Double Barrel 1911 Ballistics Test

Jerry Miculek tests out different ammo in the Arsenal Double Barrel Pistol. He loads one magazine with Hornady 220gr +P flex tip hollow point and the other magazine with regular 230 gr ball ammo. The most surprising aspect was the ball round flying through the large cavitation made by the hollow point. Because the hollow point was moving faster through the air, it hit the ballistics gelatin first. The hollow point opened up as designed and started to slow down and create a large wound channel. While the gelatin was expanding from the hollow point, the 230gr ball round caught up to with the hollow point and was traveling in the cavity made by the hollow point.

In this screen shot, you can see the two projectiles.

    If I heard right, there might be footage somewhere of Jerry Miculek shooting Chicago style.

    While I understand why they use ballistics gel–as a paramedic with 30 years of treating GSWs I can tell you this is not the way they behave when shot into an animal, esp. a human being. Even if there was that length of soft tissue to be 'shot through', it would influenced by a large number of other things, particularly resistance and connective tissue (starting with the skin) of various densities. You're shooting into a sack of meat, with bones and differing densities. Not at all what you're shooting at when you shoot ballistics gel.

    Primary cavities are what kill people. Secondary cavities are impressive when you shoot ballistics gel with a high speed camera. Look at the block on the normal camera. The primary cavity is about what you'd expect-about .45 inch for a .45ACP round. In this case, it doesn't sound like the Hornady round could have even penetrated the block in the second example. The ball ammunition barely penetrated in the first example. Add a couple of layers of denim over that and you aren't going to get even that much penetration, with a correspondingly small primary cavity.

    These demonstrations are 'trick shooting' and have absolutely nothing to do with real life-IRL, I've seen an individual shot six times with a cal. .357 revolver who just kept coming. He wasn't hit anywhere vital. The fact he was intoxicated on phencyclidine increased his pain tolerance, but didn't change the fact he wasn't exsanguinating very fast. He didn't even die, directly, from the GSW–he died in the hospital, 12 hours later, from aspiration pneumonitis after inhaling blood and his own vomitus, as well as other complications.

      @Wyatt Earp You should probably look at some 45 ACP FMJ ballistics tests before you say it wouldn't go through that block.
