robin6512: @TheAK47nut i'll go for the 7.62 too but i wouldn't try to catch the .223
1lostinspace: lol 5.56 is nasty!! It tumbles and frags it has to be going 2800 fps
Tuxedo413: How far do you think it goes in before it starts to yaw or fragment?
drchen054: hard to say im not a gun expert but I suspect the 5.56 has a flatter
trajectory up to 800 yards but after that, a heavier bullet like the 7.62
would be more accurate with single burst.
f8talh8red: wheres part 12???
dadajack yo: but firing at a distance over 500 yards, which bullet has the better chance
of actually hitting the target?
dadajack yo: People love to hate on the 5.56 cause they heard it goes right through
skinny people. Guess what, the 7.62 does also. The difference, in inches,
between a 7.63 and 5.56 is .075". The energy difference between 7.62x39 and
5.56 is 200ft/lb. I know you have to pick one as your favorite, and mine is
5.56 for SD/HD and 7.62x39 for plinking or hunting. Plus, 5.56 is much more
accurate in my own personal experience. I like a flatter shooting round.
bazookajoethethird: @ericvandermolen and the 5.56 has the "tumbling" effect
BWT68: @SacTownStudios Exactly, the bullet structure fails mid yaw and comes
apart. Which is what it was designed to do. Hornady 75 gr 5.56x45 TAP (Not
.223 REM) can fragment out to 160-180 yards out of I believe a 16'' barrel.
It fragments out to a hundred out of a 10-ish inch barrel. Which is again
optimal. I mean don't get me wrong, I pickup my SGL21-71 tomorrow at my
FFL's. But 5.56x45mm would be great for home defense, etc. 7.62x39mm FMJ
will punch through walls/cars, etc which is good and bad.
Nick Varnadore: Do a 77gr 5.56 round
SweStuff94: @TheAK47nut dosent it waw bc of the round being back heavy and bc of the
refeling of the gun? sry 4 my english :)
girlmalibu1: All in all the .223 is a nasty round and I bet no one wants to get hit by
Bobby Johnson: This round is awesome
1337ASM: @TheAK47nut And, from a logistical stand point, the 7.62x39 is great, since
it is used in the most popular weapon in the world.
69mrkfc: tie the block down
Airen Farmer: The rifiling of the barrel, and velocity of the bullet causes the
trajectory to change direction in flesh and ballistic gel. but yea that gel
is pretty clear.
dadajack yo: I suppose I should have quantified the question by mentioning the
platforms. The difference between the 7.62 and 5.56 in my experience would
suggest I have a much greater chance of landing a round on target with a
5.56. Now, compare a 5.56 with a .308, I'll take the .308 for down rage
energy with the possibility of being as accurate with the available
drchen054: depending on the distance right? 5.56 at over 500 yards isn't going to
TheAK47nut: I think the 762 wins after seeing it up close and personal!!
sotik: Guys when you have a exits hole in the front gel on the top, and a entrance
hole in the second gel on the top. This means that the problem lies in the
gel blocks moving while the bullet is traveling through them. It has
nothing to do with the bullet. Either weigh those things down or strap them
NastyChuck: @TheAK47nut How long was the barrel that the 5.56 was shot out of?
Ignacio Mendez: Suggestion, please upload a 5.45x39 ballistic gel video, and also would
like to comment. I personally believe that the 5.56(223) is a far more
lethal round then the 7.62x39; you got fragmentation of the round, you got
precision, you got more bullets to carry with you(in combat). Not only does
it fragment, but it fragments at the right time, where the organs would
be(given the right placement of the shot.)
FJones9508: Sac almost hit it on the head. The bullet is so light and traveling so fast
that the front tries to slow down and the back keeps trying to go fast.
Back in the day when the M16 had 1 in 11 rifling the yaw used to be so bad
that it would take peoples arms off and cleave the top of a head off.
Hollow points in .223 can be quite devastating also.
DARTHxPOOH: There is no such thing like "Stopping power"
dxxa94: @TheAK47nut yea AK-47 RULES but 5.56 hav 2 frags and AK hav more power and
PatandNicole: These guys don't realize there gel is not a consistent blend
GTILOUD: @ignaciom184 Both have 30 rd mags, 5.56 would weigh less by what 3 ounces?
Same amount of ammo though, there are 7.62x39 ammo that reliably fragments.
I can't argue that after 300 meters the 5.56 is more accurate, however if I
am shooting something 300+ meters away in self defense I have bigger
problems. The 7.62 ammo is wayy cheaper for hunting or shooting for fun
even hp sp ammo is significantly cheaper than lc 5.56 just by a Arsenal ak
to support U.S economy.
Bari Servello: I can fix the problem. the gel is moving as the goes in. just place types
bricks on top of the gel and it will go straight.
andrew coleman: You must have been standing when you took the shot. Firing into the block
from a postion higher than the block itself will cause a "rock skipping"
Jack Attack: Thanks very much for posting this online, it is a great resource for people
trying to learn about the performance of various calibers and loads. I will
use it to teach some friends about ballistics when I give them a basic
rifle class later. Take care.
Infiniti350gt: Amazing to see how much a .223 or 5.56 really tumbles and turns in a
target. I've noticed in the past that longer distances are easier to test
like this because you see the real damaging effect of the 5.56 when it
moves around a lot more. Up close I've had the same things happen ripping
through the gel or just not yielding the results I was looking for. Nice
Angel Fernandez: you guys need to put some weight on that gel so it does not flip up and
cause the round to come out.
EZ2anger: I think both are almost a guaranteed one shot stop, it's just a matter of
situation or preference. The 7.62 will penetrate most kinds of cover and
armor, but it has to rely more on hydrostatic shock to kill, whereas the
5.56 relies more on tissue damage and is less likely to exit a target.
ericvandermolen: I think the .223 will do a lot more internal damage because of the
fragmenting it does (though this vid doesn't fragment), but the 7.62 has
more stopping power. If you want to knock someone down on the first shot, I
would go with the 7.62. Don't know if you saw the 7.62 hp vid that this guy
has up, but the ballistics gel gets pushed back so far with that bullet.
TheAK47nut: @robin6512 Ooh come on if you use your teeth youll be fine!! ;-)
youDISTURBEDme14: the 7.62 has more power and force than the 5.56 but if you shoot a 7.62 fmj
it will likely go straight through them. on the other hand, the 5.56
travels much faster than the 7.62 and fragments causing internal organs to
turn into jelly. there aren't very many people who have survived a 5.56
gunshot but many people have survived 7.62 wounds because the 7.62 fmj wont
tear apart like the 5.56. 7.62 soft points are a whole different story.
those will beat any 5.56 bullet any day of the week.
dxxa94: Yes the 5.56 nato hav 2 fragments
SacTownStudios: What people need to understand is that the 5.56 is fast and small so it
doesn't have a lot of punch to it. It's the yawing and/or fragmentation of
the round that makes it effective because the tumbling/explosion of the
round causes more damage than if it went straight through. And what makes
the round tumble is the fact that the bullet is traveling so fast that the
lighter front end wants to stop but the heavier back end wants to keep
going (do to momentum) causing instability and yawing.
MachoCamachoZ: @sotik I spotted this too, especially in the 9th or 10th video. You can see
the front curl up.
UncleFexxer: It's not the nature of the round, it's the nature of your blocks flopping
around under impact.
john h: The reason the 223 is "yawing" is most likely do to rifling twist ratio and
