Am I the onyl one who LOVES this weapon

Except the SD rounds aren't subsonic in DayZ so I guess you're the one that doesn't know shit.

Did you skip the OP's post? He said that it was stupid to have separate ammunition for a suppressed weapon with the implication that the ballistics of the ammunition are irrelevant to suppression. A suppressor does NOTHING in regards of preventing the supersonic "crack" of a round, which is the main contributor to noise when firing. The OP is correct to an extent, but only when you apply it to the M9 SD in game. 9mm is naturally subsonic, and therefor standard ammunition can be used with a suppressor to achieve the maximum effect. 5.56 NATO is supersonic, so firing a standard 5.56 through a suppressed weapon will do pretty much nothing to reduce noise. To compensate for this, rounds have been specifically designed with a lower powder charge to propel an otherwise supersonic round at subsonic speeds, removing the supersonic "crack", while the suppressor does it's job of allowing excess expanding gas to disperse more rapidly than from an unported barrel. Most gas operated rifles have issues using subsonic ammunition, because it often lacks the extra pressure to cycle the bolt. This is why you rarely see a stock suppressed AK variant, because you have to manually chamber every round after firing due to the pressure lost from using subsonic ammunition. I say again, the OP doesn't know shit about firearms, or at least how weapon suppression works.

I also can't seem to find a list of Arma 2 in game muzzle velocities. Would you mind showing me where you found them so I can verify you claims about me not knowing shit?

I love this gun ...

I understand all the mechanics (didn't know about the manually chambering every rounds tho). The point I was making is that, there is no subsonic ammo in DayZ so the SD ammo makes no sense in DayZ. And I found it out simply by shooting over someone with silenced weapons. It still makes the snap. To my understanding if it still makes the snap then it shouldn't be any different than regular ammo? Or maybe I'm mistaken. You can probably clear that out.

Yep redneck grammer from SoCal. Oh wait, you probably don't know where that is, or who lives there.

I'm from West Virginia so he's got the redneck thing bout right lol

That's not 100% true unless its different for rifles. I own a .357 that is loud as fuck but when i put the supressor on im able to shoot in my back yard without my neighbor even knowing im doing it. Oh and btw, The whole ''op doesnt know shit about fire arms'' this was just a friendly post to see what people thought, not a chance for a fucking tool like you to put in his two cents.

First line, subsonic rounds. They are in the game, I would guess the reason you can still hear a crack above your head when someone is shooting at you is just that, so you know someone is shooting at you. Just a guess though, I don't know why you would still hear the round otherwise, or why you should anyway.

I think it's just an effect in DayZ. Obviously, a supersonic round traveling down range will reach it's target before the sound does, but "close calls" definitely have an audible "whizz" to them. I don't think the "crack" in the game represents the round breaking the sound barrier, but it hitting a solid object. The SD ammo in game seems to be an attempt at adding subsonic rounds, because shooting SD ammo through a non suppressed weapon has negative effects on the shooter (or is it regular Stanag mags through a suppressed M4?). Either way, using them in the incorrect combination makes your accuracy loose butthole. Not realistic, but it is trying to compensate for the fact that using a suppressor and supersonic ammunition is a bad thing.

It all depends on your muzzle velocity. I have a .357 mag pocket revolver and a suppressor won't do shit for it, namely because revolvers with unsealed cylinders are unable to be suppressed due to gas leaking out the base of the barrel. I know that 180 grain .38 ammunition is naturally subsonic, like 9mm and .45 ACP, but if you are legitimately shooting a supersonic .357 round out of a suppressed rifle and it isn't producing a supersonic crack, you should be awarded the Nobel Prize is physics. There are a lot of factors involved in the process though. Barrel length, chamber pressure, rifling twist ratio, quality of the ammunition, etc. I've never fired a .357 from a rifle, but I imagine that the normally supersonic magnum round is slowed down to subsonic speeds by the additional friction from a longer barrel. Just speculating though without putting your rifle on a chronograph.

Edit: Are we talking about .357 magnum or .357 SIG? I'm almost positive that .357 SIG rounds are naturally subsonic.

There was this one time my friends were on electro hospital (we are all on teamspeak, I'm pretending to be AFK) I log in with a different name, go to electro hill and start shooting above their heads. No way the bullets were hitting the hospital or any buildings for that matter. They were all "I can hear snaps, someone is shooting at us, take cover!".

I also tested this with silenced m9 shooting above someone's head (like in the sky) from like ... I dunno 10-20 meters. He still heard snaps. I could understand whizzes but those were snaps, exactly the same like from regular ammo. The description says they are subsonic and they have different behavior but they still make snaps... It doesn't make sense.

it's a Dan Wesson 357 Mag with 4" barrel on it. I had a custom supressor made for it. I had a gun smith put everything on so im not 100% sure what all he did.. if you'd like I can get you a picture of it pretty cool looking.

Only thing I see in the video is fat american playing with huge guns to compensate penis size.

Things always go like this with redneck's america.

Those who beat their guns into plows will plow for those who do not.
