That could very well be the case with everyone else's core lokt problems, I havent bought any core lokts in about 9 years. Last time I bought core lokts I bought two 200 round cases I still have 5 boxes left from a case. I havent had the need to buy anymore since I started reloading even if i wasnt reloading those 5 boxes would probably last me another year or two. perhaps they have been real consistant for me for the simple fact that both cases were from the same lot. I think I may just go buy a new box from walmart tomorrow just to see how much different they are from what I have now. cross your fingers I will post tomorrow with the results.
