"A plethora of 5.56mm/223 Remington loads utilizing expanding barrier-blind projectiles have come to the market in the last several years. One of the top performing loads in this category that is currently issued by the FBI is the Winchester Ranger 5.56mm 64 grain RA556B. Terminal ballistic testing conducted by the esteemed Dr. G.K. Roberts has shown that this load has an average penetration depth of 17.1â in bare 10% ordnance gelatin with a recovered diameter of 0.46â (when fired from a 16" barrel.) After passing through an intermediate barrier of automobile safety glass, the load has an average penetration depth of 13.6â with a recovered diameter of 0.35â (again from a 16â barrel.)"
