Weird Dents In New Lapua 6BR Cases

[Allen Corneau]

Is everyone receiving these in the new production cardboard packaging or in the older plastic boxes? I've had some .308 Palma newer production that was very good and just opened a plastic box of 260 Remington and have 101 cases that are all good.

Mine was the dark blue plastic box.

Too much lube. Just shoot them and the dents will be blown out.

How’s it too much lube when these defects came from factory new brass?

 

[DShortt]

That's a hot mess. Given the cost, I'd be 'agitated'.

Like I said the 1st f'n time shoot'm!! I really don't need a long drawn out explanation of what you or anyone else would do, or who's doing it.
They're compression buckles in the shoulders....
So shoot'm and they'll straighten out!!
Don't most custom die manufacturers recommend 3x fired to make custom dies?
And this is fresh brass??
F'kn shoot'm! And quit bitch'n bout it!!
I made a simple statement to the problem of failed quality to a product that everyone raves about, when the reality is be grateful you got it to begin with.

Fk'n fire me if you want to!

OK. You're FIRED!

Kracken, Go to YouTube and look up manufacturing rifle brass. You will see that there is indeed lots of lube when they form the shoulders. Then they wash the cases and anneal one more time before packaging. It's really a common sense process, if a person has any mechanical ability at all.
I hope everyone understands that the process cleans the brass and then lastly anneals it.

Folks, these aren't just dents in the brass, they're creases and folds introduced during the shoulder/neck forming process.

Here's what it looks like from the inside with a borescope. The gray in the mirror is the shoulder, the brass at the top is the neck.

Just got a box of Lapua PRC brass the other day. 101 pieces in the box (and all perfect).
Just saying…

If it was a dent,i would fire them but those aren't dents. I would bet on those splitting everytime.

Because that is what usually causes dents like that on the shoulder. The factory also uses lube to shape their cases. It's likely that they were using too much lube/pressure on a batch of cases.

Those are pretty excessive but thats usually what they look like in my experience.

Did you even look at the pic in post 67?

I've pulled harder creases out of sheet metal, I'm still thinking these creases can be walked out.

How’s about Bondo?

I've fired Lapua 6 BR cases before with a much less severe crease than the ones shown by the OP.
They don't disappear, they become a line on the shoulder where the crease folds over itself

I had some 338lm brass (gwt brand) with that same deep forming fold. I fired one, it didnt iron out.

There you go, the affected case was fired, and it didn't iron out. Did he say it fractured? Did he say it flame cut the chamber? Did it put his eye out?
The bore scope picture didn't show me anything, except that he has a borescope.
Show me a pic of the fired case, not the hyperbole.

Did they split?
It's just a curiosity thing to me.
I mean we are talking about a whole whopping $3.00 in brass

And once the case is fired several times that line will separate. No hear say but fact. That is why it is best not to continue to fire them.

Most, not all, of these kind of marks we’re discussing here that I’ve seen are more like a cut than a dent with each side of the triangle a clear cut/crack clear through the wall of the shoulder.

Here is a Nosler 6.5 Creedmoor case with the crease still visible and then a shot of the inside of the shoulder, both pics after once fired to see what happened

Thank you, curiosity satisfied
