Hornady 223 Rem 75gr BTHP TAP Gel Test Results

Thanks for the video! I've been eyeballing this ammo as well and your video pretty much covers all I wanted to know. Subscribed.

From a terminal effects standpoint for HD/SD, I like the ~60gr bonded projectiles better than the 75-77 grain match.

Below 2400 fps is pretty bad especially since it looks pretty warm where you're at. Better off buying the Black Hills load using the Hornady 75gr as this load doesnt seem to be using the T2 version of 75gr bullet.

The test was shot at 15 ft, 60 degrees, and 300 ft of elevation

Indeed.

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.

The clear gel appears to be significantly more elastic than ordnance gelatin. I don't think it shows TSC very well.

I agree. The TSC is the biggest 'con' for the clear gel that I've seen so far.

[AndrewWiggin]

Not a big deal for testing pistol ammo and it seems that the clear gel shows comparable penetration and expansion figures there. As long as we know that TSC isn't going to be accurately portrayed in rifle tests, it can still yield good penetration and expansion/fragmentation numbers.


How did you determine the point at which the jacket separated or was that just where the first jacket fragments came to a rest?

Keep in mind that Clear Ballistics blocks are not an "FBI spec gel block".

4LD is a simple engineering test to assess handgun projectile resistance to plugging with clothing material--this is not an issue with rifle projectiles; as such 4LD is NOT a necessary protocol when testing rifle loads.

So far, NONE of the polymer gel blocks accurately represent TSC in static testing.

A minimum of 5 rounds are needed to get a sense of how a projectile is going to perform.

Party pooper!

I appreciate you taking the time to contribute here, sir. I always pick up a little knowledge when you do.
