    Gelatin tests

    I've been a member here for a while but just lurked. Then, for some reason I forgot about the forum until a thread was linked from one of the other forums I post in. I thought I'd share what I've been up to. If it's out of place or inappropriate, I apologize. Despite my join date, I'm still kind of new here so be gentle.


    First, a note: although I take every reasonable measure to assure the accuracy of my tests, there are a few substantial differences between my own and professional tests. The first is that my tests are not conducted in a laboratory environment; there are variables that are simply out of my control. The second is that I don't shoot a statistically relevant sample size. Sometimes bullets show a significant range in performance and I normally only do one shot per test. The third point is that the gelatin I use is Kroger brand food grade (250 +/-10 bloom), whereas professional labs typically use Vyse ordnance gelatin (250 +/-5 bloom). I also use non-standard size blocks. The size of the block shouldn't effect the penetration depth, expansion, or other factors, but it should be noted. That said, the tests are performed on actual gelatin (not synthetic "tissue simulant") that is as close to 39F as possible and I post the BB calibration results and my results are consistent with professional tests where the data is available.

    In short, my tests may not be as accurate as professional laboratory tests but they should be at least as accurate as anything you see in a gun rag (where they almost never publish their calibration results) and might be more accurate than tests performed using Simtest or Cleargel. They are just for fun but ought to be reasonably accurate. Here are a few of my more recent tests. If you'd like to see more, take a look at my channel. Please let me know if you have any questions or know of a way I could improve my test procedure. Thanks for looking.

    Nice videos! If you have any on Double Taps 150 grain loads I for one would very much like to seem them. Back when the 10mm first came out I was still in law enforcement, and carried one with the 175 Winchester Silvertip load. As of late, I have been entertaining the idea of picking up another 10mm. It really is a heck of a round with a lot of potential for many applications. Thanks!!

    Thank you.

    The 175 gr Silvertip tested well. I haven't tested the 150 gr load you mention but I'm not personally fond of Double Tap and wouldn't give them a red cent. They are dishonest about velocity and that Equalizer load is simultaneously a ridiculous gimmick and seems not to perform anything like the way they claim.

    If you're interested in getting back into 10mm, consider Underwood and Georgia Arms. Hornady's 175 gr Critical Duty is also good to go, though not quite up to the power level that a lot of folks expect from 10mm. I've done a lot of 10mm testing so check out my page. Also take a look at tnoutdoors9's page if you haven't already.

    I've done (and still do) a lot of business with Georgia Arms, so I will check out their offerings as well. Thanks for letting me know about your testing of the 10mm, I will stop in and look at your tests. Thanks!

    Gelatin tests? No answer for the real world IMO.
    So you want a holy war? How many holes would you like?

    If you'd bother to do a little research you see that gel tests and real world shootings correlate very closely. Now shot placement is a whole different thing, a bullet can act exactly the same as it does in gel when hitting a bad guy, penetrate deep enough and expand,but if the shop placement is not in the vitals then it won't stop a bad guy but that doesn't mean that gel does not represent a good test medium.

    agalindo nailed it.


    "The IWBA published some of Gene Wolberg’s material from his study of San Diego PD officer involved
    shootings that compared bullet performance in calibrated 10% ordnance gelatin with the autopsy
    results using the same ammunition. When I last spoke with Mr. Wolberg in May of 2000, he had
    collected data on nearly 150 OIS incidents which showed the majority of the 9mm 147 gr bullets
    fired by officers had penetrated 13 to 15 inches and expanded between 0.60 to 0.62 inches in both
    human tissue and 10% ordnance gelatin. Several other agencies with strong, scientifically based
    ammunition terminal performance testing programs have conducted similar reviews of their shooting
    incidents with much the same results--there is an extremely strong correlation between properly
    conducted and interpreted 10% ordnance gelatin laboratory studies and the physiological effects of
    projectiles in actual shooting incidents." - Dr. Roberts



    "The test of the wound profiles validity is how accurately they portray the projectile-tissue
    interaction observed in shots that penetrate the human body. Since most shots in the human body
    traverse various tissues, we would expect the wound profiles to vary somewhat, depending on the
    tissues traversed. However, the only radical departure has been found to occur when the
    projectile strikes bone: this predictably deforms the bullet more than soft tissue, reducing its
    overall penetration depth, and sometimes altering the angle of the projectile's course. Shots
    traversing only soft tissues in humans have shown damage patterns of remarkably close
    approximation to the wound profiles.

    The bullet penetration depth comparison, as well as the similarity in bullet deformation and yaw
    patterns, between human soft tissue and 10% ordnance gelatin have proven to be consistent and
    reliable. Every time there appeared to be an inconsistency a good reason was found and when the
    exact circumstances were matched, the results matched. The cases reported here comprise but a
    small fraction of the documented comparisons which have established 10% ordnance gelatin as a
    valid tissue simulant." - Dr. Fackler

    He sure did. Those who dismiss testing in ordnance gelatin out of hand often do so because they misunderstand why it is used.
