223 Subsonic Ammo

econ 45. you hear a lot these days about subsonic ammo and suppressors and all that kind of thing and maybe you don't know anything about it i know nothing about it of course that's never prevented us from getting a camera out and talking right actually we know a little bit about it and uh not experts maybe but we know a little bit about it and i thought just try to clarify some things maybe for you while we have some things here today uh that might help us do that need props good props for this sort of thing it's making a real props okay two two three uh that's one of the topics here because uh two two three five five six is a very fast little round isn't it and as we all know if you've been around anybody firing it or you have fired it you really want ear protection the best you can come up with is very loud let me just show you that if you don't believe it okay pick out the old daniel defense and take a couple of shots here oh i dropped the magazine oh someone closed the bolt i bet that was john it was john he was admiring this firearm i had it open so it'd be easy to seat the mac uh i'll just take a couple of shots at that uh oh propane tank notice now it will go through it i'll shoot near the top there see it hitting the straw behind there okay that will be important later okay just want you to notice that click we're clear all right that's your full power ammo and in order to get the sound of that down uh considerably you've got to do something you got to either reduce the velocity dramatically uh and or put a suppressor on it all right and let's just do that you want to this is a mossberg mvp we're going to shoot the same ammo and we have a uh let's see i've now forgotten what we have yeah we have a silencerco suppressor on that the shaker and let's just take a couple of shots with the same ammo i won't even put my ears on and that's not silent but it's not uh too bad either okay i noticed the long mags this thing will take ar mags but it doesn't do as well with the longer ones i've noticed i didn't bring a 10 round mag out so there we go get one in the chamber there we go safety on well let's leave my ears off all right i'll shoot the propane tank there in the same place pretty much near the top okay notice it's going through getting in the straw behind it even though it's not as loud you still got basically the same velocity okay even with the suppressor okay full power ammo there all right so if you want to reduce the sound you've got to do something and you notice you don't notice it as well of course at home but i didn't need ears it didn't hurt my ears if i was going to shoot a lot i might wear ears on it it's one of those things uh you're talking 3000 feet per second you know with with five five six and that that's five five six ammo it's not two two three probably 31 32 uh 100 feet per second but you can bring it down to where it's civilized right with the suppressor it you know it does a lot of things it reduces the airflow back in it baffles it and it just creates a quieter experience for you done that's what a suppressor does it all has to do with that just getting that on the end of the barrel whether it's a bolt gun or a semi-automatic or anything okay uh so you're suppressing it to some extent there with some ammo you can totally almost totally suppress it very difficult with two two three how are you gonna suppress three thousand feet per second or even two thousand feet per second right what is it that makes the sound it makes most of that loud noise it's that crack you get from you know breaking the sound barrier and of course the speed of sound is what boys and girls it's over 1100 feet per second 11 27 so you've got to get under that threshold in order to make much difference whether you have a suppressor or not it's the reason you're on the range and you hear somebody down the way shooting something that ah your head just about you know explodes you know it's so loud the concussion and everything it's that velocity it may be a big bore gun as well but it's at velocity okay it's what does it because again as we have demonstrated in another video i don't remember the name of the video 22 caliber is 22 caliber we shot a pan or something with a 22 long rifle and we shot a pan right beside with one of these the holes are the same you know calibers caliber the difference mainly is the velocity between a 22 long rifle and this these are a little heavier but not a lot heavier what 40 grains versus 55 it's the velocity and the velocity equals noise okay so that's one of the things now one question we get a lot whenever we bring out a suppressor and you know nc silencer comes around occasionally we get some cool stuff uh they help us with and uh and a comment you see now again it's from new new shooters maybe maybe it could be from anybody but uh is why why are you shooting uh why aren't you shooting subsonic ammo you know if you have a 223 556 get some subsonic ammo you know if you want to be quiet you want to be silenced you want to be really suppressed why are you shooting regular ammo yeah well you can do that and that's what we have today we have some of this it is it is a subsonic it's under 1100 feet per second i'm not sure exactly what it is and it is 556 or 223 and it does become more quiet let's take a couple of shots with it and i'll show you if you don't believe me i've got it in one of these big mags again but okay get it i mean that's funny you know we have messed with this rifle son and had not uh experienced that with the 10 round mags or 20 round mags there we go all right now i definitely should not need my ears let's take a couple shots here i can shoot this steel with this i'll shoot the cowboy i'll see let's not shoot steel let's shoot the let's shoot that that stump see now that's pretty quiet for a 2 2 3. the only way you're going to get that is with really low velocity not breaking the sound barrier and then a suppressor of course on top of that that's how you get there all right now what are the disadvantage well the advantage is it's quiet but what have you done there you have created a firearm that is very much like a 22 long rifle have you not let me think about it you know here's points some 20 long rifles cci the velocity is 1235. that's the kind of stuff a lot of us shoot and you know it actually has more velocity than what i just fired because that's under 1100 and i don't know what it is maybe a thousand feet per second or something or 900 and so so when you do have subsonic 556 or 223 one of the points here is you have essentially turned your fairly powerful rifle into what a 22 long rifle maybe 22 magnum i don't know you may have a more scientific uh information i think it's probably between 22 long rifle and 22 magnum you know power and velocity that kind of thing so so you but