Gelatin tests: .357 mag from carbine & 10mm 155 gr XPB

[chopinbloc]

.357 mag American Eagle 158 gr JSP fired from Marlin 1894C 18.5" barrel lever action carbine into calibrated gelatin.

BB: 585.6 fps, 3.7"

Impact velocity: 1,840 fps
Penetration: 15.1"
Retained weight: 153.8 gr
Max expansion: 0.892"
Min expansion: 0.674"







10mm Littlestone 155 gr Barnes XPB fired from 4.5" EAA Witness through four layers of denim into calibrated gelatin.

BB: 585.6 fps, 3.7"

Impact velocity: 1,128 fps
Penetration: 12.8"
Retained weight: 155.3 gr
Max expansion: 0.751"
Min expansion: 0.470"


For comparison, here's an older test of the same load from a 4" revolver:




Federal American Eagle 158 gr Jacketed Soft Point fired from 4" S&W Model 13 into calibrated gelatin through four layers of denim.

BB calibration: 607 fps, 3.4"

Impact velocity: 1,182 fps
Penetration: 22.1"
Retained weight: 157.3 gr
Max expansion: 0.398"
Min expansion: 0.363"

Im surprised at the .357 Mag performance. The velocity is much higher than I would expect from a factory soft point, and its performance isn't that far from a good 7.62x39. I can understand how it would be a great deer round inside of 50-100 yards.

Nice documentation, good job. I love video experimentation.

Holy cow! That .357 carbine result was impressive!! I never expected the block would jump off the table like that.

I calculate that a 158gr at 1840 fps gives 1188 ft-lbf energy.

I've always wondered if those JSPs would expand (I use that Federal round a lot at the range actually).

Guess that's one question answered!

 

[chopinbloc]

Yeah, that's what we got. I was pretty surprised too. To put that in perspective, .223 PMC Bronze 55 gr ball from a 16" barrel gets about 2,835 fps at the muzzle for 981 ft/lbs. At 3,000 fps, that 55 gr bullet has about 1,100 ft/lbs. Not accounting for the dramatic difference in wounding mechanism, in terms of just energy, this .357 load is more powerful than .223.

 

[JTHunter]

What caught my eye was the greater penetration from the pistol vs. the carbine (22 vs. 15").
That may be due to the greater expansion from the carbine of (avg.) 0.783" vs. 0.381".

 

[DeMilled]

It would be nice to see that 10mm fired from a carbine into the gel.

 

[chopinbloc]

JTHunter, that's exactly correct. If a bullet is capable of expanding, it will generally penetrate more at lower velocity. Another interesting phenomenon is that JHP usually penetrates more after passing through denim. Modern JHP are perfectly capable of still expanding after heavy clothing but it usually delays expansion, increasing penetration.

DeMilled, I really want to get hold of one to test. I'll be borrowing my uncle's Hi-Point 995 and KelTec Sub 2000 in .40 S&W to do some testing soon.

I'm in a fog of cold and flu meds... how much did the 4" inch revolver beat out the 10mm? .... never mind I see the data now thanks

 

[SharpsDressedMan]

Mech-Tech makes a 10mm upper for Glocks and 1911's, I believe.

 

[chopinbloc]

It's not really offered as a comparison. Two completely different bullet types.

 

[stressed]

Thanks for the carbine tests.

You plan to test a 9mm carbine? Those results have me curious.

 

[chopinbloc]

Yessir. My uncle has a Hi-Point 995 and a Kel-Tec Sub 2000 in .40 S&W. I intend to test both.

 

[stressed]

I would go in with you for clear ballistic gel. Also cull pig and cattle for butcher (real flesh tests) however not sure how that would go over on here.

Here is a link with carbine and various ammo. I have about 20 more to test now.

Oh yeah, the .357 magnum is one hot little number coming out of a 'bine bbl! It's also plenty potent coming out a REVOLVER barrel!!!

 

[Mastodon]

Good to see! As I have that very carbine, Model and Make.
.357 mag coming out of an 18.5 barrel isn't bad, and never has been.

Thanks for sharing.

 

[chopinbloc]

Stressed, thanks for the offer. I've thought about it because Cleargel is supposed to be able to be reused far more times than gelatin but I've noticed some discrepancies in other peoples' Cleargel tests when compared to professional gelatin testing, especially where rifle or high velocity handgun cartridges are concerned. The gelatin is more work but I don't really mind because I think it yields more accurate results.

It's funny you bring up the 9mm carbine tests. My uncle just lent me his Hi-Point 995 and Kel-Tec Sub2000 in .40 S&W today so I hope to get some 9mm and .40 S&W gel tests done soon.


Thanks for looking, guys.
