[QUOTE="FearNoWind, post: 1209249, member: 50867"] I am baffled with this "hotter load" obsession that seems to becoming more popular all the time. Somehow the masses are beginning to believe the myth that "hotter is better" - it is not. Any increase in velocity achieved by pushing pressures to extremes (which seems to be the goal) is so slight it isn't worth the trouble. Find the load that correspond with the node and you've got everything you need. The [B]"Tea Leaf Reading" analogy[/B] is a pretty darn good description. Cratered or pierced primers may or may not indicate overload. How "flat" does a primer have to be to indicate overload? Are all cases made of the same grade of copper - if not which might be softer/harder than the next and are the ejector marks on one a greater or lesser indicator of overload. Is a case that's hard to extract a sign of overload or just a dirty chamber, anomaly in case structure or some other factor? End of rant ............. :D [/QUOTE]
