Are these tooling marks unacceptable in a barrel ?

How does it shoot?
if it shoots fine, put the bore cam away and plink it up.

Bore scopes will drive you crazy the only time I use one is if I have a gun that absolutely will not shoot. If you’re just gonna go look at a barrel, you’re gonna drive yourself nuts if it shoots, don’t look at it lol.
This is the reason I don’t own one. I have plenty things to drive me crazy about my shooting.
Shoot a savage barrel
Then bore scope it
You’ll be surprised

Myself I borrow one from my friend if I need one, but it drives him nuts. He’ll call me on the phone talking about how bad they look and I’m like just shoot it if it shoots OK who cares what it looks like it could be smoothbore if it shoots good Quit worrying about it lol
Exactly! The only time I use a caliper on my reloads, is when I start blowing primers…..
As far as I can tell from the dark images, these rather ugly marks look much more like marks from chambering or crown reaming, and not from barrel production. Is this a barrel blank or a chambered barrel? Where in the barrel are these marks? (I suspect within 3/4" forward of the end of the chamber, caused by the reamer pilot, or within 3/4" of the muzzle from a crowning tool.) As has been said, if the barrel shoots and does not copper up at these marks, no issue. But if the barrel is not up to your expectations, talk to the smith first and then barrelmaker if needed.
I get that, but I like using one now and then just to keep an eye on things especially for throat erosion or carbon buildup. But yeah, if it shoots fine, probably no need to stress
A friend had a stock Remington 700 in 243. Had a factory medium heavy barrel. Damn thing shot like a laser beam. Had it bore scoped and it looked like a back country secondary road..... "the proof is on the paper"......
No truer words! Have to use those things with the right frame of mind or you’ll develop a mental illness. In the final analysis, it’s how well the metal meets the target down range that counts.
I’ve got a Savage Model 12 LRPV in .223 and the barrel looks like a corrugated drain pipe inside. Thing shoots like a laser beam as well. Just yesterday spent time at the range bouncing a 3” gong at 500 yards.
Borescopes are fantastic tools for checking your cleaning progress, as well as diagnosing an issue *after the barrel has underperformed on the range (and all other parts of the kit have been examined).
18 years ago I had a factory .223 that was a legit 5x5 half-minute rifle with a handload. I loaned it to my F-I-L in 2012, and got it back in 2019. Two years ago I tried shooting it again with the same handload, and it had opened up to a 3/4 - 7/8 MOA rifle...so I started cleaning the bore back to bare metal in hopes that the accuracy would return.
It was certainly filthy, but after ~30 patches I took my borescope to it. Holy crap, it had massive pits everywhere the last 8-10" of the bore. Obviously it had not been taken care of. I do mean everywhere...as in you would pick up at least two spots of pitting in that tiny little mirror regardless of where you were at.
Yet that barrel still shot 3/4 - 7/8 MOA with all of that damage.
It is one if the reasons why I and others will suggest shooting it before you let your borescope determine that it's a lemon *depending on application. Obviously if that is your next bench rest barrel, you have issues.

I like borescopes they are invaluable tools.
This barrel is not acceptable to me....but it's your barrel. I send those back before chambering, unless it's on a rifle, and you own it.
I will still purchase from a company that puts out a defective product, if they replace it right away, without argument. That sometimes depends on who answers the phone.
Accepting substandard work is on you, and the manufacturer never has to change their mediocre to crappy production, because the people accept it.
If I decide to use it, I lapp it before I shoot it. Then borescope it again, then sometimes lapp it again.
If you practice looking at barrels you can get a good idea if it's gonna be consistently accurate, and what to look for....it puts a smile on your face before you shoot it...cause ya know.
