Fragmenting self defense ammo...

Corbons JHP seem to fragment on a regular basis.

I know they do not usually hit the 12" minimum penetration depth.

Does the violent fragmentation of the bullet cause significant enough damage to off set the lower penetration depth's?

Overall will corbons jhps cause more damage by fragmenting than a traditionaly jhp that stays together and penetrates deeper?
 
Are you talking about a particular caliber & weight, or preferably, do you have a link to the specific studies you're using as a basis for your conclusions?

I've seen lots of tests of Cor-Bon JHP ammo that showed 100% weight retention (i.e. no fragmentation at all), but unless we know what caliber/weight you're talking about, they may not be relevant.
 
I am not talking about the dpx line . I mean the standard jhp's.

especially in 9mm, .357 sig and .40 10mm anything less than 180 grains seems to fragment violently.
 
"Does the violent fragmentation of the bullet cause significant enough damage to off set the lower penetration depth's?"

No.

What would it really damage?

Skin?

In order to effect a stop, you have to interrupt VITAL body systems.

Surface penetration won't get the job done, unless the fragmentation is violent enough to blow the individual's bones and organs OUT of the skin, leaving a skin sack on the ground.

The lowest acceptable.

The lowest limit.

The smallest acceptable amount.

Smallest recommended distance.



Enough said.

Just go buy a couple different boxes of whatever modern HP ammo from a variety of manufacturers. Other than your gun shooting one a "little more" accurately, the ballastics and performance will be very similar and be fine. The slight differences won't be noticed or appreciated by a bad guy or coroner.

If you want a few choices, here are some (well regarded) that will give you a "sampling" of different design concepts (the final results will be about the same though) for HP ammo. Try want them and buy more of the one you like best.

Remington Golden Sabers
Hornady Critical Defense
Cor-Bon DPX
Federal Hydra-Shock
Speer Gold Dot
 
If the ammo doesn't meet your criteria, don't buy it. Any of the top brands (Corbon, Win., Speer, Hornady, and BB) will do the job nicely.
 
dear Super-Dave,

For the 56th time, please read this link:
http://ammo.ar15.com/project/Self_Defense_Ammo_FAQ/index.htm

you will find the answers to your questions by reading the above link


ps - fragmenting ammo like Glaser, Magsafe, RBCD and Extreme Shock is overpriced gimmick ammo. Terminally-speaking, more is being lost than gained by using "frag-nasty" JHP and pre-frag ammo.

If you do a proper search, "Super-Dave", you will find there are many threads on here discussing this very topic

Thanks for the link! I'm always looking for ballistics info, since most of what I know comes from conversations with more experienced shooters (some I've found not to be accurate). If you can suggest any others, please post them.

I will be using the search function.

Dave

Well, the lowest acceptable to the FBI. I think it's a guide that should be seriously considered but I would not automatically reject a load that only penetrates 11 inches.

I do agree that fragmentation in handgun bullets is not good. Momentum and penetration are lost. When you start getting into rifle velocities, there's a different dynamic with the M193 rounds being highly dependent on fragmentation, but at velocities of about 2,500 fps and greater.

I agree, were is he getting his info from?
 
I quit carrying 165 gr JHP CorBons in my G22 a long time ago because they consistently shed the jacket in casual water jug testing.
 
COME ON GUY'S

Super-Dave posts those questions to get people to THINK.
You all seen enough of his posts.

You all , need to give him more credit than what some of you are giving him I.M.O.

P.S. Super-Dave make them Work extra hard for it.
 
"Super-Dave posts those questions to get people to THINK."

Why do I suspect that that is really the FARTHEST thing from his mind?
 
Why are you all rippin' on Super-Dave?? Ad-homination going on here.

Although the topic has been discussed previously, it has not been "settled." Honestly, I tend to side with the school of thought which supports penetration over fragmentation, but that does not mean I am closed to other ideas.
