10mm gel tests

Raggedyman · December 24 2012 08:24:28 AM MST

I missed the velocity on the Precision One load. I copy/paste descriptions from older videos and just change the data but somehow I left the data in the description on that one. Derp. It's fixed now. I'll update it with your result so people at least have an idea of the neighborhood it's in.

I do have a .357 and I've been wanting to do some .38/.357 tests. Especially the 158 gr JSP. I also want to gas up the 200 gr HAP and XTP to see what I can get.

Here's the Underwood stuff from the video description:

10mm Underwood 155 gr Gold Dot. Average velocity was 1,448 fps. Fired from EAA Witness 4.5" barrel through 4 layers of denim.

BB calibration: 592.6 fps, 3.25"

Impact velocities with penetration depths:

1,449 fps, 10.25"
1,459 fps, 10.25"
1,436 fps, 9.75"

Maximum/minimum expansion and retained weight measurements follow but I can't tell you which bullet is associated with which shot.

0.970", 0.548", 154.5 gr
0.944", 0.567", 153.5 gr
0.951", 0.569", 155.3 gr

I have them all in. PPU will be interesting.

What else looks like a good candidate?

Can you give me a link?

Frankly, I think the PPU might make a decent self defense load if the bullet performs consistently. I think I'll be using a 165 or 180 gr Gold Dot at very moderate velocity for my personal defense load and either the 200 gr HAP or XTP for woods defense. I don't believe that the extra power that 10mm produces is really all that useful for defense against humans because it isn't powerful enough to produce a TSC that can significantly effect wounding. The extra recoil just slows down your shooting. I think the FBI had the right idea with their FBI lite load. What's attractive to me, though, is that I can carry one handgun that is useful for both personal defense and large animal defense by just switching mags. I look forward to seeing how the PPU does... if it doesn't blow up my gun. ${$default_shocked_smiley}$

No worries. I only heard the one incident and it was a Glock which is hard to tell.

What is HAP? Are you buying all Copper bullets to load up?

Raggedyman · December 24 2012 11:43:24 AM MST

HAP = Hornady Action Pistol, which is very similar to an XTP but without scoring. It's not designed for expansion, but for competition. If my last test can be believed, it looks like it may be able to expand, especially if I drive it even faster. I'm going to push the XTP and the HAP a little faster and see if I can get up in the neighborhood of Kevin's loads. I'll be happy if I can reliably get 17" or more penetration combined with some expansion.

Did you post the data into a spreadsheet?

HAP (Hornady Action Pistol) bullets are the same as XTP, without the skives (precut/sectioned tip). They expand very well at high velocity in tissue, but much less consistent than the XTP, or a bullet designed for controlled expansion.

I see them now. Like a Nosler in construction.

Last column on every sheet.

Awesome. Thanks. Can you add the data from the other ones I've tested?

Intercooler · December 24 2012 03:32:57 PM MST

Everything in the videos was added.

Raggedyman · December 25 2012 01:47:46 PM MST

There are tests of loads that aren't on that list. For excample, the MAC Razorback.

Intercooler · December 25 2012 02:03:46 PM MST

Its on the other tabs at the bottom in the 165 section.

Raggedyman · December 29 2012 01:20:02 PM MST

Duh. I didn't even notice the tabs for weight. Thanks a bunch. That was a lot of work. I hope you don't mind if I re post this. Will the same link point to the updated version if you add more data to the spreadsheet?

Raggedyman · December 29 2012 01:28:35 PM MST

One correction: the expansion figure on the BCSP should read 0.40", not 0. Again, great work. How can I make the columns wider?

Intercooler · December 29 2012 01:55:11 PM MST

Yea it will update when it's added to. You can save a copy and widen them or let me know which ones and I can try.

Any plans to do the PPU? I will change the BCSP info now.

Raggedyman · December 30 2012 02:16:43 PM MST

Not a big deal. I know what the columns are. I'm just not real familiar with Google docs.

Yeah, I think I'll do the PPU on the next test. I don't have much left to do. I'm gonna up the powder charge on the 200 gr XTP and HAP to see what I can get out of it and I do want to get around to the 220 gr hard cast eventually. I think what I'm going to do is mix up a bit more gelatin, cast into the old tubs I used before, cut off the edges straight, wrap in Saran wrap, recast the excess, etc. I should end up with several feet of gelatin. I just hope the path stays straight enough. Any bets on how far it's gonna go?
