.30 caliber carbine: 110 grains @ 1860 FPS
5.7mm SSwhatever: 31 grains @ 2100 FPS Which one of these can be expected to do more damage to the Bad Guy? |
|
If its just joe gangbanger, than the .30 carbine
But if joe is toting body armor, then the 5.7 |

le·thal
adj. 1. Capable of causing death. 2. Of, relating to, or causing death. I'd say = |
|
Depends on what is hit. An arm wound with a 308 is less lethal than a heart hit with a 9mm.
|
|
.30 Carbine can penetrate Level III armor. |
|
|
I recently aquired an M-1 Carbine and it is now my home defence gun.
So, I was pondering ammo choice: hollow-point for maximized tissue damage, or FMJ for body-armor penetration. |
|
If I was unsure which load to use I would load alternate FMJ and hollowpoint rounds in the same mag. Then I would use double taps for intruders. Charles.

thats a new one to me |

Exactly. |

Justin, Posting factual information from recognised experts is no way to get ahead here. The bag guy will shit his pants and run away from just the sound of a 5.7 chambering a round. Seriously the 5.7 offers 22mag like ballistics. Whereas the 110Gn 30Carbine JSP is as good or better than most 5.56mm loads. everyone should red the link Justin posted BTW. |

|
Good info there, thanks. |
|
|
Good stuff in the link. I really need to get an ultimak and put an aimpoint on mine. |

|
Unless you're dealing drugs I doubt you'll have much reason to repel body armor clad home invaders. |
|

First of all .30 carbine round will be stopped by lvl III hard armor. Lvl IIIa armor is soft and is not rated for it but would probably stop it but their would be a greater chance of blunt trama.
The five seven has a very short list of known shootings. In every case exept the ricoche that turned into a leg wound, the person has died very quickly with very few rounds. The bullet design is what hails the wounding balistics in this case. |
|
KogaShuko, I use the terms 'Level III' and 'Level IIIA' interchangably as I usually refer to Level III hard armor as Level III+. Sorry for the misunderstanding. As far as Level IIIA "probably" defeating .30 Carbine, you are mistaken. Did you read the link?
Don't take this the wrong way, but posting erroneous advice can get people killed. AR15fan, Isn't this ironic. |

Or put in jail, or blown up... Please use your best judgement when dealing with potentially sensitive information here. |

Seeing as how I am a poor college student, for SHTF/HD I must rely on the only rifle I own.
A 1943 Inland M1 carbine passed down to me by my grandfather. I have made great attempt to learn its true potential - most of the info surrounding the .30 carbine round is gun shop BS. The .30 carbine round is a very potent round - as you saw above it can defeat level III soft armor, and still do damage when it gets through, unlike the 5.7 which as AR15fan pointed out, offers .22 mag performance. A .30 carbine loaded with federal softpoints is a great load for homedefense against almost any scenario. |

CORRECTION:
.30 caliber carbine: 110 grains @ 1860 FPS 5.7mm SSwhatever: 31 grains @ 2650 FPS ***** sorry for the error I meant to compare Carbine to P-90/5.7 AR |
|
The 5.7 was marginal at best before they stopped importing the good ammo; the stuff they import now isn't much when compared to the old SS192- which wasn't much to begin with.
Some Canucks took the 10MM and necked it to .30 cal. They got M1 Carbine ballistics out of a Glock 20. |
|
Phoenix has had some problems with up to 9 man home invasions, all wearing full tac gear. I can only presume that body armor was part of their gear. |

Combat Jack..just to bring you up to speed , SS195LF is the replacement to SS192 and is the same except for a lead free primer and is made in the U.S. by Fiocci
SS196 is the reduced velocity round (1650fps)made to make the antis happy, as it will not penetrate a LII vest and is is soon to be dropped for the SS197...40gr V-Max bullet @2000 out of a pistol barrel. There are other loads coming to take better advantage of the carbine and bolt action guns coming out. Here no matter how fast the .224 bullet of the 5.7 is driven it is still a .22 magnum to somebody hmmmmm lol at 2650fps like a AR57..this .22 magnum must be pretty good, Im gonna have to stop by wally world and get one. |
|
At what bullet weights? |
|
|
110. I found the website in a random search at 3 AM, and haven't seen it since. It was some B.C. competition shooters. Glock Talk might have some info, but that place is a circus, so I don't visit often. |
||
|
If you find that web site again, please let me know. Do you remember the search terms? Thanks Seth. Regards, Justin |

