I bought several boxes of those hollow points once upon a year. I still use them. They've preformed quite nicely in all of my shooters. My box is white with the red super X logo. The end flap is marked with Winchester Super X, X30301, 150 grain hollow points. I'm sure that they are at least more than ten years old. There is no doubt in my mind that these were made with deer in mind. From your discription, I believe that yours are newer manufacture than mine. Use them on deer with confidence... I do!
