Baffle and endcap diameter have NOTHING to do with internal volume, period. A suppressor that is constructed exactly the same with the exception of diameter of the opening will always be quieter if its caliber specific, period.
What you guys are talking about is the amount of overbore and all manufacturers are different. Surefire and OSS have LOTS of overbore and on some models a .243 could very easily be shot through a "22cal" can.
Best advice is refer to your specific manufacturers and leave the internet experts out of this before something bad happens to you or your equipment.....
Oh really, Most 223 cans are 5-7 inches long with a diameter of 1.25-1.50 inches. Most 30 caliber cans are 10-11.5 inches long with a diameter of 1.50-1.75 inches. That's a [beeep] of a lot more air volume.
Silencer's are the same as muffler's on car's. The larger they are, the more air/gases they trap though the baffle systems.
It's no different than the sound difference that you get from a Cherry Bomb glass pack or a production car muffler on a car. The production muffler has more volume to trap the air/gases coming from an engine, so it's a lot quieter.
I've only been shooting suppressed for a couple decades, and have 7 suppressor's in rimfire, pistol, and rifle caliber's. While most of the manufacture's do or pay for testing with expensive testing equipment, I can tell you from experience the sound differences between different size suppressor's.
