300blk is suited for short barrels so if you are going with supersonic, you'll be more effective than with 556 when running similar length short barrels.
If you want to run supers, you can but frankly a super 300blk and 45ACP, both out of similar length barrels, for home defense distances, are ballistically about the same. Both will blow your eardrums out indoors unless you are suppressed. Keep that in mind. After comparing 300blk and 45ACP, using a PCC in 45ACP maybe better for home defence as you can suppress it very well (as does 300blk) but you have a lot more bullet and power options in 45ACP. My personal favorite is the CMMG Banshee as I can run regular 45ACP, 45 Super and 450SMC in it. I get the best of all things. I have both calibers though so can compare. I basically use the 45ACP, suppressed, for close stuff and use the 300blk for the 100-200 yards range, in supersonic, as that's all my local landscape will be offering for shots anyways and its more effective than 556 in that range due to energy and bullet options. I like suppressed all the time for all things too and suggest that to everyone. |

I feel that the consensus is still that 10.5 5.56 is perfectly adequate for < 50yard encounters. I haven't tried one, but I wonder if a linear comp would help indoors at all? Noise is no doubt a problem, but I keep a set of howard leights next to my rifle just in case I have time to put them on.

Nothing inadequate about a 10.5” 5.56/223 at home defense ranges. Especially if you shoot expanding bullets like the Gold Dots or Fusions, which you should.
Any short barrel AR needs a suppressor, imo. |

OP, you can get a YHM Turbo suppressor w/ stamp or something like that for about the same cost as a brand new low-end 300blk upper, and that's not even factoring in the new ammo ($$$ these days) you'd have to buy to feed the 300. I have multiple 5.56 guns and a 300blk, and if I were in your shoes. I'd 100% get a suppressor for my 10.5" 5.56 before I bought a new 300blk upper. Also, a suppressed 5.56 will still be orders of magnitude quieter than an unsuppressed 300blk. All that said, a suppressed 300blk is my bedside gun and I do like the round. Get both? |

I have a 300 BO with a suppressor for this purpose, and I'm glad I do.
But before I got all that put together. Here was my solution:  Attached FileI bought an extra two pair of electronic muffs , one for me and one for my wife. I hung them on the wall just above where the weapons are stored. It takes just a moment to put them on. And if I have time, I can turn the power on and have enhanced hearing while clearing the house. I spent less than $90. |

I have an 11.5" suppressed BCM and an 8.3" suppressed 300blk.

As others said you are better off getting a suppressor than a 300 black given the cost of both and you'd still need to suppressor the 300 anyway.
I think 10.5 is fine in 556 for 100 yards and in. Given subsonic 300 black is basically the same as .45 I'd argue a preference for a pistol which puts you in between super 556 or 300 and 300 is better but 556 is great and again both are super loud. Also it sounds like you are on a budget and unless you cast your own lead subs 556 is cheaper to shoot generally by a lot. |

If you're worried about noise get a can if you can. If not, a blast can like the surefire warden helps some. A 10.5" 556 stomps subsonic 300blk in just about every category. With supers the 300blk beats the 556, but the difference in performance is not huge. 300blk supers are only marginally better than 556, and the best 556 rounds like, 77gr TMK, actually perform better than many 300blk rounds on soft targets. Also, without a can 300blk supers are just as loud as 556 so its a tossup. I'd say stick with what you have, no need to get into 300blk now with ammo availability being what it is. aLike others have said, you can buy a "budget" can for the price of an entry level 300blk upper, so thats what I'd do if you can

With that said, both will get the job done, and both will be loud as hell indoors. .300blk will have less flash/blast/gas and more energy...and "slightly" less noise. I dropped my 10.5" 5.56 my (originally 8.5" .300blk) 9" .300blk. But I'm pretty sure that my 10.5" 5.56 with 77gr SMK would have worked just fine for HD. .300blk ammo prices SSSSSSSSSSSSSSSUCK!!!!!!!!! |

