Howdy, guys and gals! My name is Kyle Broderick. Welcome to The Social
Regressive. We have done sound tests in the past where we wanted to hear what
incoming rounds would actually sound like shot through a silenced rifle so we
have this this AR right here with a yhm silencer on it and we tested first some
223 rounds at various ranges everything from I think 25 yards out to 600 yards
to hear what that sounded like to see if maybe the the sound of the rifle would
disappear at a certain point and depending on the terrain and conditions
yeah actually sometimes we kind of lost the sound of the rifle itself the bullet
always made that supersonic crack so there's always a really loud sound and
we did the the same test with 6.5 Creedmoor right here and we've done some
different tests with the CCI subsonics that you see right here these are a 40
grain bullet moving out at about 1,050 feet per second so these are subsonic
Stephen from the muzzle and yes they are very very quiet but one of the
interesting things that we found is that as we started to step things back to
about 75 yards a hundred yards and then even further out we found that Hollywood
pew sound that people thought was a myth that sound actually does exist it
probably was recorded by a Foley artist and people have just been misusing it in
the movies to you know trying to make it seem like that's the sound of a
suppressed 9-millimeter at 5 feet or something and no it seems like that's
when a bullet starts to really slow down at some of the longer ranges one of the
biggest requests that I've had is to try a subsonic 223 and you know how is
that actually different from a subsonic 22 well for one thing we're gonna get a
heavier bullet there's going to be more mass behind it and it's going to be a
slicker bullet so the sound could possibly be different we're gonna find
out today thanks a bunch to my patrons of the destructive arts for helping to
make tests like this possible it's you guys that allow me to you know pick up
some of the goodies that we're using this round right here uses 5.3 grains
Hodgdon trail boss and this is using that same bullet that I use in the
supersonic test a 75 grain boat tail hollow point very slick very efficient I
think this has a ballistic coefficient of 0.4 if I remember correctly so this
is definitely going to bring a lot more heat than this and it is going to be
moving out a little bit faster this moves out at 1080 feet per second rather
than the 1050 that you get with these subsonic HP's right here and these are
this is really good ammunition by the way I'm going to break this out into
another video at some point so again thank you patrons to the destructive
arts Thank You Denver Lovelace especially he's my 300 Win Mag patron
but let's go find out what this sounds like let's get out on the range yeah you
have to manually rack at each time
oh nice yeah they did in the jab yeah no it won't you wanted to warm out it won't
oh yeah there we go
that sounded weird got it
come in a little low a little low I think so
oh yeah where were you aiming nice it has a hit
so funny I have plenty of time to roll focused those things are so slow so
how's everybody feeling so hot there you go that's a rising this is a low about
three inches
it was it bottom corner
one more
it's
get it it's so really yeah Wow
I think I think she hit it whatever it was solid
okay now Jesse I want you to explain to all the the folks out there how much of
a pacifist you are and then explain your pants yes I see deer I eat and I kill
and to explain the pants that'll explain
natural pretty interesting we found that Hollywood pew sound again now this time
it seems to be kind of kicking in when the rifle is a little bit further back
than with the 22s with the 22s I could start hearing the sound at about 75
yards and then back by a hundred fifty yards it was very pronounced with this
223 subsonic it seems to be kind of kicking in a little bit further back and
getting a bit more noticeable at further ranges in the 22 and this could just
have to do with it seems to be a product of a certain speed of the bullet it
needs to be moving pretty slow to get this sound with the 223 here we have a
little bit of extra muzzle velocity and it is a more efficient projectile so
it's not going to be moving as slow as that 22 at various ranges it's just
gonna be a lot slicker but yeah we're gonna continue testing with this we're
gonna do some 6.5 Creedmoor subsonics and we're gonna hear what those sound
like I'm kind of curious to know if it is you know at a certain velocity that
that pew starts to appear maybe if it's something to do with the shape of the
projectile because you know this is a hollow point this is kind of a hollow
point then it's a bt HP it's a you know pretty small aperture but I am kind of
curious to figure out where that sound is coming from now let's talk real quick
about purpose and about performance a subsonic 22 this is going to be pretty
effective at short range on small game why in the world would you want to make
a 223 subsonic it seems like it's kind of a waste of a lot of case capacity and
a lot of the potential performance you could get out of this and I do see this
as being functional things something that could
be pretty useful actually especially if you have a rifle like the Mossberg MVP
or something else that's magazine-fed and especially bolt-action it was kind
of annoying to fire these 223 subsonics out of an AR because every single time
we have to you know rack things again to kick out the empty there's just not
enough enough powder not enough blast coming back to actually move that bolt
carrier backward and kick out the round everything just stays locked up so it's
very manual and it kind of makes the the rifle loud because you know you have to
jack everything back and you either let it go and make it really loud or you
have to use the forward assist it's kind of annoying but if you do have a
bolt-action rifle I think it's probably a kind of neat idea especially if you
have a survival rifle so you can very very quietly take game it's going to be
more efficient like I mentioned with these projectiles than a 22 and I can
see how if you did have a 223 survival rifle is something that you intend to be
able to kind of live off the land or whatever with I think it'd be smart to
have a magazine loaded up with these things just because of that quietness
factor but let's take a look at the ballistics here and we're gonna see just
how inefficient this cartridge is let's start this conversation by talking about
energy this is my supersonic 223 load at 25 yards it's moving out faster than
2500 feet per second and it's producing over a thousand foot-pounds of energy
and that's going to be almost four times as much as I get out of a 115 grain
9-millimeter bullet from my pocket pistol so you can see why even a small
rifle round like this one can be very effective even at longer ranges now by
contrast this is the subsonic 22 that's a 40 grain bullet let's see how much
energy this thing produces 98 at the muzzle so that's less than a tenth of
the energy of that faster 223 that is very very low this is
all less than a hundred foot-pounds of energy and all these ranges look at this
so let's take a look at the subsonic 223 and see if we can kind of split the
difference a little bit okay yes even at 25 yards here we're still over double
the energy that we got from the the 22 so that's a good reason to do a subsonic
223 versus maybe a 22 this thing is going to deliver a lot more energy just
because you have that bigger heavier bullet and then look at this even at 600
yards I'm still producing 112 foot-pounds of energy which is more than
that 22 ever developed even at the muzzle to throw that subsonic 223 into
stark relief let's take a look at the supersonic chart here and we only start
getting into those speeds and energy levels
once we get past 900 yards on the 223 chart energy is only part of this
equation also take drop into account over here with the 223 subsonic at 200
yards we're dealing with a drop of about 5.8 milliradians
and we're dealing with windage at 5 miles an hour
of about point 4 milliradians by contrast the 22 at 200 yards has a drop
of about 8 point 7 Miller ad uns and 1.3 that's almost three times as much
windage at 200 yards so what is a subsonic 223 is it just a gimmick a toy
just something you play around with it the range yeah it is and it is kind of
fun it's really just kind of a hoot to hear the almost nothing that comes out
of the barrel it is so darn quiet but it also is I think a really neat training
tool for being able to read wind if you want to be able to try different
distances and really be able to test if you're reading your wind right this is
going to be a very finicky thing to deal with and pretty tricky to get on target
it's also going to be I think effective for game like I mentioned
earlier small game so if you do have that survival rifle and you want to be
able to very quietly and cleanly take game I think this is a really neat
cartridge that splits the difference between a supersonic 223 that's going to
make a lot of noise and a subsonic 22 that just isn't going to deliver all
that much energy thanks for watching if you like this video be sure to LIKE
