Dimpled brass

[OG10]

I had the exact same thing happened in a .308 rifle it was a burr in the chamber causing the problem just a thought better safe than sorry.

Then it might be a primer issue???

If this were the case, wouldn't there be soot in/near the dimple?

The entire neck shows it....

The dimpling has happened about a half dozen times during this process.

This should have concerned you. It appears you have started your loading below safe minimum, this is as often just as dangerous as starting at maximum book loads.
Increase powder!

Cheers.

Anyone have an idea why this is happening. It shows no sign of excess pressure. I chrony every shot and this one was about 30 fps slower. This is a 6.5-06. The brass was made by sizing 270 brass down and trimming excess length.

Women really like Dimples!!!
