Winchester will replace the bag, if you send it in. I have heard they have done better in the last couple of years with warranty replacements, but I had a bag of 243win brass from them a few years ago which had bad flash hole punches in over half of the brass, I had to send them in with a paper form and a check for return shipping. You might imagine what my response to Winchester was when they told me such...

Largely, I don’t and won’t buy Winchester brass any longer for that reason. Way too many quality control issues for them, and they use an archaic means to manage customer service and warranty replacement issues - there are prettier girls to dance with.
