SD Ammo

[Babyjebus117 0]

So the point of this game is to make a more realistic type of zombie survival game right? Why not make SD ammo regular ammo, for instance, the M9 SD weapon can only use SD ammo right now, but In my opinion should be changed to any type of M9 ammo. I thought it was weird that silenced guns had their own type of ammo seeing as how in real life there is no such thing. Just pointing it out there because after I usually find a silenced weapon with ammo all around it, it becomes obsolete once I use up all the ammo seeing as I cant find anymore. Turns finding a rare gun useless :(

Very true although sub sonic ammo is real you dont need it for a already suppressed weapon

Subsonic ammunition. Look it up.

However, several weapons do not make use of subsonic ammo and so it's not unreasonable to suggest they use the same ammo as the regular version. If I understand correctly, a suppressed M9 uses regular ammunition. The MP5SD also uses this.

You have no idea what you're talking about. Subsonic ammo eliminates the ballistic crack of the bullet to reduce noise. It does not eliminate or reduce the sound of the bullet being fired which a suppressor does (along with muzzle flash).

If you don't use a suppressor with subsonic ammo, congratulations you've just decreased your accuracy and range for almost no benefit whatsoever.

But can you use non subsonic ammo with a suppressor?

there is massive amounts of sd ammo in the nwaf armory and at most heli crash sites you will find an ammo box with loads its useually to much to carry , this is how i keep mine filled and most of our tents . you just gotta look so at least that really rare gun of yours stays with you . the ammo is definatly worth the risk

Lol, yes you do.

Firstly, you must use a subsonic cartridge if your pistol or rifle is equipped with a suppressor to reach complete silence. A subsonic ammunition is silent because it does not goes past mach 1, and don't cause the caracteristic "clac" when the sound caused by the aerial shockwave reach the ears of someone on the trajectory of the bullet.

Secondly, shooting a non subsonic ammunition through a suppressor causes over-pressure and can damage the suppressor itself with debris and blast.

The main differences between these rounds are primarily the powder type and charge, and in some rare cases the rifling of the barrel (for some fully silenced weapons not intended to shoot something else than subsonic cartridges, like Mp5sd variants.

Wich explains why a subsonic round will travel less far than a classic one.

In ARMA2 this phenomenon can be observed with long distance shooting using suppressed rounds and guns, the in-game ballistic showing clearly this with scoped rifles.

For an almost subsonic round like 9x19mm para/luger (355meters/second or mach 1.04 with a 9x19 luger) the difference is not THAT big, but still: does the unsuppressed M9 uses a civilian 9x19mm? Or the overpressured military round 9mm+P ? My bet on this one.

Therefore, using this round with a suppressor would be almost as dangerous for the shooter than it is for his target, as the suppressor would be slowly rendered ineffective and could dramatically break.

Suppressed versions of handguns used by specops, commandos, whatever special unit wich has to use them, usualy shoot lightweight loads rounds.

So yeah, you can still shoot these round into an UNsuppressed weapon, but it is not dangerous, unlike shooting 9mm NATO in a M9...

Except if you would like to have an M9's slide cutlass pierced into your eyebrow... And possibly your brain.

So tl;dr:

You don't shoot normal rounds used with unsuppressed weapons, with a silenced/suppressed weapon.

For both effective suppression of gunshot sound and bullet travelling sound. And for security reasons.

Period.

Depends on the suppressor and weapon design. The MP5 for example shoots supersonic ammo but the suppressor uses gas bleedoff to slow the velocity to subsonic without using specialist ammunition. Some designs will use supersonic rounds and won't slow their velocity down but will quiet the firing sound and hide muzzle flash.

In some cases though, the design means you must use specialist ammo, or risk very bad things happening.

Ok my bad thanks for explaining

That's interresting! Never heard about that, do you have any link on the subject?