Thanks everyone for taking the time to help. I guess I've been reading a lot of inaccurate forum posts from various places. A big majority of people are poo-pooing my 10.5" 556 for home defense. Certainly I'd prefer to keep what I have rather than buying another upper and the cost of getting it outfitted correctly. I was not big on the idea of adding another caliber to my collection with the 300blk already. I was definitely considering the supersonic loadings in the 300blk, particularly the 110gr Vmax. But if the noise level of a supersonic 300 is about the same as a 556, then it's really a wash for me then. I'd prefer to just stick to the 556 caliber that I'm already running. I do reload, but I can still see how the 300blk would cost more to shoot than the 556.
It looks like I need to be researching suppressors a little more then and forget about the 300 maybe? |

I use a 10" 5.56 for home defense. I keep a suppressor on it and use good ammo.
Look at TSX, Fusion or Gold Dot loads. 75gr T2 and 77gr TMK is also a good option. |

Much good input in this thread from many people. I still think that 556, in short barrel format, in tight spaces, is not ideal. There are better options to focus energy on the target and mitigate ear and eye damage to the defenders. 300blk super is good and 45ACP with a barrel longer than a handgun is also good. Any bullet you use should be able to expand at expected velocities at the range your target will be and minimize travel into other areas where innocents may be. |

Yes.
Supers with suppressor and boutique Lehigh 115 grain. Fucks shit up like a mofo. Noise is quite tolerable. It will make your ears ring for sure. But nothing like cutting loose a .308 SBR in your bathroom.  Attached File |

Suppressed 5.56 SBR is good too. But doesn’t provide option of shooting subs if you like the idea of .30 caliber subs.
Lehigh makes an excellent .30 caliber bullet for subs. But you give up the permanent wound cavity with subs. Realistically, anything inside the 8-ring will put the receiver out of the fight. Even .177 BB if you collapse a lung. |

The ammo type matters more than 10.5" vs 11.5" for self defense.
A silencer matters more than 300 BLK vs. 5.56x45. 300 BLK has a big disadvantage in ammo cost and availability. It is inherently less accurate and has less effective range. The advantage is under 150y shooting barrier blind ammo, the ability to shoot subs that cycle the action, and the ability to run a barrel under 10.5" with good reliability. If you don't need those, don't get a 300 BLK upper. It is NOT quiet at 11.5" and under barrels without a can. |

Ok, I’m going to offer my “opinion”, and would expect that some may disagree. I have used both a 12.5” 5.56 and a 9” 300 Blk as my home defense guns at one time or another and neither of them now serve this purpose. As far as 5.56 is concerned, I don’t even own anything with a barrel less than 16” anymore. I’m not building clone rifles, I’m not kitted up in a vehicle, and I don’t like giving up the velocity that makes that caliber lethal on two-legged animals. Of course, for home defense I employed a suppressor, but the same problem that makes a short barreled 5.56 so loud (burning a lot of powder outside the barrel) is also a problem when running a suppressor. Anyone who has ever run a short barreled 5.56 with a can has learned how to take a big deep breath of combustion gases and charge on with a teary eyed smile. So I swapped over to the 300 Blk, except that the same thing that makes that bullet “barrier blind” will cause serious over-penetration issues in a residential setting. Granted the 300 Blk was designed to burn all of its powder in a short barrel so even the supersonic loads aren’t anywhere near as loud as a short barreled 5.56, but the over penetration risk made it a no go for me. So where did that leave me in my quest for a home defense gun? I went back to the basics. There’s nothing that will stop a fight like a 12 gauge shotgun; I’m not quoting Clint Smith, but you get the picture. I’m not preparing for hordes of zombies, so I’m betting that my Remington 870 with seven rounds of #4 buck will take care of any trouble that finds me.

