6BR Dented Case

[JackTheRipper]

Hi Guys,

I'm having some trouble here, i'm reloading my 6BR BenchRest Savage some Lapua Brass with Berger Bullets but i'm getting some problems with the Brass.
Some of the brass is leaving the chamber with some dented marks on the neck, like the picture shows.

The brass is new

What do you think??

A bugger in the chamber.
Check the chamber for a piece of debris......like squished powder kernel or something along those lines.
Don't ask how I know this

Something tells me you've got a dirty chamber. Either the dirt was inside the chamber or on the cartridge when you chambered the round.

Indeed was a dirty chamber, look at that, i got squished powder in there.
So, next question, why in the heck i got all that powder in there not burnt???

Usually it happens from a pulled bullet. Matt

You're the only one who knows how it got there, it didn't burn because your necks are sealing the chamber like they are designed.

My experience was exactly what @dkhunt14 Matt described above.

Did you load a cartridge that didn't have a primer?

Dkhunt14, i never shot on this rifle no other bullets then the one's i reload, maybe something wrong with my reload??

Something may have been in the die and it wasn't noticed before firing..

Are you positive that the dents were not there prior to firing the round?
Lapua has had some issues with dents in the shoulder area on 6BR brass.
If you have some brass that has not been fire formed inspect the shoulders, you may find your answer.
It really does look like a trash mark.

my vote is you need to clean chamber and die.

what lube are you using?

the reason i ask is something similar happened to but.i caught it when it.came.out of the sizing die.

i use imperial sizing wax and imperial dry neck lube. i didn't notice but one of the ceramic balls in the neck lube stuck to the shoulder of the case and was crushed in the sizing die leaving a dent like that. i trashed the case and have been much more careful since.

 

[JackTheRipper]

Already sorted things out.

Two things, a dirty chamber and also the powder was too fast for this load.
