    Hornady 223 Rem 75gr BTHP TAP Gel Test Results





    Just finished up testing the Hornady 223 75gr BTHP round (#80265) from my 1 in 7 Palmetto State Armory 14.7'' CHF 1 in 7 twist barrel. The test was shot at 15 ft, 60 degrees, and 300 ft of elevation and the Clear Ballistics FBI spec gel block was used with 4 layers of denim.

    Results:

    -2386fps, 948 ft/lbs energy
    -Expansion/fragmentation started at the 4''
    -Jacket separation occurred at 10''
    -Deepest penetration point was 19''

    The manufacture of the gel block, Clear Ballistics, claims their gel meets FBI specs for testing. I calibrate my gel per their specs prior to testing and use 4 layers of denim per IWBA protocol.

    However, by no means am I saying this test is a substitute for the great work industry professionals like Dr. Roberts and others do. I'm just a shooter that likes to learn about the products I use.



    Here's the video of the test:

    would it be possible to redue the test with a 16" and 20" barrel for comparrison on velosity and fragmentaion. would love to see that. dont know where you are located, but if close enough I would even donate my rifles for the test.

    Thanks for posting that... I've only shot 3 boxes of this ammo and was impressed enough with the accuracy and reliability that I keep two 30 rnd pmags loaded as spares nearby for home-defense situations and a 20 rnd Lancer AWM with Winchester Supreme 55gr ballistic silvertips in the gun. 2386fps seems slooowwww though... I was expecting a little more...

    WOW, no joke just woke up this morning wondering how these bullets do, and came across your video, now its up here

    Are the "Match, or Super performance" bullets of the same construction?

    the overall penetration is much deeper than I've seen in most other tests to include Hornady testing...

    Likely due to the low velocity and lack of fragmentation normally associated with this bullet.

    I have both length ARs. I may get around to it one of these days but it just takes time and I have a lot of other ammo I'd like to get to before I start re-testing ammo with different variables. Recycling the gel is a b**ch...

    That was my thought as well.

    Nice test.

    The 4" neck length or initial penetration may not be ideal.

    Hornady's own testing shows a 1" neck in bare gel and a wider cavity.

    They have all the other cases except 4LD.

    There may be a gel calibration issue, as I don't expect the 4LD to affect a rifle round significantly.
