, range estimation from soot without stippling, fragmented bullet examination, shot pattern interpolation for range estimation, cartridge case value without a bullet, high-velocity vs low-velocity wound ballistics, serial number restoration by acid etching, skull external bevelling as exit indicator, IBIS crime-to-crime link workflow, and reporting class characteristics matching multiple models.

The 10 hard questions cover: institutional bias when examiner's colleague is suspect, GSR on occupationally exposed firearms officer, AFTE Theory with unexplained differences in 2 of 6 LEAs, re-examination with new 3D imaging technology, ejection pattern and shooter handedness challenge, contextual bias from pre-examination photograph, old ammunition headstamp discrepancy, smooth-bore katta forensic linkage possibilities, barrel wear after five years of continued use, and post-conviction exhibit mix-up voiding identification.

Allow 15 minutes. Suitable for students who have completed all four individual mocks and want a cross-level revision challenge.
