Just about any firearm can be effectively suppressed, even those that use supersonic ammo. Since the silencer is only intended to suppress muzzle blast, action and bullet noise should never be taken into account when determining silencer effectiveness. Of course a person needs to take all sources of gun noise into account when deciding to whether or not to wear hearing protection. The 338 RUM in my video linked below definitely requires ear plugs when shot under weather protection.

The only unsuppressed firearm I have ever heard that was hearing safe without ear plugs was a 22 caliber file using CB's. When I used CB's in a pistol, it hurt my ears. Anyone who claims that an unsuppressed firearm is 110-130 decibels is acting irresponsibly. Even a 22lr pistol is about 160 decibels when measured with the proper meter and microphone. Sure I can use a cheap noise meter I bought at the mall and call my 30-06 safe to shoot without ear plugs, but that is being dishonest. A meter/microphone with a response time of no more than 20 microseconds is needed.
