Subsonic Suppressed 223 / 5.56




What do you think about this video?

gunz and music: I plan on getting a .223 and making a subsonic load, i dont want a heavy bullet though. Will a 1:9 with 55grain subs be stabile 

lmorrison17: Id like to find some subsonic load data for 75-80g bullets to try in a 1x8 twist 

ms3bani: nobody.

paul axton: All he needs is a 1:7 twist barrel and coupled with a suppressor it will cycle perfectly.

Kevo F: 100gr bullet (hard to find) with trail boss, and a 14.5" 1/7 twist suppressed barrel will cycle. Also extreme shock sells some 100gr subsonic loads that will cycle but they're like $45 a box. Theres a video of it somewhere. I don't know maybe you found a load by now.

Tom Balotte: Youtube won't let me type a long and detailed explanation so im gonna have to shorten it lol. .223/5.56 are designed to go fast, real fast! One way you can get them subsonic is by reducing the powder, but if you do that the action wont cycle. The other way is to load a very heavy bullet so you get enough psi for a cycle but still remain subsonic. You can safely shoot a 55,000 psi cartridge in a .223 chamber. There is plenty of load data for a 100gr bullet you just have to find it.

Claude Rains: @panteraboy1988 The problem is not in the bullet, its in the gas system. You have two choices either make the gas bleed hole bigger or get a softer spring. I would go the bleed hole bigger at least it will still function without the AWC. The recoil with the light spring would not last to long. You might also know shoving 100 grain bullets in that thing, you get over 50K PSI barrel pressure and you could blow the bolt up in you're face. If you are left handed is not a good idea.

russr: @panteraboy1988 looked up extreme Shock 100gr, looks like total crap for reviews, and dont see a 100gr lee mold.

russr: @8digitPDX i havent done varmint bullet tests at that speed yet to see of they still expand, but FMJ even at subsonic speeds will still penetrate a LVL 3 vest.

vampov: @russr Cant you adjust the gas flow or something to make it so it can cycle?

russr: @heyheyheyhey260 subsonic ammo doesn't have the power to cycle the action of the gun.

Mavis Blinnie: Have you come up with a round that will cycle yet? Theoretically speaking, if you used a heavier bullet, you could get more recoil out of it. Or maybe a lighter buffer?

heyheyheyhey260: why do you have to manually eject every round after you fire? arent there rounds that cycle the weapon automatically? im not very good with bullets, im a beginner....

rbowen47: I use that same load, and it is sweet

Jack Attack: @russr I know it is possible. Extreme Shock (shudder) makes a 100gr load that cycles the action and remains subsonic. So it is possible to load a heavy bullet. They say you need a 1:6.5 twist to stabilize it, so if I want to load a 77gr then a 1:7 ought to do it (I hope)

russr: @0men sub sonic ammo dont have the power to cycle the action

0men: Why is it a single-shot?

crazydriver1978: congratulations: you just converted one of the worlds most efficient vermin hunter into one of the worlds most under powered quiet difficult bolt action sniper rifles

russr: @mlacey56 sounds like a pellet gun

frankdreban: Nice. I got quite a bit of Trailboss a while back to do some subsonic .308 loads. What's your case density with the 4grs? Did you ream out the primer pocket and use magnum primers or did you keep it at small rifle? I wonder if you can get a lighter buffer/spring to help it cycle. Have you thought of using 77gr tips to give it some extra oomph? Would also help to avoid S.E.E., I'd imagine, since you'd have to increase the amount of powder to push the bigger pill the same speed.

russr: @miamiwadecounty3 not in 223 in a AR, "some say" that have seen 77gr subs cycle, but till i see a vid, i dought it...

russr: @jbolinger4354 small rifle

russr: @littlesurfer519 this powder is made for light charges... that "can" happen with other powders... this is a pistol powder. havent shot them with out the can..

miamiwadecounty3: Is there any weapon configuration that will cycle sub-sonic ammo without having to manually eject each round?

callmepyro: @imjustwonderful Actually it would make the gun cycle worse (assuming it would cycle at all with his subsonic ammo) a suppressor will increase the back pressure significantly. a suppressor holds the expanding gasses in, making the muzzle blast a bit quieter. he is using very "weak" ammo. Its loaded with less gunpowder so the bullet will travel under the speed of sound thus SUB SONIC. hope that helps

littlesurfer519: wow, 4 gr! Thats crazy. Pretty much destroys the myth that super light charges can ignite all at once, causing it to explode. How do these sound without the can?

Jack Attack: any load data for some heavier 223 subsonic loads? 68 or 77gr?

HellaFlushEvo: I though =t Captain Picard uses phasers :)

russr: @heyheyheyhey260 nope...

GR3B3N: @miamiwadecounty3 shorter gas tube\ lighter buffer or silencer with obturator.

russr: @labartic the problem with the heavier bullets, is at that slow speed, i dont think even a 1-7 twist will stabilize it..

russr: @Cigmachines correct...

Cole Boxwell: you need some lube lol, but nice video!

rbowen47: @russr Don't you get tired of retarded questions?

imjustwonderful: would the round cycle if you didnt have the suppressor attached?

russr: @panteraboy1988 who makes 100gr 223 bullets?

Tom Balotte: These guys called Super Shock. I was talking about pouring your own tho. Lee makes 100gr molds for 223. Fouling of the barrel is minimal at small velocities and if you put a gas check on your cast bullets you can almost eliminate it.

8digitPDX: Now I see the utility of those new style uppers with the large sidelever FAL style roostering handles. It allows you to swap between subsonic and full power hard ammo and be more efficient hand cycling the action with the subsonic stuff. What do you think the downrange stopping power is comparing the subsonic .223 to 9mm out of a similar carbine? You get a different class of power and accuracy when using 9mm ammo that is tuned to a 16" barrel.

Tom Balotte: Get yourself some 100grain bullets and find some load data that'll match your powder for a subsonic round. It'll cycle every time with that heavy of a bullet.

Goldngun: @labartic I've had tremendous success with nextreme shock subsonic asp!

russr: @labartic tweek the trail boss load, its still the best powder for that use...

curseofa5r5a: proff that the AR-15 jam after every shot... just joking

RIPGeorgeCarl1n: Damn dude. Lube the charging handle?

mlindsay527: I love subsonics, but in .22, a bolt action or lever action .22lr is the ticket.

Cigmachines: So the subsonic rounds just dont produce enough gas to allow the receiver to complete its cycles??

Mchurchwell: WWIIOL and OT is teh best!

Jack Attack: Thanks for posting, you can truly find anything on youtube :)

Darko Ristic: 5.56 is too light to be effective at subsonic velocity. I'm not saying that it won't kill you at blank point range, but at greater range, it's a joke.

jah2mail: @russr dought it too...

russr: @frankdreban no need for mag primers, dont see any way to make these cycle...
