I use a shotgun and pistol for my home defense, not my AR or AK, nor do I
use my Deer rifles. When I have people in the house with me I go with lower
velocity hollow points. If you want a large capacity weapon their are some
fantastic Sub guns on the market

Are you in California

Everyone shoots through denim… that’s so outdated. Criminals and thugs
quit wearing jean jackets in the 80’s!

sam torr · September 23, 2014 at 12:09 PM

why does the velocity increase with barrel length? I would of thought the
longer the barrel the more friction the round experiences, so the less the
velocity, i would of thought. 

Devgru77 · September 23, 2014 at 1:04 PM

Correct me if I’m wrong, but are these bullets lead core? Have you done any
testing on PPU or PMC?

zeroxwolfx · September 23, 2014 at 1:58 PM

Makes me feel better about ordering this, except mines a 1:7 twist… hope
it doesn’t hurt performance too much.

Shamrockrancher · September 23, 2014 at 2:51 PM

This is an excellent video, as are all your others. I appreciate the effort
and work you put into these. Thank you.
The way that gel block wiggled, shook and rolled reminded me of my fat ass
when I’m running for my second plate of pancakes on Sunday mornings.

Reading through the comments… some are good and some, not so much. If
you’re gonna use a 5.56, 7.62, 9mm, 45 acp, whatever it may be, you have to
simply know what you’re shooting at and what lies beyond the target (cliche
but not that simple when your heart is pounding and your family’s ass is on
the line.) If tragedy strikes, have a plan for your children and loved ones
(mine do, and they are 2 and 7) so it can be done. But, you have to be
smart about it (that doesn’t mean hesitation, that means situational
awareness.) Train yourself, train your loved ones (btw: Martial Arts goes
hand in hand in the real world.). Always be ready, practice, train, educate
(and educate yourself), train more, drill more, train more, and realize…
once bullets leave the barrel, they’re not coming back… and vice-verse.
Penetration is going to happen (no pun intended) regardless of caliber, so
be prepared for the worst. The goal is to protect your loved ones, period.
Great video. Thank you Sir.

Avi Elkovits · September 23, 2014 at 4:31 PM

No I don’t plan on testing it through 4 or 5 walls, that would be a really
bad scenario and I hope that doesn’t happen to anybody. Ya, that is the
point! As a gun owner I am furious that all these people on youtube are so
happy to recommend the 5.56 as a home defense round. Without fear for the
neighbors, family members, or others who may be behind 4 walls that will be
cleanly penetrated without massive fragmentation, or breakage. RIFLE
ROUNDS ARE NOT FOR HOME DEFENSE should be the title of this and every video
talking about 5.56 or .308 or 7.62×39 or any rifle round! 

Ki11bot · September 23, 2014 at 4:33 PM

My greatest concern is pass-through. Its the main reason I use light and
fast 9mm JHP for personal and home protection. Kids, pets, neighbors,
etc….
I like something I know is gonna punch hard and dump into the target.

Over penetration didn’t seem to happen here….which suprised me since this
round has a reputation for it.

Is this a factor? Am I skipping over a viable alternative?

Donald Frederick · September 23, 2014 at 4:54 PM

Instead of drywall, would you place a AR500 plate up against the ballistic
gel. Would like to see the results of the pass through of the m193 

Tommy Sands · September 23, 2014 at 5:19 PM

LOL step up to a mans caliber!

OrangeDiamond Barbarossa · September 23, 2014 at 5:45 PM

I can appreciate the tests you ran, but why in the hell are you running
anything “BushMaster” produces, and using a 1:9 twist barrel? Both are
garbage.

valya fadlon · September 23, 2014 at 6:18 PM

an AR is def not a home defense weapon

Shane Gill · September 23, 2014 at 6:55 PM

+tnoutdoors9 that’s not truly government surplus, it’s ammo that doesn’t
quite meet milspec, but is still serviceable ammo.

Did the cases have a LC headstamp or Federal? It bugs me a little bit that
the packaging says Federal on it. Federal didn’t make that ammo! When we
fill commercial orders, all the packaging already has Federal on it! I bet
they don’t even take the stretch wrap off of the pallets before they ship
it to distributors. Hell, we might even be shipping directly to
distributors from Lake City!

brainplay · September 23, 2014 at 7:05 PM

Placing the targets right up on the drywall is a bad idea. The drywall
will cause the bullet to start yawing and losing energy quickly. On impact
the bullet may be completely sideways thereby reducing penetration and
increasing the chances of a person surviving a stray round. However, if
the target is pressed against the wall then the bullet will have little
chance to yaw at all and will have minimal differences compared to shooting
at something with no barrier.

The takeaway lesson: It’ll kill your kids in the next room. The AR-15
carbine can be a decent home defense weapon in some homes, but not if
you’ve got a house full of kids.

I’ve chopped down trees with a 12-gauge loaded with 2 3/4″ target loads.
At “in home” ranges they are devastating, but far less lethal on the other
side of a wall than any AR-15 load.

My “defense guns” are a .380 auto for carry (because I’ll actually CARRY it
and not leave it locked up at home), a Remington 870 with target loads for
home defense, and an AR-15 for “the gubmint.” (And jackrabbits.)

Shane Gill · September 23, 2014 at 8:57 PM

+dabNtx [EDIT: I’ve done the math and there is no way that the penetrators
were tungsten. It seems that whoever it was that told me that was wrong!!!]
The M855 penetrator core isn’t made of steel, it is Carbide-coated
Tungsten. You cannot dent them with a 3-pound mini-sledge, I have tried.

Robert Bowen · September 23, 2014 at 9:53 PM

I really appreciate your informational videos. Keep up the good work

InfraRedNeck · September 23, 2014 at 10:50 PM

The drywall needed wallpaper. A nice floral pattern. 

mojo jojo · September 23, 2014 at 11:11 PM

one of these days Im gonna gel test my guns, my right arm in particular. I
have fists of steel. I wonder what kind of permanent wound cavity my right
hook will make…I have to be careful though, its barrier blind and will go
through walls and may accidentally punch one of my kids square in the mouth

Robert Dumont · September 24, 2014 at 12:10 AM

I don’t see how people can say that the 5.56 doesn’t have enough knock
down. Looks like enough to put a hurt on someone to me.

taylor wabel · September 24, 2014 at 1:08 AM

You’re using a FMJ round which is designed for penetration. If you’re using
this demonstration as an example for home defense then a hollow point round
would be the optimal round. More damage and knock down power. The last
thing you wanna do is blow through three or four walls and hit some poor
bastard on the street or even worse one of your own family members that you
are trying to protect. I am not being a keyboard warrior just supplying
food for thought. Good video though, thanks.

Until you get as good as this guy, you can cheat by going clockwise around
the inside first for a roadmap of your second cut around the outside
