I've used a bunch of Nosler brass in recent years and found it to be very good stuff.
On the other hand, I've used a lot of Winchester, Federal and Remington brass over the decades without any problems.
My oldest 270 is on its second barrel and there are 3 other 270's in the collection. It's a caliber that sees a lot of use.

Imagine your grave on a windy winter night. You've been dead for 70 years.
It's been 50 since a visitor last paused at your tombstone.....
Now explain why you're in a pissy mood today.
