It's deformed (crushed due to shear force) as opposed to expanded. The bullet on the right is expanded, where the core of the bullet nose "flows" backward around the shank (due to inertial force).

The bullet on the left didn't expand, it deformed. Yes, its recovered diameter is larger than its unfired diameter but this is the result of colliding with a solid medium, like the front end of a car deforms when it runs into a brick wall. Hitting bone also causes deformation instead of...

The cops in the video are pursing a violent criminal with the intent to seize him, either by arresting him or killing him. Private citizens don't do this. In the overwhelming majority of situations, bad guys run away from defensive gunfire (just like the guys in the videos are doing). The...

ACLDN isn't insurance nor a company. ACLDN is a cooperative.

I carried a Beretta 96FS (.40 Cal) on patrol. It fit my hand nicely and I shot very well with it. There were two things I didn't like about it: The slide mounted hammer drop safety. I much prefer the Taurus PT92 frame mounted safety/decocker. The machined front sight. A dovedtailed front...

How do I know? I'm a pistol instructor and, to stay on top of things, I keep my finger on the pulse of current trends. Rapidly unfolding events combined with the extreme stress of possibly being murdered often causes the unexpected to happen in a time compressed situation, despite training...

It depends. A double action revolver usually has a longer and heavier trigger pull than an auto pistol, and can it be difficult for some people to operate. Whereas, the slide of an auto pistol can be a problem for some people to retract. However, this can be solved by using the "push/pull"...

Don't buy Underwood "blemished" ammo because the blemish can be inconsistent bullet seating depths. I know. I made that mistake. Once.

Bodycam videos have revealed that many cops have "shootable" problems with full-size duty pistols, usually caused by poor grip due to the haste of drawing to engage a sudden spontaneous threat. Magazines fall out and stoppages happen at a much greater rate of incidence than what happens on the...

As best as I can determine, with a quick Google search, Jeff Cooper established "The four rules of firearms safety" in the mid-1950's.

Sometimes your eyes will "see" what you're expecting to see. Never check to see that a gun is "unloaded". When checking the chamber or cylinder, consciously ask yourself, "Is this gun loaded, yes or no?" That slight change in mindset slows you down and makes the act of checking the chamber a...

Bullets and knives cause bleeding, therefore focus your equipment to stop life-threatening bleeding. - Tourniquet for limbs. - Hemostatic gauze for packing wounds at junctions where limbs and torso meet. - Chest seal. Keep this stuff separated from other first aid stuff so you don't have to...

TSA is NOT looking for common gun powder residue. They're looking for trace high explosives, like PETN, that a bad actor mistakenly believes will somehow be masked by common gun powder.

I zero a handgun RDO at 10 yards, allowing me to make head shots to 25 yards, and torso shots to 100 yards. For rifles, determine the max point blank range of the cartridge you're shooting and zero your optic to that.

The abstract (summary) describes internal blunt trauma injury and calls it "hydrostatic shock". The injury is identical to being kicked in the abdomen and the blunt trauma injuring the liver. Find us a medically accepted definition of "hydrostatic shock".

Hydrostatic shock isn't a wounding mechanism. It's a layman's term without definition as to what it allegedly is and what it allegedly does. Wounding mechanisms are: Penetration Yaw Fragmentation Permanent cavity Temporary cavity

What people believe is "hydrostatic shock" is the temporary cavity.

The best .380 loads use Hornady's XTP bullet. Standard pressure or +P, it really doesn't make a difference with XTP.

FMJ bullets yaw 180 degrees in flesh, because traveling backwards in soft tissues is their stable state. This is because the bullet's center of gravity is closer to the bullet's base than tip. Steel core Russian 7.62x39 FMJ penetrates deeper (10-12 inches) before it yaws than Yugo lead core...

I wasn't as lucky. I needed a small knife blade or small screwdriver to pry them out.
