My name's Mark, this is my first post. I hope it's in the correct forum. I've been shooting the Walmart winchester white box value pack 100rnd 9mm stuff for awhile. I've never had any issues until today. Is it NEW ammo or factory reloaded? I ask because the headstamp is different than normal (I police my brass to reload it)AND I found an empty case in the box with cleaning media stuck inside. It had a fresh primer just no bullet or powder. I just thought is was odd that it's gone from WIN9mm headstamp to a WCC nato cross headstamp, and with the empty case to me was a reload since it had cleaning media in it, and their quality has seemed to decline alot lately. Any thoughts?
