    10mm 156 gr Lyman Devastator hand load fired from 4.5" barrel EAA Witness through four layers of denim into calibrated gelatin.

    BB: 587.3, 3.6"

    Impact velocity: 1,450 fps
    Penetration: 13.7"
    Retained weight: N/A
    Expansion: N/A

    This bullet definitely lived up to it's name. Like the Holy Hand Grenade of Antioch. I just couldn't stop taking pics of this one. The deepest recovered fragment only weighed 22.5 gr and measured 0.616" x 0.307" x 0.110" but that fragment plus all the strained fragments (45.6 gr) only adds up to 68.1 gr, leaving 87.9 gr unaccounted for. If you look closely, you can see the mark where a fragment left the block at around the 13" mark, just before the last fragment that is in the block. I believe this to be the core, which should weigh in the neighborhood of 87 gr. Hopefully I can test again to confirm this.

    10mm 200 gr cast softened point fired from 4.5" barrel EAA Witness through four layers of denim into calibrated gelatin. The bullet was water dropped and then the point was softened by hitting it with a propane torch while the base of the bullet remained in a water bath. 16-18 BHN. I apologize for the quality of the video. My main camera failed to record and I didn't notice I had the backup set to low quality. Let me know if you like the angle, though because I was thinking about including this angle along with my normal format. At higher quality, of course.

    BB: 588.7, 3.1"

    Impact velocity: 1,140 fps
    Penetration: 28.1"
    Retained weight: 203.1 gr
    No expansion

    10mm Double Tap 165 gr Golden Saber fired from 4.5" barrel EAA Witness into calibrated gelatin. I forgot the denim on this test. Sorry. Penetration with denim is typically slightly greater than without. The Golden Saber is not known for having trouble expanding after passing through heavy clothing and the additional velocity of the 10mm further encourages expansion.

    BB calibration: 598.5 fps, 3.0"

    Impact velocity: 1,298 fps
    Penetration: 13.7"
    Retained weight: 139.9 gr
    Max expansion: 0.783"
    Min Expansion: 0.517"

    One extra shot over the chronograph measured 1,286 fps.

    As reflected in the retained weight, there was substantial fragmentation and although the jacket and core were not detached from each other, the only thing holding them together was the gelatin itself. The jacket pulled away from the core as I removed them from the gelatin. The two fragments seen in the pic were recovered immediately next to the bullet so they were included in the retained weight figure.

    I added another shot that I haven't done on previous tests. It shows the split wound track, side by side, with the bullet in place at the end. This exaggerates the appearance of the wound but gives a better view of where the fragments were lost along the track. Let me know what you think so I know whether to include that shot in future videos.

    10mm 195 gr Mihec (shallow pin) over 80 gr 800X fired from 4.5" barrel EAA Witness into calibrated gelatin. I omitted the denim because this is intended as a woods load.

    BB calibration: 598.5 fps, 3.0"

    Impact velocity: 1,166 fps
    Penetration: 14.1"
    Retained weight: 196.8 gr
    Max expansion: 0.698"
    Min expansion: 0.657"

    Additional velocity numbers are:

    1,141 fps
    1,119 fps
    1,148 fps

    10mm 135 gr Myhec 10:1 lead/tin alloy over 12.5 gr SR 4756 fired from 4.25" barrel S&W 1076 through four layers of denim into calibrated gelatin.

    BB: 594.1 fps, 3.4"

    Gelatin results:

    Impact velocity: 1,548 fps
    Penetration: 7.1"
    Retained weight: 73.0 gr
    Min Expansion: 0.651"
    Max expansion: 0.708"

    We fired a few rounds over a chronograph with the same powder and alloy but different charge weights and these are the velocities we got:

    11.0 gr 1,512 fps
    11,5 gr 1,484 fps
    12.0 gr 1,568 fps
    12.5 gr 1,610 fps

    This is a short tribute to Andrew Wiggin

    I got a block of the Clear Ballistics gel...

    [​IMG]

    But I can't seem to find it! :eek:


    I wouldn't say it was HOT here in Louisiana, but the gelatin block evaporated before I could get a shot off! ???

    [​IMG]

    Last but not least, I was gel testing the Lyman cast Devastators Hollow Points....Boom!

    [​IMG]

    This was put together as a tribute to Andrew Wiggin's gelatin block testing, all the time and hard work involved in doing these test, that we all enjoy viewing and studying. It is a monumental task to prepare the gelatin, load up the equipment and drive out into the desert and set up the table, gel blocks, cameras, CHRONY and everything else, just to make a few shots.

    Thanks Andrew Wiggin 8)

    Thanks Andrew, more great shots. I like the TAC XP projectiles, although the cost is somewhat prohibitive.

    Yeah, I was worried about pushing them fast, but from the look of the primers, it seems fine. I've got a few of the 155 gr flavor left so I think I might see if I get them up to the high 1,300s.

    HAHA SHADOW!


    And Andrew .... those 175gr Flexlocs look GREAT! I have the 165gr variety loaded now in my G20..... will probably go to the 175gr eventually.

    Nice, controlled expansion, good penetration. Good stuff!

    Thanks!

    I agree that they look like a good choice for defense but they're far from full power 10mm.

    Do you know what alloy/hardness the Lyman Devastators used? Those factors can make a big difference in terminal performance. Thanks for all your great work!!

    I don't. But I think Shadow knows.

    What hardness lurks in the heart of bullets? The Shadow knows.
