Buffalo Bore 180 gr Sierra Power Jacket

10mm Buffalo Bore 180 gr Sierra Power Jacket fired from 4.5" barrel EAA Witness through four layers of denim into calibrated gelatin.

BB: 599.2 fps, 2.9"


Impact velocity: 1,311 fps
Penetration: 10.7"
Retained weight: 181.1 gr
Max expansion: 0.853"
Min expansion: 0.560"




Selway 180 gr JHP

10mm Selway 180 gr JHP fired from 4.5" barrel EAA Witness through four layers of denim into calibrated gelatin.

BB: 599.2 fps, 2.9"


Impact velocity: 1,105 fps
Penetration: 12.9"
Retained weight: 175.2 gr
Max expansion: 0.678"
Min expansion: 0.600"






10mm 180 gr Winchester generic JHP hand load

10mm Winchester 180 gr generic JHP loaded over 10.0 gr of AA#7 fired from 4.5" barrel EAA Witness through four layers of denim into calibrated gelatin.

BB: 599.2 fps, 2.9"

Impact velocity: 1,106 fps
Penetration: greater than 16"
Retained weight: N/A
Max expansion: N/A
Min expansion: N/A

The bullet experienced significant fragmentation and deviated from its path, exiting the block at about the 16" mark. A second shot performed similarly.

Thanks for the new test, Many are waiting for the Speer 200 gr Gold Dot hopefully around 1200 fps.
Good luck!

Maybe you could couple the next three GD200, Underwood XTP 200 and Gas Ammo 200?

[Raggedyman]

Good plan. It won't happen until the Witness comes back from EAA, though. I'll test the .357 and .44 loads you sent in the mean time.

Why is it the faster bullets tend to penetrate less?  Doesn't make sense to me.  Then some test I see a slower round will go just as deep (Hornady 180 vs. Underwood 180).  Then hot 180 goes deeper than hot 200. Then .357 magnum 125gr deeper than 135 10mm.  Hmm....

   That high speed impact makes the "parachute" open up quicker. From what I have seen the 200 XTP seems to take more speed to open up really good. That's one that may work about perfect at 1300 FPS.

Exactly, for a hollowpoint.

And with a full metal jacket bullet, the extra velocity will drive it deeper into tissue.

I wouldn't wanna be hit by that Buffalo Bore round. The penetration was lacking a bit, but that is one helluva cavity.

That Sierra bullet I don't think is bonded and held together really good. Wonder if they make a 200gr version?

Don't Know.

Nosler makes a 200 grain JHP though. This is the one Double Tap loads in their 10mm. I would love to see that bullet torqued up to 1200 fps and fired into gel.

Did you see the video Raggedyman did on it?

[4949shooter]

On the Doubletap load, or on the Nosler?

Either way I must have missed it.

Thanks IC.

The other guys covered it pretty well. Extra velocity in a JHP typically results in less penetration due to earlier and wider opening. I'd like to add that a .357 bullet of similar weight, construction, and velocity will typically penetrate more deeply than its 10mm counterpart because it is narrower and thus has a higher sectional density.
