The Grim, from Salmon River Solutions, Q&A

[wind gypsy]

6 decibels is significant. I'm not sure if you much about decibels or not but one would hope the difference isn't 6 decibels. @ that point might as well keep the barrel long and shoot a good brake.

You can add 6 dB and still be in the neighborhood of 15 dB less than a bare muzzle, much less a brake.

I'll be hunting in Alaska for blacktail with my 16" 6.5 PRC. I'll be running the 4" reaper (and possibly the HUB reflex) and the Grim brake on the gun.

I'm trying to find the optimal suppressor for my 20" 6.5 PRC. I don't love the ZG6.5 on it now. With factory stock, I'd like a bit more recoil reduction. There's a chance when I put the rifle in a RokStok, I'll no longer need extra recoil reduction. I guess I'm going to have to break down my RSS for testing since my new RokStok is delayed.

I think OTB would look great on this 20" barrel. I also like the smaller diameter of the OG6.5. I'm curious about the new Nomad OTB with Recoil X and now the offering you speak of above.

Tell me more about 4" Reaper with Hub reflex. Is this available now, if not, what does the timeline look like?
In your experience, do any of the combos I mentioned above stand out for hunting with a 20" 6.5 PRC?
-Nomad OTB w/ Recoil X
-Reaper with reflex and Grim
-OG 6.5
-Tenet w/one port Horizon

I ran the OG6.5 on the same 16" 6.5 PRC for my first bear this spring on a jet boat hunt up the salmon river.

That rifles about 8.5 lbs, I watched my trace and bullet go into the bear at 430, and watched my follow up shot also at 360. That being said, I was rock solid in a prone position, and we had a ton of time waiting for him to pop out from behind a tree. The nice thing about the OTB is that I had this gun in a folding stock, and I put it in my gun holster on my Exo pack, suppressor down. The OG only sticks 4" past my barrel, which means the bottom of my gun is 4" from the bottom of my pack, and the folded section sits just below the top of the pack. It was extremely easy for bushwhacking thru stuff to pack that bear out.

@Cory_Shoot2Hunt can answer the suppressor questions better than I can. He does sales for SRS and Unknown Suppressors.

[whoop]

looking forward to trying one out in a couple weeks, order has been placed

My recent personal experience / perspective on a suppressor brake …. Not a big performance advantage on my Creedmoor case.
Actually a negative effect. ( added Noise, & concussive effects. And a less relaxed shot )
If adding length to a suppressor on the light cartridge’s I’d opt for a baffle, or a reflex over a brake. More of a positive effect. ( slight added reduction in: recoil, noise, & concussive effects. )
And a more relaxed shot.

Others may have a different or more positive experience / preference with a suppressor brake on a creed size cartridge.

They do Look Cool

Thanks for your feedback. Which suppressor(s) and which suppressor brake(s) have you experienced this with? I think I want one for my NRL Hunter rifle, but I'm in full sponge mode trying to learn everything I can about this subject.

6 decibels is significant. I'm not sure if you much about decibels or not but one would hope the difference isn't 6 decibels. @ that point might as well keep the barrel long and shoot a good brake.

I'm hardly an expert on sound, and I don't have experience yet with suppressor brakes. Indeed, my suppressor experience is relatively limited (3 centerfire rifle cans over about 8 years, but 2 of those cans came in the last 2 years.) But I'm curious about your subjective claim that with a 6 dB one "might as well keep the barrel long ad shoot a good brake." Why?

Here's the background for my skepticism. Using the recent Outdoor Life data for convenient reference (and understanding it's not really scientific or perfect):

• Bare muzzle was 165 dBA
• Adding a Dead Air Nomad XC Ti (just for reference) reduced their measured dBA to 139.5 dBA
• Adding the Recoil X Gen 2 (again, just picked for reference) to that can increased it back up to 145.1 dBA
  • By way of reference, a Banish Backcountry metered 142.2 and Gunwerks 6IX metered 144.2
• But a CHAD or Hellfire brake increases dBA to 167-168.9 dBA

So I understand a 3 dBA increase is perceptively louder and double the sound energy. A 10 dBA increase is generally said to be perceived as twice as loud by the human brain. But if putting a well-designed suppressor brake on good, full size suppressor gets me sound reduction on-par with most of the lightweight "hunting" cans plus gives me muzzle rise control, why would I want to use a regular "good brake" that's going to be exponentially louder? What am I missing?

look bro, my comment wasn't intended to break hearts, as I'm a fan of srs products. what i meant by my comment was simply to the ear on some calibers you're still going to feel like you will want to run hearing protection if your sitting on a bench shooting 20 or so rounds on some calibers as a 6 decibel increase is significant to the ear. that's it. nothing more, nothing less. so if im at the range with muffs and a can i might as well have not cut the barrel for the can as i much prefer a short rifle and ran a brake, not lost velocity, and wear muffs. it is what it is.

I dont think you're missing anything. In my experience, even with a less effective end cap (recoil x gen 1) I still find it worthwhile addition on my 6.5x47 PRS and NRL guns which is basically akin to moderately loaded 6.5 creed. A more aggresive model like the RX g2/comp or the grim would likely be more effective yet but also a little louder.

It's not a difference like going bare muzzle to aggressive brake but it does make a difference.
