I have been reloading for a few months now and am learning a lot. One subject I do not feel that I comprehend very well is over pressure signs. I hear a lot of talk about it in reloading manuals and in forums but I have never been able to find detailed instructions -with pictures- to describe what to look for. I hear cratered primers, flatend primers, punctured primers, stretched bases. I kind of understand these things but I think some pictures with descriptions would help me ease my concern. If anyone has time to post something up or knows of a thread that addresses this please let me know.
Thanks
