Also filmed M193 (didn't fragment) and 50gr TSX (don't get shot with that round) those videos will be up soon-ish.  




If you guys wanna see come cool photos check out Aimed Research, link is in the description of the video.  That's the guy I'm working with on these videos, he owns the Phantom cameras that cost upwards of $80k that were used in this video.

WTF?  Is there a secondary explosion as the gel contracts after the projectile has exited?

Yes. Observed often in Clear Ballistics, and sometimes even in organic gel.




Nice video. I'd like to see one with M855 for comparison.

Common anomaly with clear gel, no, your body does not become an internal combustion motor when you get shot.

I think that's the air in the temporary cavity igniting as the cavity collapses and the pressure increases.

Yes.  

 



The flash/explosion in the gel hasn't been very well explained so far.  The best explanation I have seen is that the hot bullet vaporizes some of the gel (which is flammable) and between the friction, heat of the bullet, and air being sucked into the temporary stretch cavity, as the TSC collapses it acts like a diesel engine and compresses the mixture of heated gel vapor and air until it explodes. You can see the exhaust gas exiting the entrance hole.

I agree that it is likely dieseling of vapor gel material.

At the apex of cavitation pressure in the bubble must drop really low. Some gel material turns to vapor. Bubble collapses, pressure rises and eventually the now-compressed and heated vapor ignites.

Hydrocarbons in the gel igniting from during compression of the TC.  Similar to engine knock.

The flashes are also observed, though much more rarely, in organic gel shot with high velocity rifles. I suppose pig fat can also be dieseled.

Though that is sometimes observed when shooting rifle bullets into water. It's a completely different effect, though.

Any chance of seeing that test in standard ballistic gel? I know that Dr. Roberts has not been impressed with the Clear Ballistics version's ability to accurately show tsc from rifle rounds.

Thanks.  Dieseling had occurred to me but I didn't know that the gel was flammable.  I was thinking powder residue or something.  Regardless, the video is a great instructional tool.

We qualified with M855A1 for the first time this year.  No major score changes across my BDE.  It did seem louder, but that is subjective.

Heavy penetration. Was there a little piece of bullet left near the front?
I noticed the tip separated from the back towards the back of the gel.

The steel tip came out of the side of the block, the copper slug penetrated straight through and out the back.

Where did the jacket chunks end up?

I'm curious how M855 would look in the same test. I expect better fragmentation damage and a wider permanent cavity... But probably less penetration by most of the projectile mass.

They're spread out in a star pattern

 





















M855 doesn't fragment as reliably or nearly as soon as this.  And it doesn't drive a copper slug 30" into gel.  The neck on M855A1 is about non existent.
