New Barrel Throat Finish, Rifling damage- is this Normal?
- Thread starter ucsfl05
- Start date
The throat doesn't concern me at all, it looks uniform. The crown it self is undamaged. The bit of the rifling before would not really concern me to start, but would be something to think about if it doesn't shoot. Barrels looking way worse than that shoot good. So I would shoot it.
If you want to see something miraculous,
Shoot a savage
Then bore scope that savage
You’ll learn something about minor imperfections
The only time I could see an issue arising is when the bore is cleaned completely down to bare metal. Even then it will likely perform well

I would shoot it first for sure but if it bothers you Id ask the the builder and see what they say. I'm sure barrel builders and gunsmiths hate the invention of cheap useable borescopes.
I don't think it looks horrible and I'm sure it will shoot fine, but I also think a barrel that your paying a premium for shouldn't have those marks inside. I have a Muellerworks barrel thats worse than that, shoots exceptionally well but it holds more copper than my other brux, bartlein, and proof barrels that have a better interior finish. I have to clean it about 2X as much to keep the accuracy in line or it coppers up. I hate cleaning rifles so I kick myself everytime I didn't send it back. Everybody makes a turd once in awhile.

The true test isn’t how pretty it is, it’s how it shoots!
Unless coffee table glamour shots are your priority.

Unless you got a steal on it, send it back. I wouldn't accept that sort of machining from a top tier maker. It may or may not shoot well, but these issues will always be in the back of your mind and you will blame it (right or wrong) for any issues. It will always F*ck with your head.
Just saying.
LMFAO
Not to mention "not minor" imperfections
I own a few, including a .338 LM...the lands all look like fucking railroad tracks from the rifling button, copper foul like a bitch when new.
All shoot no worse than 3/4 minute.
I concur nothing to see here with the OP's bore, not sure what the gripe is about concerning the throat.
Throw away the bore scope and SHOOT the barrel…
I totally understand that borescopes are the bane of existence. What bugs me is the dents from the range rod used for indicating. They are so close to the crown that effectively, at projectile velocity, it may be *like* a damaged crown. I will shoot the barrel and provide a range report.
The parts shown in the pictures in the OP. I'd probably let the chamber slide, as that would have little effect on the barrel's performance. But the big nicks to me are unacceptable. If it were sold as a "blem", maybe. I've had a lot of precision barrels and I don't buy that that is a normal part of the process. It was an "ooops" somewhere. As I said though, I fully admit that it could have zero factor on barrel's performance, but it could. And that will always be in the shooter's psyche. I'm going through this exact thing with a shooting partner that was/is convinced some similar stuff in a brand new high end precision barrel is the cause of it shooting like crap more often that it shoots well, and this is not his first rodeo.
However, I don't think anyone of us would accept a cosmetic mar like on the exterior of a barrel they paid full price for and would send it back before the UPS truck even left the block. And that certainly wouldn't affect performance in the slightest. My point here is not the affect the machining may or may not have on how well it shoots. It's about the notion that if you are paying MORE for something that is supposedly a top tier product, you expect the level of finish to be consistent with the expectations that come with those $$ spent, especially as I don't think that is the norm for finished barrels in this category.
Now if that were the normal thing to expect and all or most barrels come that way and they shoot just fine, then sure. I'd tell the OP to stop whining. But I don't believe that to be the case. However, I'm more than happy to be proven wrong if the several top end barrel guys here on SH tell me I'm wrong. I don't in anyway claim to be an expert on the manufacturing process. I am however an experienced consumer of these products and I don't recall ever seeing anything that egregious.vv
A mar on the outside, that might make stress risers and make the barrel pontiguous. Cant have that no sir...
I would contact whomever finished the barrel before I shot it to let them know I have concerns about the conditions that I'm seeing. It may in fact shoot just fine but the odds have increased that it will not. Let them make the call on shooting it. Because if it doesn't shoot it's going to get dropped in there lap and the customer is not going to be happy. He will also tell his 10 best friend and about 600 people on the internet all about it.
Yes, I do. Hence my use of a comparator. Maybe better place for this would be for the 6gt threads? Would love a dimension drawing for the cartridge- this seems way more free bore than .170 (alpha makes 2 reamers, .120 and .170).
