[QUOTE="MagnumManiac, post: 982583, member: 10755"] Yes, all brands of primers differ in hardness and heat. Federal are normally softer than other brands, but not always, Winchester magnum primers are hotter than Federal magnum primers, etc, etc. CCI are probably the hardest of all primer brands. Primer cratering, unless other excessive pressure signs are present, are normally caused by a gun condition, not a load condition. Recently manufactured rifles by Remington and Winchester have a small bevel machined into the firing pin hole, why I don't know (I did ask), this is the cause of cratering in these rifles, not the size of the hole itself. As far as your loading goes, if you have loaded to the book max and seen no indications of excessive pressure, then only you and your experience should tell you if it's safe to do so, not ANYONE ELSE, if you need to ask, then maybe you should not go past book max. There are a few things you need to know, which would take more space than is available here. Cheers. gun) [/QUOTE]
