My suppressed Whisper (using H110 powder) was very close to that. With these new 231 loads I have been trying, I fully expect the noise to actually register below the sound signature of my spring piston pellet gun. Like I said, I'll post these and the sound results of the 308 sub loads as soon as I can get this tested.

JF,
That sounds fascinating and I'll eagerly be awaiting any results you have! When you were testing before, were you using the Larson Davis 800B sound meter with a 1/4" mic, with the muzzle 1 meter to the right of the mic? I ask because 113-115dB actually sounds a little low for an adult air rifle.
BTW, would you tell me more about this HTG suppressor? I've been looking for an upgrade.
