I just noticed that Corbon has the glasers for 7.62x39: https://dakotaammo.net/shop/product_info.php?cPath=24_101&products_id=166

And frangible bullets are available: http://www.bigskysurplus.com/7.62X39.htm and http://www.frangibleammo.com/catalog/f6e166e5-4e47-43b1-abb3-88fa9e489602.aspx

I don't know what the performance of either would be like compared to 223 defense ammo on a human target. If they fragment well and don't penetrate they could take advantage of a little more energy over the 223. I would think the glasers would disperse the energy fairly well but I have never tested them.

to lazy to fully peruse thread but...

350-400 dollar ak turned over to cops vice

800-1000 m-4/ar15 variant...

As long as it's reliable, don't think accuracy is an issue at condo, apartment, or house ranges (unless you live in Versailles)
 
Booner has more rounds downrange than small armies. The man is a machine, when it comes to shooting. The naysayers would be wise to listen to him.

I've never seen him use a revolver before. I don't even think he owns one right now. Anyways, a new guy was at an ACTS match, and Booner shows him how to load his revolver quickly. I thought I was watching Jerry Miculek in action. When he shoots slugs out of a pump, it's like watching a person shoot a low recoiling AR.


I suppose this debate will never end, as long as the doubters don't read.



Oh, and the AK guys saying the AR isn't reliable is getting old too.
 
Stop, you will make me blush.

but thanks. the problem with the erroernet is that soem will listen to those that dont know

back on topic
yes frangile is nice, but it lacks certian needs. liek the ablity to penetrate heavy layers to get to vital organs and or armor which has been prevelent in many home invasions
 
"Oh, and the AK guys saying the AR isn't reliable is getting old too."

My M-4 has gone "bang" every time I shot it in Afghanistan. Used Mil-Tech & brough my own mags with Magpul springs & grey followers.

Look forward to taking a class or 2 with your outfit when I get back, Booner :D
 
Booner:

I thought that frangible may not be the best type of ammo choice. But I assume it able to disperse shock energy well, non-the-less. I do think that the Glasers, being compressed shot, should penetrate clothing quite easily at 1500ft-lbs. After all, it shouldn't have become far separated yet by clothing, but rather a somewhat solid mass at the clothing layer. For standard clothing to disperse that kind of energy, it would have to be spread over a very large surface area.

I have personally seen a low-velocity bullet that hit a steel plate return and go through a heavy nylon coat, a sweatshirt, a t-shirt, and then through a pair of thick Carhardt overalls, and then finally penetrate the skin about 1/2". It traveled through everything sideways, not straight on, and was mushroomed to about 45 caliber at less than 130grs. Seeing this, I can't agree with your outlook on clothing penetration being hindered whatsoever.

And Booner, isn't body armor only present in about 0.1% of home invasions? I guess I'm a little confused. You just brought up the issue of penetrating body armor, but otherwise argued that the 223 won't over-penetrate a human body. What ammunition type will most likely accomplish these two things successfully?

blackhawk2000:

I think by saying that you mean, "as long as someone doesn't agree with my views on the AR15".

And it's wonderful that someone you know is a shooting fanatic. However, that does not actually grant any credibility to issues so far discussed, I'm sorry to say. Most of us are probably just as capable of searching the internet for data.

Isn't it true that the AK has higher clearances built into its design? And wouldn't it be safe to assume that because of these higher clearances, it is a more reliable design by physical nature, along with its gas system? By clearances, I do not mean tolerances. I have heard before that tolerances in the AK are along the lines of what they are in the AR on military rifles. A machinist could clarify this, if this is actually incorrect.

A few manufacturers are also introducing gas-piston AR designs. Can you maybe elaborate on why they are doing this if the original AR platform is already such a reliable design?

I'm not arguing that the AK is a "better" gun. I think that the AR platform is phenominal, which is why I have had one coming together in 300SAUM long before this thread had begun. What I am really asking is why the AR qualifies as the more superior home defense weapon, rather than the more superior weapon of popularity - which are two different issues. With the AR, are you really getting $500 more worth of home defense? Or are you paying for things that would be better utilized on a range, rather than realized in the home defense scenario?

