Wouldnt the extra space around a .30 cal silencer kinda defeat the purpose of trying to suppress the noise created by a smaller caliber like the .223? I thought the physics regarding a silencer were to try and capture the sound within the baffles of the silencer. If you used a larger caliber silencer wouldnt this allow more gasses to escape the barrel and allow more sound to be created?
I'll ask the question another way.
Which would work better? A .223 caliber specific silencer or a .30cal silencer mounted up to a .223?
Personally, I wish I would have bought the .30 caliber can now. Instead of the dedicated .223 can. I like the multi-purpose aspects nowdays.

The can is most efficient while shooting a bullet matched to the can, and less efficient shooting a bullet smaller than the can. But as you will see while doing your research, a 30 cal can is longer than a 22 cal can. That added space will be beneficial when shooting 22 cal bullets from a 30 cal can.
Also, if you look at some of the can manufacturers, they list a noise reduction of XX decibels. A way that was explained to me that really helped me understand all this is find a pair of hearing protection with a Db reduction rating the same as the can you are thinking of getting. Shoot your unsuppressed rifle using that hearing protection. What you hear is roughly the same as what you will hear using the can and no ear protection.
This is where the efficiency thing comes in. The Db rating of your can will not be as good using a bullet smaller than the can was designed for. Exactly how much I don't know.
Another HUGE thing to remember is suppressors are manufactured so that threads per inch match caliber.
So a 22 cal can is threaded 1/2x28, stand threads on all AR type rifles with flash hiders or the like.
6.8 cans are threaded differently....
30 cal cans are 5/8x20 I do believe. (not 100% sure, but you get the point)
So, is you have a collection of AR's and a bolt action deer rifle in 30 cal and want to use one can on all rifles, you can, but you will have to have all of your AR's rethreaded to 5/8x20.
So in your endeavors to be more frugal and save money on cans, you will spend some money rethreading some rifles and making them only usedful to you. Someone else may not want that rifle with those odd threads on it.
Just food for thought.

I agree, except if you go with a fast attach can. The QD flash-hiders come in different thread pitches. The YHM 30 cal can will screw right on the YHM .223 flash hiders. Same with the AAC now. 30 cal.762-SD 51-tooth, will screw on the 51 tooth M4-2000 mounts.
