[QUOTE="emp1953, post: 2047379, member: 71817"] It could make that difference for you. Winchesters will work fine. If you mix head stamps you are asking for frustration when it comes to accuracy. Try an experiment yourself. Take several mixed headstamp cases in the same caliber. Clean them, trim them, size them. Then weigh them all. The differences you will see in weight, since the cases are supposedly all the same, length etc, is in the case wall, web thickness etc. These weight differences make the inside volume of the case differ. That volume relates directly to pressure. Pressure is what pushes the bullet out the barrel. If the pressure is not very nearly the same every time your POI will change, frustrating the dickens out of you. I was able to score on several thousand FC demilled cases in my 4 favorite calibers. During a convalescence following surgery I sized and deprimed and trimmed them all, weighed them all. Found a few that differed way too much from the average for me to be comfortable with so I tossed them in the scrap bucket. Those cases would have exhibited a significant difference in velocity hence a different POI, had I used them. [/QUOTE]
