SilencerCo Scythe Ti failures

[jbwright]

This is just the information I pulled together from this thread...trying to go through at least 1 more thread that has noted failures on RS to pull that in, too, and also going on the hide, reddit, etc. to see if there's similar information on this can specifically. It's a little spotty in the sense we don't have complete data for each failure, and anywhere there are blanks, the information wasn't provided.

Oh, and the poll currently denotes 10 failures, but the last person had 2...so I noted them on 2 separate lines as they were 2 failures.

@wind gypsy was on to the theme from this thread....the failures appear to be tilted to magnums around 20"

This is about the most idiotic thing ever. Nowhere on their website or manual does it say that.

Edit: the scythe manual states this:

SilencerCo does not cover damage to the silencer
or host firearm resulting from improper “hand-
loaded, reloaded, previously used or otherwise
defective ammunition.”

However, that's very different than what you were told on the phone.

See edit. If they're saying no barrel length restrictions up to 300rum..... I think you'd have to have a massively over pressured hand load to equal the exit pressure of say, a factory 16" 300 prc or rum, which according to them is fine. But a hand load within published load book values is not.

 

[HighUintas]

And to point out an earlier discussion of putting the can back on the same gun.... I wouldn't. The injury could be very bad from that extra recoil. I am actually worried about the chance mine goes even though they would fix it quickly

 

[ScienceNerd]

8.5 % failure rate, must be something wrong, to add some data my first failure #10 on your list was at about 400 rounds,

Yeah but the outliers if 6 ARC and 6.5C are really weird. Those are low pressure rounds in comparison. I must have missed those.

Not surprised by magnums

 

[ScienceNerd]

I think for the sake of science and to test just how unlucky I am, I might have to change nothing and continue with the fixed up can when I get it back. Need to mail it to them first!

 

[waspocrew]

The 6 ARC seems super odd - especially with a 20” barrel. Curious to know if that was all it had been shot with or just happened to fail while on that rifle (after being used on magnums for example).

If you do, maybe consider factory ammo so they have no excuse if it happens a third time.

Go science! Be careful!

The number of failures on smaller cartridges like 6.5 cm and 6 arc makes me think that it isn't a problem with bigger magnums specifically, but a problem with consistency of build. I.E. if you get a supressor that has sufficiently sub par strength in a weld zone, you may be able to cause a failure under relatively gentle conditions. I imagine that for a can that perfectly met the design specs, we would see very few failures for any of the conditions in our table. It is also worth nothing that most failures happened after more than 100 shots, this means it is at least a fatigue problem on some level rather than a straight up insufficient strenth problem. That is to say, that it takes a number of loading cycles for the area with low strength to develop and propogate a failure fracture that leads to separation of supressor baffles.

I am thinking that maybe Dead Air Nomad Ti XC or TBAC Ultra 5/7 is the way to go. Any others have thoughts on an alternative?

Sad part is that the recoil reduction and lightweight of these cans is excellent, IMO. I can really tell the differnence shooting this rifle without the can on. I don't think the ones I have mentioned above will have as good of recoil reduction.

 

[jbwright]

separate cans on separate guns

@Longshot406 can you give us the deets on both failures? Cartridge (I believe you had 300 PRC)/est # rounds barrel length (I think you said 22"?) factory or handload etc

Fair, and I know that Dead Air has issues, I think the Ti XC is a new design from them. I am wanting to see if people have alternatives, those were just some I came across, no you have some alternative suggestions? I have seen the AB Raptors that I hadn't come across till this morning.

OCL and Diligent Defense are two others. For me, it's not so much that DA had those failures, it's that much like with the scythe, they did a terrible job of acknowledging and owning them. Their new stuff might be fine, and I may end up with another DA can at some point, but watching the past issues unfold makes me a bit hesitant.

These I speak about I have, I use in ear molded ear pro while shooting but not muffs if suppressed. I dont use ear pro hunting with suppressors unless i have time like in a deer stand.

Ultra 5 gen 2 doesnt have enough sound suppression. Its mounted with a Cb brake on my 6.5 gaymoor fieldcraft as weight was the most important thing to me there not total DB. 5.96 oz can and 3.10 oz brake.

Ultra 9 gen 2 is a giant dong. Long and heavy but very quiet. I havent found a suitable place for it. Its currently on a ar10 but it runs bad due to the amount of backpressure created by the can. 11.96 oz

Ultra 7 gen 1 is goldilocks. 11.64 oz I think the gen 2 are lighter.

Scythe is goldilocks. Mine hasnt blown up. 8.32 oz with 1 port brake.

Diligent defense enticer ti short is very close to the ulra 7 IMO. Although I dont have hundered of rounds through it yet. 8.75 oz

Raptor 6 with 5" bull relex is very good and works well on my 24" barrels on my super mags. 257 blackbird, 300 win and 300 prc. However its heavy and that gun is a boat paddle with it on. The balance isnt great and its more due to the 24" barrel. I dislike that the can is ribbed for ear pleasure. 13.93 oz for the size isnt bad at all.

Deadair sandman ti is again a giant heavy dong. Its on my 300 BO SBR inside the hand guard and make it really quiet for depredation with subs. 19.5 oz is stupid heavy but it is full auto rated.

2/20/25 update on the Failures noted (that I could find) on RS

I'm messaging some of y'all if you had a failure to try to fill in at least the # rounds and ammunition details (it looks like at least have caliber for all of them, so that's a start I guess). All good if you wanna be left alone but if you want your data included PM me or reply here and I'll update the information. This data is what I could find from posts posted on Rokslide. There was another thread I was able to locate 1 additional failure (from the information I posted yesterday). Some of those in this thread posted there too, but didn't update the sheet as they would've been duplicates.

Edit: Updated chart to indicate in "Notes" column the caliber shot when failure occurred (my deduction, if inaccurate feel free to correct)

Edit: I've been able to locate a few others NOT ON RS who have had failures but don't have the same data to include here, and really don't have solid information/credibility (or a way to contact) to reliably include them here.

 

[jbwright]

Shot ~300 rds 6.5 PRC 18” barrel and ~300 rds 300 WSM 19” barrel. Had to pay return shipping. It appears just as new now that I have it back. No questions asked by them.

did yours fail on the 6.5 or WSM?

Where are you seeing failures on 6 arc and 6.5 creedmoor? I think people who listed those had them fail while shooting a larger cartridge but just listed the smaller ones as part of the overall round count on the can.

Ah, the table I was looking at didn't have as much of the "notes" column filled out. I can see now that they are failing on the large cartidges. Thanks for catching.
