The Grim, from Salmon River Solutions, Q&A

[Salmon River Solutions]

Hey everyone,

Starting a new thread dedicated to our new model of Suppressor brake, The Grim

Ask questions that you have and we (Ken or Cory) will answer them ASAP. @Cory_Shoot2Hunt @Ryan Avery

Here's our current plan for offering other brands besides the Scythe and Reaper that launch June 17th.

-Dead Air, Diligent, and TBAC Magnus
-End of July, Early August
-AB Raptor, Abel Co Theorem
-September
-HUB end cap cans
-October / November

Thanks!

Ken

I am sure there is a reason, but why don't you 3d print it and save a bunch of weight? I am assuming you can't or the cost would be too high?

 

[Okie-hunter]

I’ll be trying one when the Diligent defense model comes out.
One question I have, how quick/easy is it to change the timing once set?? If I move it from 1 rifle to another and need to adjust timing is it pretty effortless?

The cost difference between time on a lathe that costs $200,000 and a mill that cost $150,000 Vs. a 3d printer that costs $850,000 drives the 3d printed cost up too much. Standard shop rate on our equipment is like $100/hr. The 3d printers at that cost are approx $400/hr

Its very easy once you understand how the timing ring works. After we get them back from anodize Wednesday we will be filming a "how to" install video.

Appreciate the response. I figured there was an obvious reason why. Have you guys figured out a way to put values on recoil reduction % and decible increase?

Not directly. We will eventually use the recoil sled we had made. And also do some sound testing with unknown suppressors so that we can get decibel increase at shooters ear. We're guessing its about 6 decibels just from shooting them a ton.

Looking forward to it

What's the ETA for Dead Air version being released?

Do you have an elevator pitch on this product?

I may have missed the marketing materials. The website description doesn't seem to get into the "why".

The only suppressors I have with brakes on them are what comes from the factory on the Scythe Ti.

My biggest gun is a 308 juiced up with the sig fury brass to 300wsm speeds. Shooting thru an AB10 currently for flat range work, not sure if I'll take it hunting like that or not tho due to weight and length.

I would be interested in recoil reduction for that gun in particular but probably not at the cost of a big loss of sound suppression.

I'm averse to brakes on unsuppressed barrels.

 

[ACHILLES]

Which is going to have less recoil on a 9.5lb 6.5prc? us reaper with the grim brake or us nhs competition?

It's great for recoil reduction, and phenomenal at muzzle control.

We're guessing its approx 6 decibels louder when adding the Grim.

Yes, and No.

The recoil impulses are completely different.

The NHS is like shooting a muzzle brake that is 143 decibels. Its a snappy recoil.

The Grim on a can is just that, a brake on the end of a can. The recoil impulse is elongated because the gas is slowing down inside the suppressor.

In the shop we're about 50/50 on who prefers the Grim on the Reaper and who prefers the NHS.

Do these brakes perform well on lighter cartridges such as the creedmoor family? or do they excel more with heavier recoil magnum cartridges?

Sounds pretty close then. Aside from recoil impulse, which if put on a recoil sled will recoil less? I don’t care how loud the NHs competition is just looking for the least recoil. I realize if it’s close and you haven't actually measured on a recoil sled it may be hard to say for sure. I’m just looking to buy one or the other. And I would hate to buy the us nhs if the reaper with the grim actually recoiled less and was quieter.
Thanks

I prefer the NHS. *but* I shoot a decent amount of comps. If you're on the fence I would get the reaper plus the grim as its customizable.

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

The Grim brakes are tuned for something around a 6.5 or 7 PRC. Something like a 300 RUM or 300 Norma would be too much.

That being said they work phenomenally well on my bergara mg lite in 6.5 creed.

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.

Ken

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.

Difference is at shooters ear.

The goal with the Grim is staying hearing safe for *most* cartridges, and controlling recoil and muzzle rise for follow up shots. If you want something that's not as loud, it won't work as well.

And yes, that is substantially louder.

It's so insanely subjective depending on barrel length, powder type, amount of powder, terrain your in etc.

And ya I know a bit about db's after helping develop some suppressors and observing a bunch of testing.

With a good suppressor in a hunting scenario you're still hearing safe. I'm not saying someone should go shoot a can with the Grim on it at the range for 100 rounds without ear pro.
