Scratched chamber

[Max_The_Phoenix]

Hi Everyone
I ran the borescope through the barrel and found out the chamber area has some scratches and raised metal marks
Tried to chamber a virgin brass and closed the bolt, extracted brass has the exact same marks

I look at the bag of first fired rounds that I saw they have the similar marks so it can’t be my mistake during cleaning and etc…


This is a custom rifle with carbon fiber proof barrel and has about 150 rounds down the tube.
I am very disappointed since it’s made by one if the best custom rifle builders in nation!
-should I worry about these scratches and are they going to affect the accuracy and consistency in load development?
How about case lifespan?

- solution to get rid of them?

- do I have to solve this issue before continuing load development?

 

[Near miss]

They are so miniscule that they are irrelevant.

Clean it properly, then with lapping compound, do not lap it, just 4 passes, one to each direction and take new pictures after that.

I do not think a well done chamber is supposed to leave case shoulders dented / harmed.

 

[spife7980]

I don’t see any scratches?

 

[FALex]

Is this a Proof barrel? If I can get this pic of my buddy's .308 after 2500rds, and knowing another buddy who had some fucked up Proof CF barrels, I'd guess it's Proof.

Do tell...

 

[smoooth1]

Did you clean and inspect your barrel and chamber before putting the first round in it?

Looks like a chip embedded in the chamber?

Edit to add: Why did you put 150 rounds through it if you were seeing questionable marks on the brass?

The tiny scratch below the shoulder (if I’m seeing what you’re seeing) isn’t going to affect accuracy or case life at all.

 

[XLR308]

Could be a small piece of carbon, i had a new die i was suspect had a finish flaw and turned out to be a carbon flake.
After identifying and cleaing the scratches in brass disapeared.

Hi Everyone
I ran the borescope through the barrel

Why?

Brass life will be determined by a few factors including whether you run your loads mild or hot, brass prep methods/practices (annealing, sizing/extent of shldr bumping, etc) and overall brass quality. The tiny scratches seen in your pics are not one of those factors.

How is the rifle shooting/grouping?

Here's my buddy's .308 Proof after 2500rds...

 

[Hecouldgoalltheway]

Here's another example of why borescopes should be illegal.

How does it shoot? If it shoots like it should, who cares. I have dies that scratch brass, I have chambers that scratch brass, but they shoot tiny little groups and it doesn't freaking matter.

I dont give two fucks about borescopes and dont own one but if i pay $250 for a set of match dies that are making deep scratches in new Lapua brass i sure as hell want to know why.
Had I not identified that there was a piece of carbon stuck in my die that might have ultimately endended up in my chamber which is a softer material than the die and made the situation worse.

Ignore those marks.
Load dev unaffected.
Brass life unaffected.
No solution required.
If you can’t sleep over it, send the pics to the manufacturer and see what they say.

You would categorize those as "deep scratches"? I think they are superficial and irrelevant. I would do nothing in this situation but shoot this rifle for its intended purpose. My 6arc dies scratch my brass worse that that. It was from using them to de-prime dirty brass before I purchased a stand alone de-primer and cleaned fully before I hit them with the dies. I'm probably on my 8th firing on hornady brass, and it is not a problem in any way.

I didnt say those were deep scratches but what i was seeing from a fairly new Redding Type S FL die were deeper than that and you could fairly easily hang your fingernail up on them.
I have been reloading a long time and had never seen it, regular contaminates such as dust and other crap yes can make small minute scratches and is normal.
Unless you are working in a highly filtered clean room intended for assembling shear seal valves or other sensitive components or electonics its going to happen but i try to minimize that as much as is reasonable.

I did not clean the barrel before chambering the first round,

-I did not pay attention to scratches on the cases since I am still learning

I am not really a good shooter but I was able to mange these groups with my handload

You're still on a brand new barrel and developing a load and shooting a .5 group.

There's nothing wrong with your rifle or chamber.

So why did you feel compelled to look at your chamber/barrel with a borescope?

Trying to understand how you got from shooting .5moa (assuming all your groups are broadly similar in size to the one in the pic) to “I need to borescope this thing”.

Like many new shooters/reloaders, you’re way over analyzing and overthinking from what you have mentioned so far…If it shoots like that, don’t bother. Its not like you’re going to be entering the rifle into some kind of “internal barrel” beauty contest…

 

[OREGUN]

Good on you for being curious. Sometimes small marks do mean something. I don’t think this is one of those times. It’s always a good idea to wipe out a new barrel and chamber to make sure there is no leftover cutting oil or chips. Otherwise, keep shooting and don’t worry about the scratches in the chamber. Nice group.

