OTM rounds will fragment and that's a given, but the other guy said he recommends FMJ rounds for defense...very poor choice.
equation. I don't know the manufacturer, but I am sure you can google it and find out. Hold over in a stressful home defense situation is just not
practical for most people.
Home defense suggestion: Full size .45 or .40 cal handgun with attached weapon light, with access to an AR with attached weapon light.
Add lasers if you want it can't hurt but a weapon light is a must.
It is also FACT, not opinion, that a 5.56X45 is by DEFINITION not a "high powered" rifle round. It is, by definition, an intermediate cartridge.
Intermediate cartridge - Wikipedia, the free encyclopedia
Do your homework. Your opinion means nothing, it's facts that count.Quote:
An intermediate cartridge is a military assault rifle cartridge that is less powerful than typical full power battle rifle cartridges such as the 7.62x54mm Rimmed, UK .303 or US .30-06 Springfield, but still significantly more powerful than pistol cartridges. As their recoil is significantly reduced compared to high power rifle cartridges, fully automatic rifles firing intermediate cartridges are relatively easy to control. However, even though less powerful than a traditional rifle cartridge, the ballistics are still sufficient for an effective range of 250–500 metres (270–550 yd), which are the maximum typical engagement ranges in combat. This allowed for the development of the assault rifle concept, which is a selective fire weapon that is more compact and lighter than rifles firing full power cartridges. The first intermediate cartridge to see widespread service was the German 7.92x33mm Kurz. Other examples include the Soviet 7.62x39mm used in the AK-47 and AKM series, and the .280 British round developed for the EM-2. The 5.56x45mm NATO cartridge is also an intermediate cartridge.
Anything that can reach vital organs, fragment creating secondary missiles, and turn temporary stretch cavities into permanent crush cavities technically is a very good self defense option. While there have been talk about the bad performance of the 5.56 there are also folks that have also used it and it has performed very well. Typical human behavior though is to only report the bad, and never say anything that is good!
All I was doing was pointing out a good article on the aiming and use of 1 option for HD. Not trying to change anyone's mind .
Improper use of sites is a big problem with AR's
When it comes to 5.56X45 you are spreading disinformation. That's what I'm trying to tell you. I am telling you proven facts. Are you listening?
I have my 1911 and P238 for HD with my AR15 as back up with 55gr FMJs
The fragments do not need to have a lot of power/mass in order to open up and damage a blood vessel. They do not have to damage hard bone or solid organs. Their "job" is to rip open as many blood vessels as possible in order to dump as much blood from the circulatory system.
Short of taking out a person's central nervous system (brain or spinal cord), massive and rapid blood loss is the second quickest mechanism of stopping an aggressor by initiating hemorrhagic shock as rapidly as possible. Small bullet fragments which break off from the main round does this quite well.
Funny thing about facts, you can find them in many, many places. If you don't like the wikipedia article (which is fully correct) then maybe you'd rather read this:
ASSAULT RIFLES AND THEIR AMMUNITION:
After World War 2 it was decided that we didn't need full powered battle rifles because the engagement distance just wasn't that far. They decided that the ideal would be something between a pistol round and a rifle round. When the M14 began to show weakness this was remembered and the next rifle fired an intermediate cartridge.
Do you really want more links? Or are you just busting my chops? If you actually want to learn about the history about this stuff then you can start by Googling the STG 44 and the7.92mm Kurz round.
ETA: I was reading Echo Four's link and it is full of information. Check out the first British assault rifle that was fielded briefly before the US made the push for the 7.62X51 as the standard NATO round. It kind of looks like a toy. It was chambered for the 7x43 cartridge that was just too far ahead of it's time.