.30 caliber carbine: 110 grains @ 1850 FPS 5.7mm SS195: 29 grains @ 2750 FPS 5.7mm SS197: 40 grains @ 2600 FPS -DmL |
|
|
22 Magnum: 40 grains @ 1900 FPS, 24 inch barrel 5.7mm SS197: 40 grains @ 2600 FPS, 16 inch barrel -DmL |
|
|
It's been such a long time that I can't remember any of the details. Sorry.
|
|
No. The .30 carbine is 750 fps less velocity, and 2.75 times the weight of the 5.7x28 using the SS197. Using the SS195 it is 850 fps less velocity and 3.8 times the weight. Using either 5.7x28 cartridge for the comparison, your post is completely inaccurate. -DmL |

A .22 Mag will drop a deer dead. I can't say how I know.
I think that the M1 carbine is underrated. It has been overtaken by modern technology. However, many people place too much emphasis on GEAR. If all a person has is an M1 carbine, he is by no means unarmed. |
|
A brick will kill a deer. Do I have an LBV loaded with bricks? Not exactly. But yes, the M1 will work. |
|

Sounds like the 12 guage would come up a little short. I would want nothing less than a AR in this situation. A P90 would also be nice due to the 50 rounds and low recoil. At close ranges like within a house, headshots should not be an issue with a carbine like a p90. |

Police impersonation raids are nothing new. Few people are aware of how common they actually are though. Usually they go after only drug dealers, but that's not saying they don't make exceptions. The well developed groups are not short on equipment.
With that said, I'd rather not be shot by either. |

I personally think .30 carbine is under rated. I also think that both calibers have fairly narrow performance envelopes - they are compromise cartridges. That's not a criticism, within their particular uses, they do pretty good.
That said, if terminal ballistics of .30 were that much better, I would expect some higher rates of adoption. I realize the primary platform is dated, and to some extent non-economic. But, if within the constraints of design, .30 cal offered that much more, someone besides Israel (where the .30 has logistical and operational advantages) would have moved the design along. Interesting designs, but the Hezi SM1 and the Magal are evolutionary dead ends. I think on some theoretical level, .30 carbine has the edge. But theres more to the package than merely muzzle energy. Practically, as born out by its adoption by plenty of top tier users, 5.7x28 does everything it needs to do and more. Could someone post a comparison of ME for like barrle lengths .22WMR and 5.7x28? I keep reading the purported similarity, but from what little I found published, its not correct. Thx Alac |
|
Here it is Alacrity, out of rifle barrels. The 5.7x28 produces basically twice the ME of the .22 WMR despite being fired out of a barrel 8 inches shorter.
22 Magnum out of 24 inch barrel = 320 ft. lbs (40 grains @ 1900 fps) 5.7mm SS197 out of 16 inch barrel = 600 ft. lbs (40 grains @ 2600 fps) 5.7mm SS190 out of 16 inch barrel = 520 ft. lbs (31 grains @ 2750 fps) -DmL |

Pistol barrels. Once again the 5.7x28 is far ahead.
22 Magnum out of 4 inch barrel = 185 ft. lbs (40 grains @ 1450 fps) 5.7mm SS197 out of 5 inch barrel = 355 ft. lbs (40 grains @ 2000 fps) 5.7mm SS190 out of 5 inch barrel = 320 ft. lbs (31 grains @ 2150 fps) -DmL |

I never said otherwise, nor was I by any means the first in this thread to compare the bullet weights/velocities of two different bullets, so it's funny how I was the first one to get that reply. But anyway, those who compare the two say they are similar ballistically, making no statement about tissue. In the meantime, it is the same case when the 5.7x28 and .22 WMR are compared in terms of tissue disruption.

You make a good point. Once day maybe we will get away from the notion that bullet weight has a direct effect on lethality. As for the .22 Mag. statements, they are false. The 5.7 is more effective, due to its longer length and tumbling. That said, 5.7 and .30 Carbine are both submachine gun cartridges, and do OK within certain constraints. |

Yup, F=MVsquared doesn't tell the WHOLE story... But wasn't the 5.7 specifically designed NOT to fragment? Bullets can be Armor-Piercing or Fragmenting but rarely both... So the question remains...which is more LETHAL... |
|
|
All I can say is...use BIG mags. The more rounds the merrier.
