Big crack in Lapua brass, a trend?

[OREGUN]

Virgin Lapua .284 Win brass fired in a .284 Shehane chamber. After my nine hour cleaning and polishing routine, I found this.

Several hundred cases from this same lot have been fired with no drama. I’m not suggesting anything, just thought it was interesting.

That piece of brass decided it wanted to be Harry Potter

Probably because they flame anneal.

Big ass crack......

Gawd, it just keeps going!

The brass has lost 60% of its thickness due to 9 hours of cleaning per round

Ok, so I had another one of these today. First firing on the brass. Same crack.