I have been saying this about calipers for years. Before that the calculator……..

For that matter, the sooner we outlaw wrist watches the better. A lot of problems started when we moved away from the abacus and church steeple clock towers….

I've been saying for years that if you're rifle is shooting well, it doesn't matter if you borescope it and a naked family of homeless people are waving back at you from inside the rifling.

Only one of us can be correct, but since the sole purpose of a rifle is to force bullets into precise repeatability, and if it is doing that correctly, the 50 people a month making posts like this are proof that even when everything is going fine, people can't keep from overthinking things. The shit reminds me of when I was a millwright in the Midwest and we would be crawling around on 70 year old grain elevators, and they couldn't stop talking about how bad all of the welds looked. I would tell them that those welds had held that thing together for 70 years of Midwestern wind, weather, and vibration. Until they could show me their 70 year old welds somewhere still kicking ass, then you have to admit that it doesn't matter what it looks like if it works. Same shit..

 

[Max_The_Phoenix]

So the other day that I was shooting for groups didn’t have my sand bags, I had some spreads up to 1.1 moa that I know it’s because of the powder charge.

But with HORNADY ELDX ammo I wasn’t able to get lower than 0.9 MOA

The builder was claiming you should get 3/8 moa with factory match ammo which isn’t the case.
I think it’s just a bold claim!

Looks like they built you a nice, well-shooting rifle.

“Accuracy guarantees” are retarded and if I was building rifles, i’d never quote one. Too many uncontrollable variables once the rifle leaves the shop that influence performance beyond the platform itself (mostly to do with varying shooter abilities and ammo quality, as you have seen).

I still would love to know how your mind went from “rifle shoots .5 moa; groups nicely or when it doesnt, I know why” to “i have to borescope this rifle”. The thought process makes no sense.

Tell me about it. I have been waiting nearly a year for PTG to get their shit together and provide Stiller acceptable bolts for their Mk13 actions….eventually they will (hopefully) and ill get to finally finish my mk13 mod 7. I don’t even want to know how much ill be into it once all said and done.

That said, you also have to make a judgment call on what’s truely an imperfection that could affect your rifle’s safety and/or performance and what isnt and those scratches are nothing to worry about. As long as it shoots and doesn’t exhibit any indications that it’s not safe to operate, you’re gtg. Lots of folks get wrapped around the axle with what they see when they look at their rifles w/bore scopes. I use them if something’s obviously wrong based on observations during or after shooting but aside from that, i don’t bother.

That’s a nice looking rifle, congrats.

It surprises me that Altus gave you an accuracy guarantee (or at least expectation) as there is so much that goes into determining downrange precision.

I have an Ern (@AccuSol-ERN is the Altus gunsmith) built BA and wow, I stuck a bore scope in it when new and was very impressed with the cleanliness of the chambering job and I'm very happy with Ern, Al, and Altus overall.

Personally, I wouldn't get too worried about superficial scratches in the case body at this point...particularly since you didn't clean the chamber yet (or at least before firing). I would clean it very well and see if you still get these scratches.

I would be thinking more about what looks like dents in the edge of the shoulders where it needs the body. Its very hard to tell from a pic just how egregious these are....did this brass hit the ground at the range or.....??

I did clean the chamber
Yes bras hit the ground.
And I even chambered a virgin brass in there and still got the same scratches, I will check a few more cases and see if they have a dent on the shoulder and will update you

Thanks....not sure what's up with the scratches but you can always contact Altus, tell them what you have going on and send them some pics, and see what they say.

As for hitting the ground....that seems like its a very strong possibility as to where the dents in the shoulder/body junction came from.

Cheers

Hello everyone.

To start, I would like to thank everyone for helping out Mr. Fereydani as he deep dives into the realm of precision rifle.

Now let's get down to business. I can assure you the chamber did not leave my shop with anything short of a pristine 400grit polish (some even argue TOO polished). So we need to figure out why the scratches are there. I am thinking reloading practices on used brass (dirty brass, dirty sizing die, etc.). I have seen dirty brass mixed with case lube create a substance that rivals the best valve lapping compound. Unfortunately, this compound can very easily etch/dull/scratch the chamber surface finish quite easily and in short order. What goes for the chamber......also goes for the sizing die.

