Do you have a link to the fbi study?The only 556 in that test is FMJ, the fbi tested ballistic tips which only went through 1 or 2 sheets before they were fragmented and wouldn’t penetrate.

Searched for a while and only link I found is now a 404 error. While searching, I did find garand thumb did a video on penetration and confirms what I remember from the FBi study.Do you have a link to the fbi study?
I presume it is a suppressed SBR. Is it a 300 blackout gun or something more powerful like a 308? If so, which? The DDM4 V7P seems great, but possibly the barrel is too long at 10.3”? What suppressor, short or long?
For attachments, I would prefer an EXPS3-0, Cloud Rein 3.0, flip up irons, and a VFG. That’s all I think it would need as this would be used as a room clearing and short engagement distance gun.
Price doesn’t matter.
I wonder how effective a system where you (after putting on hearing protection) have a strobe system throughout the entire house and play an ear piercing 160db noise repeatedly.
Yavapai County Sheriff's Office (Phoenix area) ran a very detailed test on overpenetration in dry wall/stud walls several years ago. They tested 5.56 FMJ and non FMJ, plus a couple of loads each from 9mm handgun, 40 cal. handgun, and maybe a subgun and shotgun. Not sure as it has been a few years.I have watched a few videos now, and the 223 varmint ammo penetrates less than 9mm fmj or jhp. My personal experience, I've seen 9mm/45 acp go through apartment complexes until they hit exterior walls(about 50 feet). It isn't pretty when drug deals go bad in apartment complexes. Varmint ammo is safer than 9mm/45acp. However, fmj goes through about the same as the handgun ammo in the videos I've watched. Now that my interest has been piqued, I'll do a test comparing 223, 12 and 9 ammo on drywall.
Oh yeah. The *other* standoff device.Two F-15s on alert at the end of the hallway; F16s on holidays and weekends. F35s for special occasions.
Then there’s the orbital platforms for standoff threats.

For that bolt part, is the logic that the bullet must be moving fast enough to expand, and that longer barrel is also good to go?Yavapai County Sheriff's Office (Phoenix area) ran a very detailed test on overpenetration in dry wall/stud walls several years ago. They tested 5.56 FMJ and non FMJ, plus a couple of loads each from 9mm handgun, 40 cal. handgun, and maybe a subgun and shotgun. Not sure as it has been a few years.
Anyway. the test procedures and number of rounds fired had some statistical relevance.
Conclusion was that the 5.56 with expanding rounds out of at least a 14.5" barrel was the safest bet for limiting penetration.
This test was printed as an article in Tactical Edge magazine and at least parts of it reprinted later in at least one off the shelf gun magazine.
If you can find it, there may be info worth reading.
.
not the quoted person, but yes, expanders of all varieties require minimum velocities to deform and shed energy via the resulting fragmentation and tumbling. different constructions require different minimum velocitiesFor that bolt part, is the logic that the bullet must be moving fast enough to expand, and that longer barrel is also good to go?
Quitter.Damn, I was going to quote some things and correct the record, but this thing is such a dumpster fire I am just going to tap out.
Bye.

WAIT! You didn't color-coordinate and you didn't mount your suppressor!Here is the ultimate home defense rifle you want to copy.
You don’t need to suppress a .50 BMG. The rounds are naturally suppressed. It sounds like an airgun.WAIT! You didn't color-coordinate and you didn't mount your suppressor!![]()
you didn’t make mention of the ultimate CQ weapon.First, you need a short-barreled CQ rifle.
Second, you need a HEIAP round for home defense. Something that will penetrate multiple assailants wearing Level IV body armor. My preferred HD round is MK211 “Raufoss.” (One shot, many kills. This takes practice.)
Third, you need some kind of LRF with Applied Ballistics to compensate for bullet drop and wind deflection indoors.
Fourth, you need a scope with a large zoom range, like a 6-36x or maybe even 8-40. Tangos can be anywhere in your house by the time you awaken to the sound of a door being breached and however long it takes you to kit-up. I recommend full body armor and NODs.
Lastly, you need some kind of IR laser/illuminator and thermal clipon so you can remain undercover of darkness. You need to “own the night” in your own home and use your strategic and tactical advantages to defeat those meth head scumbags intent on ass raping you and selling your family into international slavery to fund their fiendish addiction.
Here is the ultimate home defense rifle you want to copy.

I am going to give you a serious answer. In an urban area, I would want something that isn't too big or too loud. I also would not want overpenetration. I go back and forth between a 300 Blackout subs or some kind of PCC. Having messed with them all a little, I am leaning towards the PCC. My two favorites are the HK SP5 suppressed and the B&T APC45 also suppressed.I presume it is a suppressed SBR. Is it a 300 blackout gun or something more powerful like a 308? If so, which?

I would figure that the roller delayed action would give you less "port pop". Honestly I would love a little JP JP5 SBR to run a can on.I am going to give you a serious answer.

I own the SP5 and have the Huxwurx Cash 9 can on it, I got a tri lug adapter from their site and it works like a dream. It is soft shooting, extremely easy to handle, very accurate. One of my friends has the APC45 with a Gemtech can on it. There is a little more thump to it compared to the SP5 but when you shoot .45 subs out of it, it is such a pleasure. I like it so much that I talked to my local gun store about ordering one, I prefer the version with the B&T mags over the version with Glock mags.
