200 XTP at Underwood velocity (1200 FPS). This is the PBR version, but same bullet and par velocity:




Raggedyman has versions of the other two when he can get to them. It seems the 200 XTP won't really expand at speeds under 1175 FPS.

Can I request a 200gr xtp underwood tested in real gel with 4 layer heavy denim?  It didnt penetrate as much as I thought it would in tnoutdoors9 test.  Also just a standard hornady custom factory load 180 and 200gr xtp would be nice. Or roughly 1180 fps in the 180gr and 1080fps in the 200gr.

Hunter published a fantastic article on Hornady 10mm XTP ammo performance in clear gel.

RaggededyMan, that 135gr Miyhec looks like it turned inside out.  Great video, thanks for posting.

Yeah, that was nuts. Here are a couple better quality pics:











(Is there an echo in here?)

Yeah I saw hunters test. That 180 xtp looked mean in that.  I was just hoping for a ballistic gelatin test not a clear ballistics test.

I was actually planning to do the Hornady factory 180 gr XTP test yesterday when my buddy talked me into testing the 135 gr Mihec. Maybe I can do that one next time. In the mean time, I did do the 180 gr XTP at 1,290 fps (factory 180 gr XTP chronos at 1,155 fps). I think that was the first gelatin test I did, actually.

How do you guys like the addition of the water portion? Is it fun? Stupid? Waste of time?

If it isn't stupid or annoying, I hope to start building up a library of water vs. gelatin tests to hopefully give a rough approximation of penetration depth in water vs. gelatin. The whole 1.6-1.8 factor (water:gelatin) is clearly not linear but with enough data points, maybe we can develop an idea of what the curve looks like.

The water jugs are neat to see in person and especially on camera.  I can see where it would present a situation of hauling even more stuff out to the range and back as not to leave junk lying around!    Being able to see the hydraulic/cavitation and exploding jug effect is very interesting!   The water is hard on the projectiles, sometimes they will yaw and/or exit out the side or strike the bottom.

If ever I get the CONEX container range established, I may switch to "jello shots" for bullet capture.  Till then I use the water jugs...

Cool. If you've shot into water some of the same loads I've tested in gelatin, I'd be interested to hear the results.

Chopnbloc/raggedyman did that 180gr xtp hornady custom really go over the chrono at 80fps faster than advertising velocity?  I thought I remembered it was 1180fps on the box.

It appears so. I was surprised myself. It was warm and warm weather can produce higher velocity but it's a pretty big difference.

Damn good load right out of the box, imo!! thanks for posting that.

What's you're barrel length again?  Hunter got 1162 and TNOUTDOORS9 got 1155 (glock 20) on their test of this load.  Box says 1180.

Maybe Hornady juicing them up a little after emergence of Underwood, PBR, etc...

Where did this one come from?

4.5"

Wife bought them locally about a year and a half ago.
