223/5.56mm rounds consistently performed better when it comes to reduced over-penetration.

It does however show the obvious fact that the. Now, this test can also be defined as anecdotal because it does not and cannot replicate every home in America. 223 has a maximum penetration of 8 walls (fired from an M16, M4A1 and a H&K G36) the 62 grain bonded 5.56 (fired from the same weapons) had a maximum penetration of 8 walls. 40 S&W consistently penetrated all 9 walls. When bullets started flying, the 147 Grain 9mm consistently penetrated all 9 walls. The test was designed to replicate an average home. Wall 9 was constructed of 1 ВЅвЂќ drywall, 1 sheet of 7/16 inch plywood, 3вЂќ of soft insulation, 9/16вЂќ hard insulation and 1/16 hard plastic siding. Walls 1-8 were constructed of 2 ВЅвЂќ sheets of drywall. Nine walls were constructed and spaced 4 yards apart. While tests with bare gel were not particularly telling, the same rounds were then tested against barriers. 40 S&W, the average was 15.25вЂќ with an extreme of 19.вЂќ 223 55 grain was 11вЂќ with an extreme of 13.5.вЂќ The 5.56 62 grainвЂ™s average was 16вЂќ with an extreme of 17.вЂќ The 9mm 147 grainвЂ™s average penetration was 12.5вЂќ with an extreme of 15.5.вЂќ And for the. Bare ballistic gel tests found that the average penetration of the. These rounds were tested against a 147 grain 9mm hollow point and a 165 grain. The 5.56mm round performs exceedingly well in this area (meaning it is not as likely to over penetrate), making it perhaps the best choice for home defense where over penetration is a concern (as it always should be).ДЄs evidence of this I offer data collected from the FBIs Weapon Selection Test, the San Diego SheriffвЂ™s Department Structural Penetration Testing and the DEA's Constructed Materials Test. a human target, the largest concern with a self-defense round is the over-penetration of intermediate barriers like doors walls, appliances and furniture. You should expect over-penetration, even if it does not occur (remember backdrop). I say expected because no reliable round that will always remain in the body while providing desired incapacitation has yet been developed. This is due to the round's velocity and the relative density of the target compared to the bullet. Over-penetration of the human target can and should be with expected with any round. While testing can (and is) performed on ballistic gel and intermediate barriers in controlled settings, there is virtually no opportunity to test these rounds under scientific controls in the real world. For the layman, the difficulty involves nature of the target and the environment. Body size, health, clothing worn, heart rate, stimulants, mental condition, barriers, mindset, all of these and more make it impossible to predict a rounds effectiveness based strictly on its caliber, grain, development technology and velocity.ДЄnother larger and ever-present myth with the 5.56mm round is that of over-penetration. The reality is, there are simply too many factors involved in the shooting of a live threat to produce total-package reliable data. Handpicked favorable results are often used while unfavorable ones are discarded. Now, about all the вЂњdataвЂќ on this round or that round: incapacitation field results and lab testing are nothing more than a collection of individual results factored into a percentage. Psychological incapacitation is common but cannot be predicted. People fall when they are shot because of fatal damage to the CNS, extreme blood loss (which takes time), psychological factors (because they realize they were shot and either go into shock or believe they should fall down) or damage to load bearing bones. Barring the introduction of a 30 x 173mm HEI round directly to the thoracic cavity or medulla oblongata, there are very few guarantees of a вЂњone shot stop, all the time, every time.вЂќ Nor does the impact of a bullet itself make a person drop. We hope you'll engage in discussion, but hope even more you'll do so by addressing the contents of the op-ed.ДЄnyway, we left off with the statement that There is no magic bullet. Unfortunately only a few of those commenting bothered to read the article. Part 1 engendered a lot of discussion yesterday, especially on social media.
