sighting in on: Liberty Ammunition
T ere are those who believe in only one or the other and some who believe in both. Neither of these matter much if you shoot someone in the calf. Cartridges for police duty use are often focused on penetration since we’re around vehicles so much during the course of performing our jobs. Self defense, off -duty cartridges are often more focused on initial tissue and organ damage without as much concern for penetration.
FBI Protocol T e Federal Bureau of Investigation’s Pene- tration Test protocol for handgun cartridges consists of fi ring bullets into bare gelatin and through clothing, steel (car door type), wall- board (drywall), plywood, and automobile glass. T ese are the standard tests conducted by the agency and by ammunition manufac- turers under scientifi c conditions. At a Las Vegas SHOT Show range event, I reached out to Liberty’s representative to inquire about T e Police Marksman con- ducting a test of Liberty’s Civil Defense
Test fi ring the 9mm 50-grain Civil Defense round into bare ballistic gelatin.
A local offi cer inspects the gel block after witnessing several different rounds for comparison.
49 The Police Marksman Summer 2015
A common, police-oriented 147-grain lead 9mm bullet (bottom) penetrated 14 ½ inches but did not create a dramatic wound channel. Another 135-grain lead 9mm also oriented for police use penetrated out the back of the entire 16-inch gel block and was recovered in the berm. Its wound channel was not as impressive as the Liberty 9mm’s.
