Default FMJ for concealed carry?

Who carries FMJ for concealed carry self defense..?

The argument AGAINST carrying FMJ is the same argument FOR carrying FMJ..

Penetration..

Some fear over penetration with FMJ while others use FMJ to make up for the lack of penetration...

.45 for example has fairly low penetration (compared to 9mm, .40, 10mm, .357, etc.)

Did you know that 6 out of 7 people shot by a handgun survive?

If course shot placement is of utmost importance, but penetration is key..

Is it safe to say that FMJ is good to carry for cartridges that have lower penetration and JHP for speedier bullets?

For example, carrying .45 FMJ but JHP for 10mm..

Is this philosophy flawed?

Thoughts..?

Most ballistic tests indicate that 45 ACP has the same or greater penetration as most other ammo types, and in addition has a larger wound cavity causing more tissue damage and a greater chance of stopping an attacker.

This is only true of those shot with a single bullet, morbidity is 18%, but those shot with two or more bullets morbidity is 80%, it is not the bullet type or caliber but the amount of damage.

Yes it is flawed!! First humans are not sacks of gelatin but bones, flesh and organs each having different densities, second faster bullets have a tendency to go through a humans doing less damage than slower bullets that expend all their energy within the human frame. Third larger holes mean bigger wounds and bleed out faster.

I will stick with the 45 ACP hollow points for larger holes, more damage to tissue and the ability to break bones while traveling through different levels of clothing, bone and organs.

Just my take on the issue.
Jim

I have read many of the posts regarding bullet types, weights, penetration and types.

As bigjim suggests we are not gelatin. I'm not the smallest person in the world but I often wonder why we need 12" penetration. That would almost go all the way through me if not certainly deep enough to damage vital organs.

Some of the diagrams I've seen show direction from the top of the shoulder which could happen but I visualize more likeliness of an upright criminal and aiming for the torso area should be the best shot.

Of course we may not always get to pick and chose our situations.

For 9mm and higher I'd go hollow points

for .380 and smaller fmj for sure

12" of ballistic gel is about the same ammount of force needed to penetrate one arm and reach the vitals. Its done from a worse case aspect. Goblins arent going to stand straight up face to you arms to sides hanging loose...

You need a round that will go 12+ inches in gel to ensure its got enough energy to penetrate an arm bone from the side pirce a rib and get into the heart lung area.

Most hp will do this in 9mm on up. Exceptions being things like glaser safety slugs those ridiculous ripper rounds and other nonsense.

In rounds smaller like 380 32 25 the hp offerings lack the ability to get to the vitals reliably. Thats why you use fmj for this. Its also why you dont use birdshot or shot less than 00buck in shotguns.

My EDC is a tool of many tasks. Usually have FMJ's. cheaper, feed nice.

If I am on the property and pop a few rounds at a stump or a mole, FMJ's work fine. Same ECD goes to HomeDepot, SafeWay and the local feed store.
If a bad guy needs to get shot, it'll probably be a FMJ.

First, HPs don't feed well in many 45s, which makes FMJs pretty

much the order of the day, for them.

Second, my ballistics show the 45 with much less penetration

than most faster, smaller rounds, or magnums, driven by 4 or

5 times as much powder.

Consider this, most SD scenarios are going to happen when you are

alone and isolated. BGs don't want the extra attention a crowd brings.

So Mrs. Inne O. Sent isn't going to be standing behind a bad guy,

when he makes his move.


As to "speed" and HPs, when you are talking FPS, speed is the HPs

enemy. A HP expands much better at 45ACP speeds-@850 FPS, vs

@1400FPS of faster, smaller calibers.

I can see why you might think this way, but there are a number of factors to consider. The distance from sternum to heart is far less than 12", true. It is not just depth of penetration, but depth of penetration in ballistic gelatin. Gelatin does not have bone. Bone can be very difficult to penetrate. I have seen a sternum with a .357 Magnum bullet stuck IN it. I have seen the base of a .38 Special Silvertip visible ABOVE the skin between the upper lip and the nose.

The magic 12" figure just equates to sufficient energy to penetrate to the vitals from ANY odd angle. Upper arm (including the humerous), rib cage, several inches of muscle and fat alone the way across the thoracic cavity to the heart AND penetrate it completely? Yup, 12" is about right.

As far as speed being the enemy of a hollow point bullet? That kind of thinking is about 20 years behind the times. Modern bullets utilize "controlled expansion". The size and volume of the hollow cavity and the design of the serrations in the jacket are carefully thought out to allow for expansion AND penetration at expected impact velocities. I remember when the .45 ACP had a reputation for INSUFFICIENT velocity to expand at all. Now it is the only thing that will reliably expand?

Any good bullet design like the Speer Gold Dot, Federal Hydra-shok, Winchester SXT or Hornaday XTP can be expected to give proper results nearly EVERY time.

As for the smaller calibers, carry FMJ's, cast flat points, Speer God Dots, stagger HP/FMJ, but be prepared to shoot MULTIPLE shots INTO the target (not just AT the target). .380 and smaller should NEVER be expected to stop the threat from a single shot. On those rare occasions I carry a .380, I fully plan on emptying the magazine (12 rds) into the goblin and still have to beat his bloody azz down to fully stop the threat

I keep my magazines loaded alternating between JHP and FMJ.

I feel that keeps me better prepared for whatever situation might present itself.

What type of clothing will the BG be wearing: thick layers of sweatshirts, thin t-shirt, heavy leather jacket?

Where will the round strike first: thick bone of upper arm or leg, soft tissue of stomach , skull, hand, ....

If one doesn't do the job....hopefully the other will

Robo:Which 380 has a 12 rd. Mag?? I only know About the Beretta(13) and the Bersa Thunder +(15).

I don't carry 38 as an EDC anymore after a friend of mine was almost a hit and run victim of a drunk driver leaving the scene of an accident, while firing 5 Rds. From his off-Duty Smith 38, and only one went through the Auto Glass of the car.
I alternate FMJ & HP in 3 Mags,..and one full mag of FMJ's and one of just HP's. Since my 2 Main EDC's are both Single Stack 9's, I never carry less the 4 spare Mags at any time unless carrying at home.
My personal HP choices( and I spent 8+ months testing out whatever I could get my hands on in 9MM for an Article here I never finished!):
Hornady Critical Defense & Critical Duty, MagTech, DRT's ( light power charge tho, jams up heavier spring guns), Fiocchi 115, 124, and 92Gr. Rounds, and just about all the Federals's. I found the Remington Golden Sabers, while a very good round, sometimes Jammed up Semi's in Rapid fire because of the wide-ness of the HP cavity, and was 2X the price of every other round. The GS's are good in Wheel Guns tho if that me and anything....
The Liberty defense rounds deserve a mention here as well...
