That's typical of the trash Winchester is currently passing off as component brass, along with badly cleft shoulders, split necks, over-sized primer pockets, and so on. One would almost think the component brass is the culled brass from the factory ammo production line. I recently has 36 discards out of 100 .300 Winchester brass, mostly badly cleft shoulders, then after mailing the brass with the original bags, and the bills of sale to the Canadian agent for Winchester, Graywood Sporting Group, I never received a cheque or a replacement bag of brass as I requested. Lesson learned. Lapua, Norma, Nosler, and Previ from now on. The only way to get quality Winchester brass seems to be by purchasing Winchester factory ammo. Even at that, you then you have to contend with the miserable crimp they use, and trimming below it leaves a pretty short neck if you're loading .300 Winchester, or worse, .300 Savage.
