Is this new Bartlein barrel salvageable or toast?

[stickball]

I picked up this new Bartlein barrel from my gunsmith before he installed it on my action to have it cerakoted.
Before taking it back to the gunsmith after the cerakote was done, I ran a bore scope down the barrel and discovered this ugly scar in the chamber...looks like the reamer did the boog-a-loo. The scar is about 1/4" below the body/shoulder junction.
I should have bore scoped before I had the cerakote done...could have saved the $$.
Is this barrel toast? (.223 Rem...1/8...chambered and cut/crown to 24")

 

[Walt Krafft]

Set back and rechamber to fix it. Probably will need to cut the whole tenon off.

 

[DShortt]

That's a major chambering mistake.

 

[stickball]

Wouldn't they have to cut off more than the tenon? Wouldn't the cut have to be past the gouge...about another 1.5 inches plus the tenon?
How about the barrel profile (Remington Varmint) fitting the stock?

 

[Dolomite]

Take it back to the smith and ask him to explain that gouge in the chamber.

 

[L.Sherm]

I would take it back to the smith and have him redo it, while its definitely a gouge probably by a chip the bore scope makes it look deeper 2 or 3 turns back may clean it up

I had that occur in a chamber I cut. Nothing unusual happened during the process, and there was no damage, or chip weld on the reamer. I continued running the reamer in until it cleaned up, and then adjusted the tenon accordingly. Barrel ended up 3/4” shorter than planned, which suggests the scoring was about .003” deep.

Wow, someone needs to check their work before it leaves the shop. Hopefully it looks worse than it really is. Strange place to have a gouge, in my experience. Maybe porous metal, just thinking out loud. Good luck and keep us posted.

Proper feed and speed when chambering with a muzzle flush system using the correct coolant will prevent this. And since I started using carbide reamers Wow!!! the reamer cuts like butter.

You need a new gunsmith.

 

[Machinist John]

You need a new gunsmith.

Agreed!!!!

 

[Northridge]

Definitely “gald” as others have stated above a chip likely between reamer flute and chamber .

To the OP - before you throw the 'smith under the bus, contact them and provide images of the chamber. Give them a chance to correct it.

Everyone makes a mistake now and again. Things happen especially in busy shops. It's how a business responds to a problem that matters.

Yeah I had a smith cut a chamber crooked on me once. Tried shooting it anyhow, but accuracy could not be achieved past 1 moa. He had spun up maybe 7 or 8 other barrels for me in the past that all performed perfectly well. So I told him about the crooked cut i saw with my borescope on the lands and how I did a little testing for a load and give it a chance, but nothing showed promise. He looked at it with his bore scope to confirm, then without further question he chambered me up a brand new barrel that shoots great. Still use him for various hunting and varmint rifle projects to this day. All other work besides the one chamber has been flawless. He's a really busy man at times and sometimes isht happens. But he stood by his work and took care of me when something went wrong so he'll always have my business for that

Yep
kinda like cross-firing there those who have and the ones who have'nt YET

 

[Fuj]

That gouge looks to me like the reamer itself chipped, and that
chip got chased by the next flute or two. I like to look at my work
after the the oil is cleaned out. I also cherro cast chambers after
cutting to see what I really have. It would have been a bitch trying
to push out a casting with that error......Yep, head back to the smith
and have a chat.

^^^^^ what Walt and others have said...

your going to have to cut most or all of the tenon off and have it rechambered.

Could have been a dull reamer or the reamer is chipped or I've seen brand new reamers cut like garbage but whatever happened the reamer tore the material and didn't cut.

We are making a batch of test barrels right now.... Customer supplied the tools. For a batch of about 30 ammunition test barrels. Customer sent us two brand new carbide tools. Just feeling the tools they are not ground/sharpened properly. You can rotate the tools in your hand and the reamers won't even bite into your skin. We are setting the tools up in a chambering machine. The tailstock of that machine I kid you not must way at least 300 lbs. It has 10 tool holders/positions in the tailstock. First reamer stopped cutting shortly after starting to get to the shoulder. The throat of the reamer is smearing/not cutting and leaving a burr on every single land. Scotty tried putting more pressure on the tool... and moved the whole tailstock! Funny the reamer didn't break! 2nd reamer... no difference.

So I sent pic's to the customer... turns out they bought 10 tools all at the same time.... they went and inspected the other 8 tools in they're possession and told me... Yep all of these are all the same as well. The order was due back in Jan. but we didn't get the tools sent to us till a couple of weeks ago. Now the job is just sitting there as we are dead in the water until they get the tools reworked/replaced!

Do you have any interest in 223 AI?

I get what your getting at.... run a AI reamer into it to clean it up. That's a good thought!

That might not work... that tear looks pretty deep and even the AI reamer might not clean it up. It's possible but I wouldn't hold your breath.

The same principle would sort of apply to the 22 Nosler. It's a fair amount fatter but uses the same bolt face. You would need to set things back a little since the shoulder is in a different spot.
