Interesting, I will have to check my Noveske 6.5G bolt later.. what am I looking for? What's the difference between "special" and "standard" JP bolts, or did you just mean the marking?
The Pew data shows that the Ultra 9, Nomad-L, Hyperion, Enticer series, and the full size Otter Hydrogen and PR30L all have great FRP control in 308. In my mind that makes all of them fantastic bolt gun hunting silencer candidates. The Ultra 9, Enticer, and Hydrogen in particular because they...
Ray confirms having reproduced the raw data. I believe it was Zak who said the waveforms lined up, a year or two back. I can largely achieve "good enough" results while using slightly different ovens and ingredients as the pictures in cooking recipes too. The type of validation you are narrowly...
Accuracy is definitely paramount, and only precise cans are interesting. I agree with all of this except the premise that because accuracy matters sound does not. Especially since my hearing is relatively intact and I want to keep it that way. That means knowing going in the risk I'm exposing...
1/2. I understand any consumer's categorical misgivings about a proprietary rating. That's why I asked specifically about the raw data. Help me to understand: when I ask whether Jay's peak dBs and waveforms published are inaccurate, are you saying that such waveforms and peaks are flat...
Before Pew Science, peak dB was the only standard. There was zero discussion of risk assessment, certainly not to consumers armed with OSHA alone. In the Pew Science review of the Ultra 9 that was publicized nearly two years ago now, there are no fewer than 15 peak dB numbers listed, open for...
140db is useless but raw dB collected in a barn is science. Dosimeters are great and what we need instead, but vaporware AHAHA means more than the obvious industry standard that exists and is anecdotally validated every day. Industry sure is quiet about disputing its results. The silence is...
What I actually said: "None of these are good for a full day at the range. All of these are good for a mag a day." If we just keep moving the goal posts of "hearing safe" around to exclude hunting, limited practice, etc we can keep our collective understanding stuck in 2019 forever. I think I...
Staying on topic: here's a short list of subsonic host/can combinations that are louder to the shooter than the Hydrogen-L, with the Ultra 9 on 20" 308 thrown in for good measure. What the rating number means: https://pewscience.com/silencer-sound-standard-suppression-rating None of these...
I'm not familiar with all that, but I have seen Bryant deferring to Jay on this stuff and Jay says a 22" 6.5CM Hyperion is quieter to the shooter than an 8" 300BLK subsonic with a Q Trash Panda. Blanket statements that all centerfire supersonic cartridges aren't hearing safe is belied by data...
You'd have to define "hearing safe." Another way to say it is that every cartridge you shoot out of a gun, regardless of what's hanging off the muzzle, represents some level of risk to your hearing. You can make that risk very low: 22 subsonic suppressed, hollywood quiet. You can make it...
Think we were talking past each other to some extent. I agree that all those other factors are valid to prioritize, even if some aren't quantifiable. My point was that you needed to be able to know the sound performance in the first place to balance it with your other, higher priorities. All...
Understood, if you never shoot without earpro on you and the folks around you, then sound performance isn't an important criteria. It's even less important whenever the data isn't available for it. For hunting it matters to me. Do you prefer K cans?
Who said that "ALL" I care about is sound? You are strawmanning this. I care about weight and length too, but I can both already objectively and independently quantify those and manufacturers are also already honest and transparent about them. But since the whole entire point of a can is for...
Implied in your statement is that it would be ludicrous to run overly heavy or lengthy cans. Ounces and inches which we can not only measure and verify ourselves, but that vendors are by and large transparent and accurate about. Now do sound reduction. You sure a TBAC 338 is the quietest thing...
Reducing sound is literally the whole entire point of running a can instead of say a 249F. We make way too many excuses for companies who don't run their cans through Pew Science in order for us to make more informed decisions about purchases.
To know that this is incorrect you only have to have fired a pellet gun with lightweight projectiles that go supersonic. The supersonic shock wave propagates away from the shooter, and even to a bystander catching it that wouldn't be true. 140db peak meter OSHA guidance is meaningless if you...
