AFTE Store - Hornady Knurled Bullets: Their Class Characteristics and Properties of Forensic Interest

The Hornady Manufacturing Company of Grand Island, Nebraska produces a number of lead pistol bullets with a unique knurled bearing surface. Under the microscope, this knurling takes the form of evenly spaced, diamond shaped indentations arranged in staggered rows. This pattern will typically survive after dischargeand impact and may serve as a means of class characteristic comparison. A particulate coating on these bullets also provides a source of some unusual trace evidence.
