Given that this has been the result for every test that you've run of late, I have to wonder about the ability of the test materials to mimic real life. I have no doubt that bone plugging is an issue with HPs, but cannot believe that it's as consistently an issue as you're seeing in your tests.
 
Geeze! GD's failed in your .45 test and here too? You have me rethinking my go-to ammo choices.
 
The three most important things affecting a bullet's effectiveness are: placement, placement and penetration!

Forget about "magic" bullets and ammo too expensive to practice with.

Good point. I hope that the situation in the 'real world' is not this dramatic and that JHP expansion happens more frequently. A similar argument occurs with ballistic gelatin as a simulant medium. IE "how good can it be, because it doesn't contain bones and isn't always covered in clothing?"

My question to that is "which shotline should we model?" There are likely hundreds of possibilities. Examples of the various shotlines would be a straight-on shot to the forehead, another shotline could be a clinched fist (holding pistol) in front of head as one would do when shooting from prone. Turning the original headshot to a 30 degree angle (if the target was using a Weaver stance), which would increase the apparent thickness of bone needed to be penetrated. Add in some that you come up with and we're talking some serious testing needed to get answers!

So that's the issue of generality vs specificity. The FBI standard approaches the general, other wound ballistics concerns deal with specific shotlines. I'd like to repeat the same tests (with the same ammunition) against Synbones round simulated bones. This cannot happen without money, though, so we will need someone or group donation from THR users to fund further bone testing.

I did some testing on wet paper in water jugs and the dpx was the winner in that one as well.

Best expansion and best penetration of the 4 I tested
 
Still sticking with WW Ranger +p Bonded in my 9mms, but the DPX looks good and if I lived in NJ there would be but one choice!
 
Going in 3" into the jello, veering off an exiting the block is "weird."

We had a shooting a couple of years ago where shots were fired at the driver of a vehicle, but his front passenger ended up taking one in the head. I can see one of these DPX bullets going through glass, striking the assailant, exiting off to the side, and causing a multi-million dollar problem.
 
Wow. I've been saying for a while that I have been thinking of switching my SD/CCW load from the .40S&W 165gr. Gold Dot, to 165gr. Fed. EFMJ especially for winter time so I don't have to worry about a hollow point clogging.
I kinda see the EFMJ as a less expensive alternative to the Critical Defense. Same concept, but I can get 50 round LE boxes for under $30. Works for me.
 
Who developed Synbone? How was it developed? How does it compare to available results concerning actual shootings? A link to this info would be nice.

The results do not seem to mimic actual shootings from what I know.

Why so specific of a target?

I'm looking at this summary of the FBI Miami Shootout in 1986 : http://www.firearmstactical.com/briefs7.htm

Below is what is said there about the locations of the wounds of the FBI agents in that fight :

Richard Manauzzi - Injured (unspecified injuries).

Gordon McNeill - Seriously injured by .223 gunshot wounds to the right hand and neck

Edmundo Mireles - Seriously injured by a .223 gunshot wound to the left forearm.

Gilbert Orrantia - Injured by shrapnel and debris produced by a .223 bullet near miss.

John Hanlon - Seriously injured by .223 gunshot wounds to the right hand and groin.

Benjamin Grogan - Killed by a .223 gunshot wound to the chest.

Gerald Dove - Killed by two .223 gunshot wounds to the head.

Ron Risner - Uninjured.

The only person listed as having been shot anywhere in the chest was Benjamin Grogan. That is 1 out of 7 of the injured people, or 14%. Why the specificity about a certain area on the sternum?
 
These tests are always interesting to read about. I do my own informal tests using various mediums for my own entertainment.

However, when it comes to bullet selection, I've decided to pick the most affordable of quality (factory loaded) JHP, preferably something that's used by several agencies (to keep production up, costs down).

I'd done just this with my carry pistol (M&P40c, XM40HC) and spend more time focusing on maintaining/increasing proficiency. It's one thing to test various JHPs for fun, it's quite another thing to fret over the results. Pick a decent JHP, stock up if you can (or reload an equivalent) for practice and don't look back.

Thanks for your contributions, JE223.