Quoted: I've been reading and reading and reading and at this point I think I'm kind of in information overload. Currently, I have a 10.5" AR in 5.56 for my dedicated home defense rifle. After reading a lot of people talk about the diminished ballistics in the 10.5" but more importantly the kind of hearing damage that can occur when firing the 5.56 from a 10.5" barrel inside the confines of a home, I'm kind of rethinking my decision. I know, I know, I've read all the comments about better to have some hearing loss than be dead. I'm just thinking is there a better option than 5.56? Would a 10.5" 300 Blackout maybe be a better choice? I know there is the suppressor option and I'm not ruling that out for a future purchase. But with funds being tight, would a 300 Blackout upper be a better choice in the meantime? And a side note, I remember back when all the forum "experts" said that the 10.5" was the minimum barrel length to be effective when chambered in 5.56. But now the consensus seems to be that the 10.5" is too short and now the minimum barrel length should be at least 11.5" in 5.56 with 14.5" being preferred. I think I may still hang on to my 10.5" 5.56 upper, but wondering if there is a better cartridge to use for short rifles in a home defense situation.

Since I can't have a can in Illinois, I quickly learned that my unsuppressed 10.5" 5.56 wasn't going to cut it. My first trip to an indoor range cured me of that foolishness. With that said, I do agree to an extent in terms of dumping velocity on a caliber that is dependent upon velocity. I dumped my 10.5" 5.56.....and I recently mothballed my 12.5" 5.56 (which wasn't bad...it was just down to a 12.5" or a 16" in 5.56. They were going to be set up the exact same way). For anything up close (HD/SD/PDW range), .300blk was the way to go .

My main home defense weapon is a 10.5" 300 BO pistol with a 7" ThunderBeast suppressor shooting THESE- bullets that are designed to expand at subsonic velocities. I handload these bullets to subsonic velocities resulting in 'mouse fart' noise with the knowledge that it'll get the job done if needed and minimal worry about overpenetration. They also offer a 'fracturing' version of the same bullet that is even safer from overpenetration.
This same company offers these bullets already loaded as subsonic ammo for those that don't roll their own. Something to consider................................. Bird |

I honestly don't recall ever using up all my HD ammo, because I rarely have to unleash any inside my home. SBR or Pistol w/ 300 subs in 8-10.5 will be just fine for HD, might put on a linear comp + blast can to help keep some db's off the ears, but as mentioned already, it will all be loud because as we all know, sound bounces off walls and stuff like a 10c superball. True dedicated HD, then 300sub w/ suppressor on 8" will be as good as it gets, + less copper coated lead being found in homes a block away. That said, not sure what the draw is to use AR15 in the home, I have various pistols for that task. To each their own I guess. |

For some, obtaining pistol may be difficult, in those cases I often recommend semi-auto 12 or 20ga shotgun w/ bird shot. Certainly it's a personal choice. I don't think anyone is deploying flash bangs in their own house....you might need the fire department more than the police. I do think modern pistols with good ammo will work fine for HD. A full size handgun with good ammo, a light/laser and an MRD is a hell of a lot better than a sharp stick and angry words. But I don't think a handgun beats the security and accuracy of 3 touchpoints plus a sling....along with the additional firepower and range (if you hear something outside....like someone possibly breaking into your shed). I do agree that it is a personal choice. It probably depends on the situation and what weapon is closer for me (EDC or .300blk). |

Just be honest with yourself about who is more likely to be forcing their way into your home. According to the new administration, we have a tremendous population of "Domestic Terrorists". Current and former LE and military were explicitly referenced.

And with this new stat it's more evidence we all need to build build build and buy buy buy more. Gotta be prepared for these "domestic terrorists" who are not only "criminals" but also "highly skilled" too. |

So when LE uses flash bangs you are saying they are risking burning down the whole structure, possibly killing innocent others along the way? Geez, perhaps that item should be banned from use by LE? LE won't even use water cannon to control BLM, something is very wrong with LE strategy and tactics these days. But hey, now that LE are on the edge of only being able to carry a taser, not really sure what's the purpose of LE these days. NYC subways have massive amounts of serious crimes going on now, pushing onto tracks, beatings, slashings, etc. NYPD are in each case no where to be found. The good folks in NYC need to start carrying per COTUS 2A, and popping thugs the Goetz way.

