I would like to pose a question to the experienced handloaders here. I have read in several books that flattened and cratered primers are a danger sign for pressure. But I am getting flattened and cratered primers with factory loads in my 460 Rowland. Here is a pic. The question is this. Is this really a sign of danger, or just the authors of reloading books playing it overly cautious?
