So back to Hp v ball...
So back to Hp v ball... What works in this small of a cal? Is there benefits to just wounding and would that work better?
And if it's a fmj it goes through more tissue, so which is best. I like more Tissue damage due to more depth.
Jhp may or may not reach a critical organ where a fmj will reach the organ and likely leave an entrance and exit hole in it. I like the probability of two holes verses a single and little larger hole.
There are a lot of different options and exotic ammo out there but does one really work any better than the other I don't know, personally I carry standard hollowpoints.
If a Winchester semi wadcutter will penetrate 16" of ballistic gelatin at a little over 800 fps, what would be the benefit of a little more velocity?
All this discussion of what this round will do and what that round will do imo is useless in 380.
The round is what it is and as long as it penetrates deep enough to hit something vital is pretty much all one can expect.
It might. Depends.
An FMJ doesn't necessarily go through more tissue. In a straight, frontal chest shot, the most any bullet can go through is the thinkness of the chest from front to back. If the JHP gets to the far skin, but the FMJ sails clean through, well, you have similar length wound tracks, even though the FMJ "could have" gone through more.
And then there's the question of downrange safety when a HC bullet that can penetrate over 20 inches of flesh and bone exits after going though a chest that's a bit over 12 inches thick.
In any case, my point was that the expansion of a slug does not compensate for poor aim. Or even for bad luck!
Unless you're clairvoyant, you cannot predict the exact circumstances of any self-defense situation you might find yourself in. Therefore, your goal in choosing a bullet for personal defense should be to select one that will be effective in as many different scenarios as possible.
Your bullet must be able to penetrate deeply enough to contact and destroy tissue that is critical to the immediate survival of your attacker.
The two most important factors in stopping a bad guy are: 1) where you place your bullets, and 2) what organs your bullets penetrate and damage.
How much penetration is adequate?
According to the nation's most prominent wound ballistics experts, your bullets should penetrate at least 12 inches of soft tissue. Penetration beyond 18 inches is considered too much, and a less penetrating design should be considered to optimize the cartridge's wounding potential.
But with small caliber cartridges such as .22 LR, .25 ACP, and .32 ACP (and sometimes .380 ACP), you're better off selecting a non-expanding bullet that might exceed 18 inches of penetration than to choose a bullet that expands and underpenetrates.
When a bullet expands, the increased diameter and non-aerodynamic shape acts like a parachute to quickly slow and stop the bullet as it penetrates flesh. These tiny bullets lack the mass and momentum to achieve adequate penetration after they expand.
Bullets that meet the 12-18 inch penetration guidelines have proven to be very effective in police shooting incidents that have been investigated by reputable researchers who use the scientific method. These findings have been verified and validated by other distinguished wound ballistics researchers who've fully reviewed the data.
These findings are far superior in validity to the Marshall/Sanow "one-shot stopping power" junk-science that is published in newsstand gun magazines.
And if your on the Hornady Critical Defense band wagon you might want to look at this article
guy wants a simple suggestion or two on opinion as to the quality/reliability of a cartridge for a .380. 15-20 opinions about hot air, and whichever goes the straightest, and other buffoon-sent answers.
Does anyone have an opinion as to the better shot? I like Speer Gold Dot.
That 1/7 of an inch could mean life or death, especially where shot placement is concerned. I would not forget that. When we are talking about a 2/7" diameter increase across the face of the slug during expansion, that may be the tissue destruction factor needed.
As for my subjective answer to the OP, I prefer Speer GD. Shot into wet pack, it is quite devastating, Dow what it is. Yet I agree with kokapelli, shot placement is key. Although, has anyone researched
whether or not hydrostatic shock apllies to .380?
Edit: Looked for myself, and sadly it does not contain enough mass or velocity to induce hydrostatic shock.
This is my choice as well for my 380 pistols.
Hope it helps, I'm going to try out the author's recommendations for my p3at.
Speer Gold Dot expands the most while penetrating the deepest.
I highly suggest you look at his work at KTRange (though he posts in KTOG) before you take any random advice here.
Search KTOG on the issue. Quite well known even if you didn't know.
Old Grandpa uses wet packs (newspapers) to test bullet performance and IMO there is just no way to get consistant results with different bundles of soaked newspapers.
Also wet newspaper isn't in anyway similar to human tissue.
If you want to know how a bullet will perform in real world conditions, find calibrated ballistic gelatin test results instead of bundled wet newspapers.
As far as it goes this is likely true however death of the assailant isn't a requirement for successful self defense. Most handgun shootings are not lethal and certainly not immediately lethal. The purpose of using JHP is that it makes a larger hole and if you have to rely on circulatory system depletion to stop the assailants agression then a larger hole brings that on faster.
At best a JHP will expand and produce a large wound cavity, at worst its hollow gets plugged or closed off and fails to expand so it acts as a solid nose bullet. Solids never expand and have no opportunity to produce a larger wound cavity.
