As my first post here, and only a meager 250+ hours with this great game... but I do have a bit of experience with real world weapons... and various weapon cartridges (or rounds, or bullets, or whatever you want to call them).
No suppressor needs special ammo. They typically are used in conjunction with sub Sonic ammo because suppressing super Sonic ammo will still result in a Sonic boom.
True... to a point... it's not a sonic "boom" per se, a sonic "boom" is produced from a high velocity (speed in excess of the speed of sound) high mass object, such as military jets, the former space shuttle and the like... but more of a sonic "crack" as FileMachete describes. It's extremely difficult to produce a sonic "boom" with any caliber of firearm. But I'm likely being pedantic. Forgive me if I am :distracted: .
FWIW: Same round from same lot/maker will vary in velocity a bit. Cheap stuff maybe ~30 fps. Adding a can may up velocity, but a different can may not. Really doesn't matter as the change is so small.
This is not actually accurate. Cheap ammunition can vary far more than 30fps, more around the range of 300 fps... in most cases even more. Well known, accurate, mass produced ammunition can vary approximately 200-300 fps per round easily. Carefully hand-loaded cartridges can vary more than 30 fps with ease.
Containing the expanding gases of the propelling charge, if effective, does greatly reduce the muzzle blast & flash. Making it quite a bit harder to pinpoint the source by visual or auditory senses.
Very common to use a suppressor on supersonic rifles since the above still holds true. Yes there is a loud supersonic 'crack' due to the bullet but to someone say a hundred yards away that 'crack' isn't a pinpoint source, the best they can do is more a 45 degree arc of, "somewhere that way".
And worth noting that even with a supersonic round the bullet breaking the sound barrier is still considered below the damage threshold for normal hearing. Meaning it's generally considered 'safe' to fire even a full power 7.62x51 or larger with a good can without hearing protection..
Not exactly true. Most mast produced suppressors will only... suppress... the sound to a level that is "safe", that is, less than 140db, which is still very loud and can easily damage anyones ears with repeated reports. Especially from semi-automatic weapons fired at semi-high rates, let alone automatic weapons. Most suppressors will still require ear protection for anyone firing the real world weapon at any weapon range.
Fun fact: in a number of countries it's considered rude to not use a suppressor while hunting. Those same countries often don't regulate suppressor purchase or ownership; they focus on the firearms themselves. Also, more and more US states are adopting laws to allow suppressor use while hunting.
Their main drawbacks, other than price (and tax stamp/legalities/etc in US), are muzzle weight and added length. Most felt on handguns, though adding a couple pounds onto the end of long rifle barrel is quite noticible.
Somewhat true... many countries limit the calibre of hunting rifles... if allowed at all. Granted, in the USA suppressors are largely legal, but in many cases they do require a FFL and paying the additional tax per suppressor manufactured (not to mention the fees required in obaining an FFL). And when one weighs the benefits and negatives with suppressors... personally, there's not much real world need for one. They don't sound like the typical movie "pffft", any suppressor is much louder than any movie sound track. Depending on the machining of any given suppressor, the accuracy and sound suppression gained, is in reality, minimal.
But... 7d2d is a game... its not reality... nor should it expected it be, imho... So none my meager opinion should matter whatsoever...
Just my two cents...
