I fully grasp subsonic.... I've shot long & short with cans before, all subsonic except some .22LR standard V just to hear the difference.......
My point was large calibers, as Robob's can will handle up to 300WinMag... I'd like to hear a bigger bore ballistic round through a can....just to satisfy my curiosity...
I’ve got a suppressed .300WM (actually a .338 suppressor), and it’s definitely quieter than an unsuppressed .308 going off. The at-muzzle dB is probably only 15-20 quieter than an unsuppressed .308 (which is still A LOT quieter), but back at the shooter’s position, it’s probably more like 25-30.My uneducated guess is that 300 Win Mag sounds like.... .308.
Probably helps a great deal with flash-suppression, though. That may be its role in the reach-out-and-touch-someone caliber/loadings.
It’s hard to describe how it sounds, comparing it to another gun, just because the suppressed sound signature is so different. Regardless the peak dB, you still get that WUMP-HISS sound of the can, and you notice more of the down-range crack/tearing sound. It’s not OHSA hearing-safe, but I will shoot it in the open without ear-pro without any discomfort.
Shooting a .338 LM through the same suppressor is only a little louder, maybe 3-4 dB, but the sonic crack is VERY noticeably louder.