I realize that Booner posted tests which he found describing 223 performance against pistol calibers, which does point out a few interesting things. I enjoyed reading that. However, this specific thread is not based on any pistol calibers, nor does the info compare defense-type 7.62x39 ammunition against any 5.56. With that in mind, its relevance to any of this discussion is negligible.

I feel that these threads are really arguing over a different topic. A message that is not read as "which is more suitable for home defense", but rather a message read as "what do you own and feel has better cosmetic looks". It is no surprise to me in the end that the polls may not reflect a real world vote on the question at hand.

Firepower, you might post your location since that will probably affect some of the recommendations you receiver. Whose brand of M4 do you have?
 
I'm more concerned with the physical effects of the noise- temporary and permanent hearing loss.

I'll make sure I am gonna survive and then worry about my hearing. An AR15 gives me a better chance to survive and and stop any threats than a pistol...

I doubt that one situation of home defense with an AR15 will result in one being deaf for the remainder of their life...
 
Both are too loud indoors for me to consider
Unless you're talking about an SBR, the noise levels are comparable to handguns and shotguns, although the frequency spectrum is different (rifles are more "boom-y").

http://www.freehearingtest.com/hia_gunfirenoise.shtml

Not sure if these figures are straight dB or dBA.

Table 1. SHOTGUN NOISE DATA (DECIBEL AVERAGES)

.410 Bore 28" barrel.....150dB
26" barrel...............150.25dB
18 _" barrel.............156.30dB
20 Gauge 28" barrel......152.50dB
22" barrel...............154.75dB
12 Gauge 28" barrel......151.50dB
26" barrel...............156.10dB
18 _" barrel.............161.50dB

Dr. Krammer continues to say that shotgun noise averaged slightly more that 150dB. This is approximately 14dB beyond the threshold of pain, and more than sufficient to cause sudden hearing loss with complications.


Table 2. CENTERFIRE RIFLE DATA
.223, 55GR. Commercial load 18 _" barrel.....155.5dB
.243 in 22" barrel...........................155.9dB
.30-30 in 20" barrel.........................156.0dB
7mm Magnum in 20" barrel.....................157.5dB
.308 in 24" barrel...........................156.2dB
.30-06 in 24" barrel.........................158.5dB
.30-06 in 18 _" barrel.......................163.2dB
.375 — 18" barrel with muzzle brake...........170 dB

Krammer adds that sound pressure levels for the various pistols and ammunition tested yielded an average mean of 157.5 dB, which is greater than those previously shown for shotgun and rifle noise levels. There was also a greater range, from 152.4dB to 164.5dB, representing 12 dB difference, or more than 10 time as much acoustic energy for the top end of the pistol spectrum. It should be noticed that this figure of 164.5 dB approaches the practical limit of impulse noise measurement capability inherent in most modern sound level meters.


Table 3. CENTERFIRE PISTOL DATA
.25 ACP...........155.0 dB
.32 LONG..........152.4 dB
.32 ACP...........153.5 dB
.380..............157.7 dB
9mm...............159.8 dB
.38 S&W...........153.5 dB
.38 Spl...........156.3 dB
.357 Magnum.......164.3 dB
.41 Magnum........163.2 dB
.44 Spl...........155.9 dB
.45 ACP...........157.0 dB
.45 COLT..........154.7 dB

For those who don't grok decibels, it's a logarithmic scale (usually log10); a 3dB difference equals twice the radiated acoustic energy, and a 10dB difference is ten times the radiated acoustic energy. The ear perceives a 10dB difference as a doubling in volume, and IIRC the average person can just barely distinguish a 1dB difference. A car interior at highway speeds is 60-70 dB, a vacuum cleaner in the 80's to 90dB, I think.

Contrary to popular belief, there doesn't seem to be a huge difference between shotgun, pistol, and rifle noise levels, although the sound spectrum is undoubtedly different. There is a correlation with caliber (e.g., .30-06 is louder than .223 and .357 is considerably louder than 9mm or .45), but the most striking difference to me is how much louder a muzzle brake makes a hunting-caliber rifle (nearly 6 dB louder than an unbraked rifle, using an 18" .30-06 as a comparison, or translates to approximately 4 times the radiated acoustic energy). There's a tight correlation with barrel length (shorter is louder for any given caliber), but also less correlation with velocity than I expected (i.e., a slowpoke .30-30 round out of a 20" barrel is a smidgen louder than a faster but much smaller .223 round out of an 18" barrel).

