Dr. Andy Anderson, Chuck Haggard, Shane Kerwin, and Matt Landfair discuss the Tactical Anatomy Summit, three-dimensional anatomy, defensive marksmanship, trauma medicine, and the realities of stopping violent threats.
Understanding Bird Shot Is Not For Defense
Comparing the FBI ballistic standards and the idea of birdshot being an effective defensive tool shows the profound ignorance of people pushing for the birdshot. The FBI standards establish reliable penetration of 12-18″ in verified ballistic gel from reasonable ranges beyond contact distance. Birdshot can (can- not will) create lethality at contact distance, but diminishes … Read more
P&S ModCast 308 — Pistol Bullet Performance
Dr. Andrew D. Fisher, Mark Fricke, Chuck Haggard, Dr. Sherman House, and Matt Landfair discuss pistol-bullet wounding and performance.
Duty Caliber Pistol Performance
When I was young and eager to learn everything gun related, I had believed defensive pistol ammo had to be some form of hollow point to be effective. The more I learned what duty and sub pistol calibers did, the more I understood how other options fit the defensive paradigm. Let’s first establish what we … Read more
A Simple Explaination of Duty Pistol Caliber Terminal Ballistics
Optimal pistol wounding is caused by a balance of projectile weight, construction, size, materials, shape, and velocity (not even talking about shot placement here). Too much or too little of any variable and the projectile performs poorly. Performs poorly- being compared to HST or Gold Dot which are the current standards of optimal performance within … Read more
