Problem with 22/250 Brass Cracking

[EDG]

Kevin,
You might contact Winchester and ask them to replace the brass. They should replace it without a problem.
They might ask you to send them samples of the cracked cases so they can analyze the failures.
Asking manufacturers to do this helps them improve their processes.

Hornady has a history of soft brass (opposite of the OP's post but in line with the conversation). I've bought 6.5 Creedmoor and 6.5 Arisaka brass from them to only see multiple crushed shoulders upon initial bullet seating with my Hornady (6.5Cr) and LEE dies (6.5A). I also have sworn them off when they suggested my dies were not setup properly. I told them, that's funny, I don't have a problem when I resize308 Win (6.5Cr) and 35 Rem (6.5A) cases from other companies (Win,R-P)in the same dies...

Caveat Emptor with some company's claims of competence.

As much as this may surprise you, making a brass case is much more art than science.
I know that one of the biggest ammo makers in the world is actively working on trying
to make their processes for making brass cases a lot more science and a lot less
art than they are. They ship billions of rounds each year, but still sometimes the
magic escapes and there is a bad batch.

In modern engineering terminology, the process is not 'in control'. This means a lot
of money spent doing research, computer simulations and testing to see how to
best make the brass with the correct hardness in the head, elasticity and flexibility
in the middle and freedom from cracking and proper grip of the bullet in the neck.
A lot has been spent and more will be spent to make it more consistent.

Not simple.

This happened 2 years ago, he did say Winchester replaced them.

Years ago Winchester brass was never annealed properly, it was brittle, most people I knew
loaded Rems because of that fact. I used wins when I wanted a bit more volume but that
facilitated me into learning about and annealing the win brass. All my 30-06 AI is win brass
but properly annealed.
