I'm reloading 6.5 Creedmoor for the first time. I have some Sellier & Bellot and Herter's loaded Winchester brass. It was factory ammo and only fired once.

This Winchester case already has a split in the neck. I only washed it in an ultrasonic bath, not resizing yet at all.

Does anyone see this often out of Winchester brass?

I think this needs to be the virgin lower on which a cheese themed AOW is built. What are y'all's thoughts?
