9mm Hollow Point Expansion Test – Under Water Slo-mo!

The cast bullet for this 9mm is a from an NOE TLC357-135-RF RG2 mold. This mold comes with 3 pin sets. One for flat points making 140gr bullets, one for shallow points – 135gr, and one for deep hollow points – 126gr. All bullets shot today where cast with air cooled wheel weights measuring roughly 13 bhn. Powder charge was 3.5gr of W231 using CCI 500 primers inside mixed range brass. COAL at 1.041″
I managed to capture some really awesome footage which replicates the same results and looks of shooting into ballistic gel. Oddly enough the hydraulic expansion of just shooting into water verses gel medium shows some devastating damage. I hope to try more of these test in the future at higher velocity cartridges such as the 350 Legend.

Shooting and cleaning your gun at the same time. Great video, those deep hollow points look pretty awesome.

That was a great test Eagle Eye! I tried to video bullets going through water last summer. I took a tall trash can and cut out a 12″ x 36″ rectangle. I bolted and siliconed in a piece of plexi. There were too many bubbles to see what the bullet was doing. Do you think my inflatable hot tub will work? Lol

The donut of air was awesome. Any damage to your swimming pool? The expansion of those deep hp bullets was perfect!

KENNY, THAT WAS GREAT! What a difference in expansion coming from the deep HP’s.
What kind of camera did you use to get that fantastic photography, the stills and slo-mo?
That sure made a Monkey out of my guessing that it’d take about 1,100 FPS to get them to open up.
Outstanding again!
