Polycase Ammo

Anyone know much about it? I guess it spins.

    watched the video – two layers of drywall and 16″ of gel. so the goal is overpenetration?

    No personal experience, but Jeff Quinn has been testing it lately & says so far, he likes it.

  4. SPQR Says:

    American Rifleman has an article.

    So, are they going to make left and right-handed versions? IIRC, 1911’s use a left hand twist, and others use a right twist. I’m thinking a miss-match would cancel out any benefit to this design.

    Meets the definition of “restricted ammunition” in Virginia. That makes it a non-starter for me. I refuse to give some overzealous prosecutor a free felony charge if he doesn’t like something I do in self-defense.

    I’m beyond skeptical.

    The American Rifleman article/advertisement compares the action of the projectile to a boat propeller, first spinning in air, then lowered into water. The claim is that the bullet generates turbulence in ballistic gel that leaves permanent wound channels, just as the prop causes turbulence in the water.

    But: That boat’s prop is driven by a motor. That bullet is driven merely by its rotational inertia; and there’s not much of that, partly because the bullet has such a small mass, and partly because no bullet has much of its energy converted to spin — that spin is for stabilization only. A better analogy would be: Wind up that boat’s prop in air, then cut the engine, and while the prop is still spinning, lower it into the water. You’re not going to get a great rooster tail of water.

    If their claim is that the bullet’s rotation will be accelerated when it enters the target because the linear movement of the bullet will be converted into rotation from the fluid pressure on the “Power Blades” (TM) (i.e. simple angled flutes), then the author didn’t use a good analogy here. And that sort of spin isn’t going to cause turbulence in a fluid. No, sorry, that fluid isn’t going to somehow fly away from that bullet at speeds twice that of the projectile, as the article claims. The laws of thermodynamics just emailed me and said: Good luck with that, dude.

    There’s a whole lot of politically correct BS attached to this product (it’s lead-free, it’s recyclable (certainly one of my biggest concerns for a self-defense round — eye roll); it’s non-reloadable, so I guess those valuable casings can’t fall into the wrong hands.) Sounds fishy.

    I’m going to go ahead and call bullshit on this. A feather-light (74 grain in 9mm) non-expanding projectile moving 1450fps isn’t going to cause so much turbulence in a body, to damage organs through which it does not pass. Other than a liver shot (liver is very close to ballistic gel in consistency), it’s not going to leave any larger wound channel in any organ than would any other non-expanding 9mm round. This is marketing of snake oil, partly targeted at consumers and partly at government agencies concerned with “sustainability” and preventing people from re-loading ammo so that its distribution can be more tightly controlled.

    This ammo is certainly dangerous. Just not in the way it’s portrayed.

    Yeah, there have been at least a couple of articles on it in the dead tree gun mags. Basically, you have a chemical propellant ejecting a mass out a barrel into a target, so yeah; a total game changuh? No.

    “FORGET EVERYTHING YOU KNOW…!”

    I’ve actually used that phrase seriously, at times when I have to un-do someone’s misinterpretations as the starting point for helping them understand some basic mechanical problem.

    In this case? I think it’s mostly politically driven. A way of getting out in front of the lead ban movement. It makes some sense, I’m not opposed to it, but it ain’t no game changuh.

  9. Bob Owens Says:

    Fired 200 rounds of it Thursday. Low recoil made firing hammers very easy. Ballistics gel tests posted online look interested, as it spins for about 6″ before tumbling.

    Would like to see real-world “in meat” results.

  10. Pastafarian Says:

    Yep, I’d like to see that too — some real world testing. I was wondering if it would tumble — if those “power blades” in gel would act like an arrow’s fletching in air. Tumbling is great if the projectile’s moving at 3000fps. At pistol velocities…meh. I’m not sure that’s going to do much.

    I’d like to see how these things perform if they have to first punch through a hog’s sternum before having to make that wound channel. My bet: They become an unintentional frangible round.

    But if someone comes back and reports a bunch of cleanly dispatched hogs, using a pistol caliber round, I’ll take my skepticism down a notch. I have been wrong before.

Remember, I do this to entertain me, not you.
