The x-rays unequivocally show that LM projectiles do in fact lose their integrity and produce multiple permanent wound tracks in living tissue. Here we now have small arms ammunitions that will “bust” 3A armor, penetrate hard barriers, but at the same time not slice through tissue and threaten the community we are sworn to protect. The duty ammunition carried by armed professionals, be they law enforcement or military is based in large part on bullet comparison tests in a universally accepted test media. Although American ballisticians claim that 10-percent Kind and Knox ballistic gelatin simulates living tissue, none of the homogeneous test media currently in use accurately replicates living human tissue, because the latter is not consistent in its composition. Bone, cartilage, connective tissue and organs of varying densities will react differently to invasive, high velocity projectiles and produce different results in bullet penetration and deformation. The best that we can hope for in gelatin, wet newspapers, clay, soap, water or “Perma Gel” is to compare one bullet with another’s performance in that media. New Test Media Perma Gel (PG) resembles gelatin, but does not meet the FBI’s criteria of 2.95"3.74" of .177 caliber pellet penetration at 600 fps into 10-percent Kind and Knox 250A-gelatin. Gelatin must be shot within 20 minutes of being removed from a refrigerator where it had been stored at 39.2 degrees Fahrenheit, so it is shot cold. Conversely, living tissue is warm to hot. PG’s main advantage is that it does not have to remain refrigerated prior to use and does not deteriorate at temperatures above 75 degrees. It will take multiple hits without affecting bullet comparisons and can be reconstituted by heating it to 225 degrees F. Criticisms & Condemnation One of the major criticisms directed at LM ammunition is not penetration in depth in 10-percent ballistic gelatin, but that it does not deploy (expand) or fragment in that media. It has also been consistently observed that at systemic temperatures below that off the human body or living animals the round punches through like full metal jacket projectiles. This “failure” to perform in the standard, bloodless methods (10-percent gelatin in USA and 20-percent gelatin in Europe) currently relied upon to measure terminal ballistic performance have caused a few respected ballisticians to heatedly reject this ammunition — and virtually call LM’s principles charlatans. New Paradigm A digital X-Ray machine was used to take pictures of bullets fragments. Here it’s used on a thoracic shot. 48 However, LM principles claim their ammunition’s performance represents a “New paradigm in ballistic performance WWW.AMERICANCOPMAGAZINE.COM • JULY/AUGUST 2009