I thought another point to consider was feed reliability? Always read a 300 blackout in short barrel feeds more dependably than the 5.56? Can anyone chime in here? Very interested in this thread.

Very interested in this thread. I wouldn't say that. I will say that fat subs feed much better out of 300blk specific mags due to the smaller side ribs. |

Quote HistoryQuoted: 300blk is suited for short barrels This is a myth btw. The longer the barrel, the more velocity, the more energy the round carries. Applies to 308, 5.56, and even 300AAC Blackout. A shooter can get MUCH better ballistic properties (Velocity/Energy) shooting 300 from a 16" barrel. |

A shooter can get MUCH better ballistic properties (Velocity/Energy) shooting 300 from a 16" barrel. You're missing the point, nobody is arguing that longer barrels don't give better ballistics. Not everyone wants to swing a full size rifle through the door, especially if using a can. 300blk just gives much more energy out of shorter barrels than 5.56. 300blk (110gr supers) give roughly the same energy from a 10" barrel that M193 gets out of a 16" barrel. So yes, it is MORE suited to short barrels than 5.56.  Attached File |

The pervasive incorrect talking point is that 300AAC is designed for and best utilized with short barrels.
The person I replied to wasn't comparing 300AAC to 556, he was repeating the above and added it's better than 556 from short barrels. That's not the same thing and it's half correct, half incorrect. First, 300AAC is best suited in longer barrels, and second, 300AAC will of course deliver more energy on impact than 556 as long as it keeps it's velocity. It's over twice the mass... this should be obvious. While its definitely true that 300AAC knocks the pants off 556 inside 300 meters, that effectiveness advantage is NOT due to barrel length and it's NOT true that 300AAC is suited for shorter barrels . Just trying to keep the info correct here for ole OP in case he wants to deliver the most ft/lbs of energy he can while using 300AAC while also protecting him from the false notion that AlL tHe PoWdEr Is BuRnT aFtEr NiNe InChEs. |

If I were in your situation I would keep the 10.5 5.56 and get a can before getting into .300 BLK. I would also suggest you get a 30 cal. can. It will work fine on 5.56 and if you get a 300 BLK
in the future you'll already have the can for it. |

Quote HistoryQuoted: Thanks everyone for taking the time to help. I guess I've been reading a lot of inaccurate forum posts from various places. A big majority of people are poo-pooing my 10.5" 556 for home defense. Certainly I'd prefer to keep what I have rather than buying another upper and the cost of getting it outfitted correctly. I was not big on the idea of adding another caliber to my collection with the 300blk already. I was definitely considering the supersonic loadings in the 300blk, particularly the 110gr Vmax. But if the noise level of a supersonic 300 is about the same as a 556, then it's really a wash for me then. I'd prefer to just stick to the 556 caliber that I'm already running. I do reload, but I can still see how the 300blk would cost more to shoot than the 556. It looks like I need to be researching suppressors a little more then and forget about the 300 maybe? Just keep in mind the cost of actually using your rifle with a can and then potentially not getting it back. Expensive, but you also can't un-blast your ears, so... A lot of people arguing gun stuff on the internet are like kids in the 80's arguing over whether their dad could beat up Hulk Hogan. They're kind of full of it. I would personally pick a 11.5" over 10.anything in 5.56, but I wouldn't get rid of something I already had; it's not worth the cost of ammo to rezero. Your AR will get the job done. If you have to consider the cost of ammo at all, then .300 is still too expensive to shoot regularly. This would have not been the case if the riot/pandemic/election panics had not happened and .300 steel case had finally hit the market at low prices. |