I recommend doing a superb cleaning of your sizing die. Then run a new piece of well lubed brass through. You may not get full contact on new brass......but hopefully it will be enough to catch scratches if it is the culprit.

Same goes for your rifle. Clean the chamber like you have never cleaned before and then dry it completely. If you can, shoot new ammo on a very clean chamber and look for scratches. If you are shooting reloads, make sure ALL case lube is off the round. I like using acetone to get every bit of lube off.

If the scratches still persist, they may very well be in the chamber now and can be polished back out.....depending on the severity. If this is the case please contact Altus Shooting office phone or email for further instructions.

Regarding accuracy guarantees. I can assure you, nobody would drop an accuracy guarantee quicker than me, if it didn't affect customer sales. Accuracy guarantees sell rifles like horsepower numbers sell sports cars. I absolutely hate giving a guarantee on something I didn't machine 100% from action to muzzlebrake. That is also why I am picky about using top tier parts......not saying they are perfect.....but I am hopefully mimimizing the chance of an errant part and an unhappy customer.

I have built a number of prefits, B/As, and rifles that shoot in the .1s and.2s.

I have also built 338winmag (and like cartridges) hunting rifles the customer had to diligently work up a petload using a specific hunting bullet of his choice.

I wish all barrels were perfect, all bullets were match accurate, all dies were perfect, and all reloaders/shooters were experts in their craft. Unfortunately, this is not reality.

Please keep this thread updated with what you find/decide.

Hi Ern
Thanks for your reply

I still have the cases from the first firing session and didn’t reload them and they have the same scratches

Also for my reloads
I never insert a dirty case in my sizing die or chamber, i do decap, tumble and start my measurements stuff…

I will share the info with Altus tomorrow.

Sounds good. I look forward to getting to the bottom of the cause.

Thanks for taking the time to write this great reply.

As I said, I did scope out my BA you did for me…you guys had the action and trigger and I sent a Bartlein blank down) and it was pristine. Everything symmetrical, even, polished…just square plumb and true in every way I can see. Shoots great and I’m an ecstatically please Altus customer.

And I’m w you about precision guarantees. My rifles are better than me and I’m sure many others. It just seems like an invitation for dispute if the owner can’t shoot it to its potential. I think Mike at TacOps is smart sending out test targets w his guns to show that the gun could do it so look in the mirror if it doesn’t for you..haha.

I forgot about his dies. I just ran into this where some copper fouling got stuck in the neck area of my die (and yeah, I lube like crazy..this was from once fired Lapua brass) and left little scores on the necks of my cases (which will shoot out next time). I couldn’t see any fouling in the die until I bore scoped it. Some copper solvent got it out then I chucked a bore mop in a drill and went to work a bit w some semi-chrome. Dunno why I’m boring you all with this! Lol.

@Mahziar Fereydani , were these virgin cases or once fired as factory ammo. Just wondering (and you may have stated this above but I’m old and have bad CRS) if these scratches were there immediately after first firing or if they showed up on brass after you hand loaded it).

I need to log out now, I think! Before I type more stupid shit Lol

The barrel is proof research CF 1:7.5 24”
Sandero light, didn’t put it on the scale but should weighs less than 9 lbs including scope, it feels like a feather.

I used to shoot every rifle, then customers complained about receiving a "used" rifle. When rifles shot great with my ammo or reloads, it never failed, the customer wanted to shoot a different ammo or load recipe......so in their eyes.....the accuracy proofing didn't mean anything.

The above coupled with range time and ammo (or components) is why I gave it up. I still offer it as a service but you are going to pay for it. It is hard enough staying on top of leadtimes without working 7 days a week. I am a one man show, no cheap employees or assembly line stuff here.

This is a legit scratch (all me. smith was not the cause of this)

This is how it shoots with garbage Hornady. 2, 5 shot groups.

“Cold bore” on the top one, my fault on the bottom one.

All courtesy bad seating die and me being short on time and rushing things… it’ll be a tomato stake in a year or so… shoot it, toss it, get a new one.

Yer buddy needs to work on his fundamentals.

Being the former number 2 tac rifle shooter in the nation in the PRS, a sponsored shooter by one of the most respected shops in this community, and a former USMC SS, I'd venture to guess that you're fucking incorrect.

Are you saying the barrel is shot out at 2500 rounds? 300 yard groups?