you've really reduced it okay so there's not a lot of advantages to uh to to uh to shooting subsonic two two three depends on the purpose there's always a specific uh purpose or an operation where it might be exactly what the doctor ordered but just bear in mind you're turning it into a 22 magnum or 22 long rifle maybe okay let me show you something here we happen to have a 22 long rifle let's uh let's take a shot at that propane tank and this is ready to shoot because we shot a couple shots here i'm going to shoot right in the side i'll put a couple there kind of to the left of it there we go we're on safe i got three hits in a row there kind of stacked on top of each other now now we can shoot these out of anything they don't have to be silenced let's shoot about this thing how's that okay i want to show you something else about it all right uh i'll shoot these to the right now this is a two two three this is five five six remember those first ones i shot they went through that thing like it was butter and see what these subsonic rounds do i'm gonna shoot just to the right of that line of three huh is that a malfunction oh i bet i know what it is it's not powerful enough to work the action see let's put another one there you end up with a semi-automatic or a single shot a single shot okay it will it doesn't even move the bolt okay if that tells you anything put that back up there let's go down and take a look at it where's my official pointer here it is official plane okay now these are the 22 log rifle okay and then that's the subsonic 223 in fact they didn't seem to hit as hard okay so on the right you've got the 556 left you've got 22 long rifle all right now again and then yeah up here you got the full power and they just they drilled a hole in the front and they drilled a hole in the back and went out into the dirt okay so now again uh we're not scientists i'm not a scientist even though i have played one on tv but that's just a kind of give you a ballpark uh idea about what the difference is and what you are doing with a five five six or two two three when you bring it down to subsonic level you lose your punch whatever punch you have some folks think the 556 has no punch to begin with right but so you're turning it into something in the ballpark you know whatever it is a little bit a little bit stronger generally i think most people would say than uh a uh 22 long rifle and steel sometimes is not the best you know indicator of that but it gives you some idea you know because most things with any velocity punch right into those things and go out the backside so that's what you've got you reduce that's the reason i think that 556 subsonic is not more popular you know you don't see it in the stores stacked oh yeah everybody's looking for that let's get a suppressor and shoot a bunch of five five six well for one thing you saw what it did it did it does to uh an ar it turns it into a single shot you know it doesn't work the bolt for one thing and that's that's one of the negatives and it also uh it's heavier it's generally going to be a heavier bullet and so the rifling uh is not going to have probably a twist rate that's going to stabilize it as well either so for close range it's probably going to be fine just depends on what you need it for all right so anyway we wanted to make the point about the 556 especially because we get a lot of questions about that and then just again just demonstrate you know suppressor what it does the the velocities you know how much you have to reduce them or to really suppress very much and then also you notice when i was shooting uh the full power ammo with the suppressor it does make it a lot more civilized that's one of the attractions of it and that's why a lot of people do put suppressors on on ars they can go out without their ears really if they want to you can wear your ears if you like it's kind of a not like depending on your suppressor it's like shooting a 22 long rifle something in that vicinity maybe a little less and uh obviously that's that's a long way from a standard 556 right right if you've ever heard that before so uh that's one reason the 300 blackout uh it became it came into existence i started to say it became so popular i don't know how popular it is really yet but it's a heavier bigger bullet going subsonic so generally speaking i think i'm pretty correct in this if you're going to be shooting subsonic it might be better to have a heavier bullet because obviously if you got a bullet going 800 feet per second or a thousand feet per second and that's it then maybe heavier is better right so big old 220 grain bullet going a thousand feet per second it's going to hit harder than you know a 50 grain bullet or a 75 grain bullet going the same speed we all know that just like you know i'd rather get hit with a little piece of gravel going 800 feet per second than a hammer you know going that or oh i'd rather get by the yeah the gravel in the hammer or a pea than the than a hammer you know stuff anyway i lost track of my point didn't i uh so anyway this little information hopefully uh didn't confuse you too much but uh demonstration of what a suppressor does and how it kind of works and the advantages disadvantages of two two three so that that's what kind of brought this up john i have talked about that we had a lot of points questions about it where is your 223 subsonic ammo i have no desire to go buy a bunch of 223 subsonic ammo even if i had a full-time suppressor that i could pop on my 223 anytime i wanted i don't know that i'd even have any subsonic 223 in the house maybe other than just for a video okay so that that probably sums it up as well as anything so anyway life is good

And that's why we have gas regulators. Not on the AR-15 family of rifles, though, unless we're talking the newer HK416s, the Ruger SR-556, and a few others.

[u/Fidy1]

but thats not even semi-automatic

[u/Le4ky-F4ucet]

Having the suppressor on the gun might give it enough blow back to cycle the bolt though

[u/WRFinger]

That's why I prefer gas piston variants of the M4/AR platform, like the HK416. Direct Impingement gas systems are dirty and antiquated IMO

[u/praisedtimon]

a subsonic 223 is just a glorified .22 LR.. ( AKA useless in combat)

[u/Kitsu_Gaming]

You mean it turns the M4 into a single-action rifle. That's a lot different than semi-automatic.

[u/shalashaska994]

The bigger issue is that subsonic .223 is practically equal in every way to a .22lr

[u/zironicdk]

This can be fixed with a little upgrade to the gun (or change) You can easily get a AR15 to cycle with Sub ammo.

New bolt and buffer/sping.

tho, the main reason for silencers isnt really to make them quiet - its to make them less loud, in LE/MIL you just wanna not blow gas in your mates face, and or have less flash and ring/echo indoors.
