I just picked up a bag of 270 win brass made by Winchester. I have used lots of Winchester brass in the past with pretty good luck. But this bag I got has only what I want to say 19 pieces that I would trust to give me good accurate loads and consistent burn. It's all in the flash hole where I'm seeing the issue. It's ablong and has a chamfer or chip out of the edge of the hole. Click on the picture and zoom in and see what you guys think.
