Suppressed and Dirty Bolt Face?

[General RE LEE]

Banish Backcountry can, Tikka 6.5 CM, 41.5 grains H4350 143 ELDX, shot this load for 2000 rounds on this bore. Tight primer pockets no pierced primers.

I occasionally get a dirty case head and my bolt face gets really dirty when shooting a string suppressed. Is this caused by a dirty can?

 

[Supersubes]

Possible some crap from the suppressor fell down the bore when uprighting the gun(in a gun rack for example). Or while installing the can.

I place the gun on the rack upright between strings.

Thats probably all thats happening. If you havent cleaned in a long while, give it a go.

Never have cleaned it. Has probably 2-3K rounds through it.

Its time.

Yeah, I had chunks of carbon falling into the bore after thousands of rounds. I’m sure that’s not good for the bore if a bullet smashes over some hard-ass chunks.

Agreed, although this 20” Tikka CTR 6.5 CM bore still going strong at 2200 rounds.

 

[General RE LEE]

I soaked in CLR for a few hours and rinsed it out. Chunks of carbon came out. I decided for round 2 to try Wipe Out foaming cleaner. Anyone try this?

Clr soaking will run circles around wipeout in cleaning a can

I was concerned CLR damaging the stainless steel threads of my titanium can so I rinsed it out after a few hours. Is this concern unfounded?

It would take forever to erode the stainless enough to be an issue.

One thing Ive taken too is putting the can in a vice and getting a dull awl and tapping on the carbon in the blast chamber and end chamber if you can. Some light hammer taps on the awl will have that carbon chipping out quick, wear eye protection. For that I would be careful on the threads.

Will CLR damage powder coating on my can?

No idea. But powder coated? Is it a fence?

What can do you have? It isn't powder coated.

Banish Backcountry

How long are you guys soaking in CLR? I soaked one of mine that had carbon chunks falling out for 8 hrs and the liquid was just as clean coming out as going in?

The coating is cerakote, and the clr wont hurt it.

I do mine for 24 hrs, and agitate it periodically.

Sonic, bucket, or ear plug in the bottom? My earplug was basically dissolved when I dumped out the CLR.

Red solo cup, Ear plug. Havent had it dissolve.

 

[carbonbased]

They sell silicone “corks” on Amazon. Too tired to find the link.

 

[spife7980]

Ear plugs always seemed too porous in my imaginings, I use a rubber plug you get in sticks of copper pipe
1/4, 5/16, 3/8 whatever fits best for the end cap caliber.

 

[General RE LEE]

Well I thought the can was fully dry. Tapped it a bunch and blew a bunch of compressed air through it. Screwed it on my rifle and put it back in safe muzzle up.

This morning I pulled my rifle and checked bolt face. Evidently there was some trapped liquid that got in my bore and bolt face. Ran some patches but lesson learned. Shoot it several times after cleaning before storing muzzle up.

Yeah, I’ve read that it’s potentially bad to store rifles with the can attached (whatever the position).

Something about carbon absorbing moisture and over time corroding the bore. Potentially.

So even with SS barrels I reluctantly take the can off. With a carbon steel barrel, definitely do it.

Just an fyi.

I can see that being a consideration.

Huxwrx suppressor sauce works great to for soaking entire can without harming anything.

Earplugs hold liquid is a suppressor just fine.

 

[mark5pt56]

I removed the Keymo of the Sandman S, 3/8" plug from the hardware store, filled with clr, placed into a glass jar, filled that with water and then the tub of the US, three cycles of 30m each. Rinse in between cycles with cold water, the clr was filthy each time. I did the whole can the first cycle in a bag with clr and the finish was kind of soft, I bet the second cycle would've removed it.

There are a few different types of ear plugs. My experience has been that the orange foam plugs will slowly leak. Maybe flanged rubber ear plugs work better for this? Idk, they don’t work well for me as ear plugs, so I don’t buy them.

If you (impersonal you, not @supercorndogs specifically) do decide to to use an ear plug as a suppressor plug, “secondary containment” can help you avoid a mess.

Mine did drip a little.
