Suppressor= YES. Flashlights=NO. Just my $0.02............
Flashlight on a long range rifle?
Too bad we can't own a suppressor. I have a friend who will let me shoot on her property (about 500 yds), but my Win Mag would disturb the neighbours.
Can you tell us how loud, Db wise, it is? I've always been curious how much difference a can makes on a large caliber gun like this.
If you have an Iphone, there are some good apps for measuring Db levels.
Also, how's the recoil difference with the can and without? Or accuracy for that matter and point of impact.

The title of this post is a bit misleading. That is NOT a Surefire Suppressor. The suppressor was in fact built in Canada.
That particular can metered 139 dB on a 338 Lapua. The limit for hearing damage is 140 dB meaning that suppressor is safe to shoot without hearing protection. It is a very cool experience to stand next to a big 338 Lapua rifle without hearing protection and not have your ears blown out.
You deserve to be BEATEN for that comment.
In no way can an iphone sound meter come anywhere close to measuring a suppressed rifle. In order to capture the extremely short yet sharp muzzle signature of a suppressed rifle, a very expensive and specialized sound meter is required.
A suppressor reduces recoil about the same as a good muzzle brake. Well designed and properly mounted suppressors tend to increase accuracy.
FWIW I designed and built the suppressor in these pics.
It was originally designed to fit the CF Timberwolf.

It is a patented baffle that somewhat resembles a slant baffle but it is much more efficient than a simple slant. We only need to use 4 -5 baffles to get world class sound reduction.
Suputin - sorry for any confusion my description may have caused, the suppressor is your creation and Canadian made at that, for those that are wondering about the Surefire lights - they are mounted on agency rifles and provide both white/IR light.

No problem. I was just looking at the first pics and thinking to myself, "That doesn't look like a Surefire can." Then a few pics later I am thinking, "That weld pattern looks kinda like mine" ....... then near the end of the pics, "Thats cause it IS mine.
"It was kind of fun to see my creation like that.
Have you actually shot it or just seen the pics? It is amazing to shoot. We are so used to a huge boom and concussion from big cartridges like the Lapua but it is such a pussycat with the can on. It is very cool to experience.

You crack me up. 139db vs 140db. This isn't like calculating earthquakes in that 1db more is like 100times more sound is it? Since I don't know, do tell.
As db testing equipment, since you have the 'expensive' equipment, and you
make silencers, hopefully you have an Iphone, I'd be curious to know how your equipment does in comparison to a simple Iphone app. I'm not, for a second, saying a simple app will give you the information that an expensive db machine will, but comparing them both and enlightening us would be helpful.
Also, without a can, what is the db rating of this gun since you built the can?
1 dB is not significant here except that it shows the can is BELOW the limit for hearing damage. It could be 0.5 dB or 2 dB and that wouldn't make much difference overall except that the can is BELOW the limit which the only really important bit of information here.
Try to pay closer attention to the discussion.
No it wouldn't and no I won't. The iphone is nowhere near fast enough to be able to capture anything close to the entirety of the pressure peak. The ipone will be in the range of several thousand times too slow to capture the maximum peak which means it will capture the noise on the downside of the pressure impulse. The time duration of the peak can vary from suppressor to suppressor and ammo to ammo so there is no way to extrapolate data collected from an inappropriate source.
It would be like trying to measure the top speed of a Ferrari with a bicycle speedometer.
If a cheap device like an iphone did work or the data could be extrapolated accurately don't you think there would be professionals using it? Had it not occured that there would be no point in spending $5000 to $10,000 on sound metering equipment if a simple iphone could do the job? Yet all the professionals testing silencers do spend that kind of money. Using simple logic could have answer that question.
It will depend on the muzzle device but 338 Lapua can exceed 170 dB.
FWIW why don't you tell us how long you have been designing and building silencers as you seem to have an opinion on the subject?

Quite possibly the Iphone is a cheap device for measuring db levels and if anyone would ever put it to the test they might be surprised or maybe not. After all, I have an app on my phone that allows me to see exactly where star constilations are and tons of info about each star in the galaxie while you might get an anal retentive purest that figures the only way to look at the night sky is to use a telescope.
I'm just bringing up points and questions regarding suppressors. I don't build them or test them like you but arrogance and
isn't really a welcome sight on this forum. I'm just calling a spade a spade.
Unless you an find an app to make a 150 millisecond microphone react 2000 times faster then the iphone isn't gonna cut it. On top of that the iphone software incorporates automatic gain reduction in order to protect the system from excess noise peaks.
You may be able to turn off the protective software but you can't turn a cheapo microphone into an expensive calibrated free field microphone specifically designed for capturing impulse noise can you? This discussion has EVERYTHING to do with the design and construction of the microphone and its ability to react to a noise front passing over it.
Really? So this post by you was just an honest question and not dripping with sarcasm?
The funny thing is that I get to work with these devices all the time and you will never get to use one. What you drool over I consider everyday objects. I believe Charlie Sheen said it best ...... WINNING!
You are free to make like a jerkoff and act all Mr Knowitall about a subject on which you don't know $hit or you can actually listen and learn something. The choice is yours.
I am done with this particular waste of my time.