For the purposes of this thread, here are some particularly relevant data:

.223, 55GR. Commercial load 18 _" barrel.....155.5dB
.30-30 in 20" barrel.........................156.0dB (7.62x39mm is comparable)
12-gauge shotgun, 18" barrel.................161.50dB
9mm..........................................159.8 dB
.357 Magnum..................................164.3 dB
.45 ACP......................................157.0 dB


Not such a big difference; if you add a few dB for 16" barreled carbines instead of 18"/20", you'll probably be somewhere between 9mm and .357 sound levels for both rifle calibers.
 
Thanks for the info benEzra.

I run a 9mm carbine for just those reasons, 127 +p+ should be comparable to a .357 mag in FPS.

I agree here too, but I would like to be able to hear while involved as well.

Not a problem, I'd say. I've made the mistake of firing off a handgun outdoors with no ear protection. It causes a ringing. Not a ringing like a telephone next to your ear - a ringing like a phone in the other room or something. You can still hear people talk, hear water running - but there's a ringing present for a while to come. Half hour, sometimes an hour. No problems hearing things, but the ringing was very annoying.

Shooting minus ear protection can cause deafness eventually - but, IME, it doesn't cause temporary deafness. Normal conversation's not a problem... as long as it occurs between shots.
 
I think by saying that you mean, "as long as someone doesn't agree with my views on the AR15".


Not at all. Everyone is entitled to their own opinions. I'm sick of shotgunners, and pistol guys coming in to every rifle for HD thread, and spouting off about over penetration, about how much easier it is to retain a pistol than a long gun, about the pants pooping sound of a SG pumping, about how hard it is to maneuver a long gun in a house, and whatever else they think is wrong with a rifle, but really isn't. Does the SG forum have these same problems with rifle guys?
 
Wow, I thought I was the only one who ignored you! :neener:

Blackhawks got it, though..Booner knows his stuff. He shoots *and* studies, and doesn't talk unless he knows what he's talking about. He's one of the most intelligent people I know..and also one of the best natural born teachers I've ever met..mostly because he's a great student.

Just takes a while for the rest of us to figure out what he's trying to say.

Then again, if they'd make a keyboard his paws would fit. :)
 
Bartholomew Roberts

I have Colt M4.
And I I have about 10 various AK types since I have about 30 guards with me most of the time. I am in the Tribal Areas of Pakistan.
 
Hey, leave my Scars alone...

as for WEG i dont recall calling you anything. there was loose term there used in one of my first post. so get over it.

as for my speling I dnt spel rel wel My mum made me clen chikens and Milk cows.........

I am by now means an expert but yes i have spent a ton of time in classes reading learing and doing

then again like being Ignored


Enjoy I have said my peace enjoy.
 
interesting ak/ar comparo vid
with penetration results 3/4 of the way thru

Interesting. I would not have guessed that the 7.62x39 is the superior penetrator to the 5.56 on hard targets.
 
I'm more concerned with the physical effects of the noise- temporary and permanent hearing loss.

Shooting without ear pro, particularly shooting inside without ear pro, is definitely a bad and just dumb idea for training.

In a real world situation, especially a home defense scenario where you're not going to be burning through multiple magazines of ammo (unless you really hang out with the wrong sort of people), it's not a big deal. The numbers seem to indicate that most people in defensive shootings experience auditory exclusion anyway, for that matter, and don't even hear their own or other weapons firing.
 
I voted for both, and by that I mean either, though I would only employ it in a Katrina type situation.

Read The Great New Orleans Gun Grab if you don't see the need.
 
So our original poster is living in the tribal areas of Pakistan and has a Colt M4 with Okay and Thermold mags that isn't running well.

Firepower, first thing I would do is ditch the Thermolds. They have a reputation for being problematic. If you can't afford to do that, then you need to mark your magazines and note which ones you have the problem with. M4s are very particular about ammunition and magazines and good examples of both will help solve a lot of problems. Both of the problems you describe are classic magazine problems.

Second, some of the advice you have gotten is based on the presumption that you were in America and living here, so I would ignore any advice that doesn't seem to fit your situation.
