Deep penetration. How much penetration is effective?

[Lebaneseblonde]

Thanks,

I didn't want to try to track down the info.

I recalled the 12" mark But I would be damned if I would be able to find it.


Cavitation is a very important component to organ injury inflicted.

thisis why high velocity rounds are regarded as so injury causing vs. heavy and slow approach.

Heavy is good as it continues momentum well when coming on a target, however it will have less velocity as it travels through a target than a lighter round that reaches equal depth.

This could go on and on, with sectional density, general terminal ballistics of both the target and the projectile, and on and on.


I carry a 380 with rounds that get pretty deep (per testing), are shaped well to feed in my firearm, and give back some of the penetration of a FMJ for an increased wound path that the leafed hollow point offers. However, many thing a FMJ is needed in a .380 because of it's lack of KE versus larger rounds. And there is good logic to that. Personally, I like the idea of a larger channel and petals that may come off causing secondary wound channels, leading to quicker exsanguination or neuro injury.

There are times when Solids or partitioned bullets are needed (thick skinned game, Large Dangerous game), but generally if you can get a round to deliver all of its injury without pass through (lost KE), then you will generally get best results.

Using the same logic, finding a round that will slow enough to deliver all it's energy is what you are looking for.

Good luck in the search!

As for me, with a 9mm, it is +P hollowpoints, or polymer filled hollowpoints

G2 rip ammo?

everyone's different. all depends on how deep and sensitive the cervix is.

LOL,

No Hornady or Speer for my 9s, Remington Golden Saber for my .380

Just take yer knife and cut lil' X's in yer rounds!

[Title1guy]

I've found that the various Federal HST JHP ballistic test results are enough to make me feel confident in using them with my carry 9s.

A lot.

Whatever caliber the gun is that I have to use to defend myself, I want a deep full-caliber (at least) hole, even if it means there's a chance a bullet will go all the way through. GlockN'Roll's quote from the FBI protocol mentions that 18" is better, but most people read that to mean the somewhere between 12-18" is optimal. Nope: Deeper is better.

Of course placement is important, but is of little use if the bullet doesn't go very far. I suppose if someone got hit 128 times in the perfect spot, it would have an affect even if the bullets only went in 1/2", but that's not something to count on.

"Caliber" and placement is more important than depth of penetration.

A .50 hole an inch deep isn't going to incapacitate anybody unless psychologically. I'd much rather have a clean cut .38 hole all the way through, even if it was a wee bit off.

Will that let you become a person like other people?

Had to ask.

I thought g2. ... really? ... someone actually buys it?

How much?
All of it!


(I mean, personally I’m OK with 124 fmj’s because all I’m going to worry about is where they need to go).

Agreed. I have some of each of the 124 and 147gr.

When I comes to packing a 9. How much penetration do you look for in a effective round?

My defensive scenario is some bad guy breaking into my house. In cold weather, they are likely to be wearing a heavy coat. So I load my 9mm with 147 gr Winchester JHP for deeper penetration. In warm weather, a BG will be dressed in lighter weight clothing. That's when I switch to 124 gr Remington Golden Sabers with their explosive expansion.

Shoot what works reliably in your gun and test your ammo for accuracy and performance. Buy premium ammo for when your life depends on it.

A FMJ will travel further than a hollow point, but the hollow point will do more damage. Isn't that the "point"?

Pardon the pun indeed.

Hitting the target is one thing but most important is training and the mindset to shoot a human. The "fight or flight" kicks in and lots of people are not fighters even with a lot of ubercool tactical stuff.
