What is the highest decibel reduction suppressor for 6.5 Creedmoor? I am thinking about getting one but am completely confused which one has the best performance.

I’m not hung up on it being an actual 6.5mm suppressor, .30 is fine, I’m just looking for the most objectively effective.

You worried about length? What’s the use of the rifle?

Now you are moving the goal post. I would pick the suppressor for your application. "Quietest" suppressor would actually be lower on my list of what I would want in a suppressor. Most of them are going to be decently quiet. It's hard to tell a lot of suppressors apart, and there is a lot of tonal differences in them as well. Meter numbers are not the end all be all when picking a suppressor.
 
I gotta second that TBAC .338 Ultra.
Shot next to a guy running one in a 6.5 Creed at the last match and it was just ridiculously quiet.
Not cheap, but if you want quiet-est…..
I couldn't muster the extra $$ myself, but it is super quiet. One match last year I noticed in my squad, one guy's can was the most soft muffled "puff" and asked him what it was. Yes TBAC.

Yup that’s why I asked him the questions I did instead of screaming out suppressor names. People get hung up on “quietest” as the most important. It’s not.

How "quiet" a suppressor is super low on my priorities list in picking a suppressor. Most of the comparable suppressors sound close to the same. After application, quality and customer service/product support ranks the highest.
 
Fuck PTR, get anything else at this point.

Can't go wrong with most cans on the market, but I like big volume cans for 99% of my shooting where size/weight isn't much of a concern. Sitting next to someone running 6.5cm through a TBAC338 vs. Banish 30 is more comfortable, and the recoil impulse of the TBAC338 gives you a nice warm fuzzy feeling.

Now if you aren't sure if "quietest" is what you should be concerned about, know that people underestimate the difference of an extra 8-12+ oz on the end of a lever when moving quickly.. And when you are swinging that sword trying to get into positions quickly, the added diameter also becomes a lot more of a factor.

I still vote TBAC338 personally, but I dont know if its actually the best option for OP.

Not sure what your beef is with PTR but they seem to have great suppressors.
 
PTR is currently sending C&Ds to other manufactures claiming they own the patent on 3d printing as a manufacturing process of suppressors.
Would be interesting if they actually have a patent to know what exactly the principle says. The purpose of a C&D is not normally to shut them down but to sell licenses and to maintain their ownership of the patent. My concern would be how broad they cast their net in the patent and what it’s real scope is.

Don’t know if it’s the quietest, but at 127Dba, it’s good. I have one on order.

They do, but so do enough other manufactures that I will take my money elsewhere until their C&D drama is clarified.

 
Here's a link to suppressor testing that TBAC did last year. There are a couple other organizations who have also published testing data. If you're running a gas gun, there is more to be concerned about than just noise reduction.

When I spoke to Zak, I mentioned I was interested in the shooter’s ear number only.

He said to sort by the raw SE dB (shooter’s ear) column. The dBA column is A-weighted, which is some theoretical estimate on how the human ear works. He suggested to just go by the raw numbers.

Going by that (and 308) then the Otter Creek Hydrogen L is the winner. I bought that and the TBAC Magnus full size. The stouter Magnus is for my 22-250 bolt gun for higher-volume pdog shooting (also for my AR15) and the Hydrogen L is for a walk-around or lower volume bolt gun. Both are 308 versions as there is a chance I will shoot a 30cal through them, and any 6.5 version prob wouldn’t knock down the dB enough to matter.

Can’t tell the difference with ear pro. Which you should be wearing due to the sonic crack.
 
Otter Creek Hydrogen L is the best sounding I've heard so far. Personally, I have a CAT ODB Ti but I needed a flow through because I shoot gas guns wrong-handed.
The CAT ODB is a flow through. I have one ODB and 2 AlleyCAT 762s. I have used all three on 300blk and 556 both adjustable and fixed gas blocks without issue. I am sure the Hydrogen works great but so will the CAT

Correct. Still get some gas in the face when shooting fast but it is minimal. My ODB is not as quiet as my friends hydrogen l, or other friends high BP cans, but that's the trade off I took.

I have AGB on all my guns, they are definitely worth it. CAT TI flash suppression is great after about 100 rds. It was very flashy when new.

Couple others have said it and alluded to it, TBH whatever large 338 can you feel comfortable with on budget/attachment methods will get you where you need to be.

If you are going to a public range and/or shooting around others who are, hearing pro is still going to be needed regardless.

If you are solo shooting, shooter's experience vs non-shooter experience can be quite different.

I regularly run a TBAC 338 on my 6.5creed on a 24" barrel and its a lot of fun.

I will 2nd this. I also have 2 Tbac 338 ultra RR’s and they are extremely similar to the non RR. I primarily shoot on my own property but I took it out to a range a couple weeks ago and shot it in wide open area and it was comically quiet a whole bunch of people came over wondering what the hell I was shooting.
 
Put the cat Johnny law on your list. I have a 338 ultra gen 2 and I think the Johnny law is even quieter. Their website is aids but they make good stuff.
Yeah the JL is sick quiet. I love mine so very much. I also have a CAT BBK waiting to certify it is a BIG .338 Suppressor, supposedly quieter than the JL on a 308.

Never heard of them. But wow, that is an interesting website. Why do I get the feeling that they should have Primus playing in the background as soon as the browser loads the website…? Lmfao

I might have to buy one just to know how quiet we’re really talkin

They really are a cool group. I have had conversations with several of them. What is also cool is that they support a few other up and starting companies getting into business and yeah they use really weird names but they make really great suppressors!

The Vent 1 looks really interesting, I actually have one on it's way to my SOT
I have Vent 1 and 3. They're both fantastic on .556. AR's with minimal gas. I've put about 50 rounds of a .308 and 7mm-08 bolt gun on the Vent 1 and really like it. It's as good or better than Scico Scythe TI and Magnus S. Hard for me to tell much difference in them, other than tone.
 
I have a few KRG, older SIG, and Dead Air.

The only can I've ever shot that was noticeably louder was the TBAC ultra 5. However, that's too be expected and it's on an ultra lite hunting rifle.

I still use my SIG for matches because it's quiet and full auto rated. On the light side (15oz) when I bought it 7 or 8 years ago, but tech has come a long way. Back then the ti version was still 12oz and double the price. First can I bought so I went cheaper not knowing any better.

The krg's are ti, and they're much nicer on the hunting rifles so that's where they tend to live. Same with the dead air.

I quit worrying about sound and started buying less weight. The silencer co skythe is next on my list for the light weight.

You mean kgm instead of krg?
 
I believe the Nomad L, ecco machine, and banish gold are up there pretty high on the db reduction list for 308.

It depends what you are using it for, but I believe the max muzzle reduction is useful for hunting coyotes if doubles or triples are coming in. When running a banish gold vs nosler suppressor on my 5.56 AR thermal rig, the nosler has better shooter ear suppression to me, however I noticed the 2nd coyote tends to run when the first is shot due to a louder muzzle sound vs the banish.
