[QUOTE="Clark, post: 729780, member: 6600"] For strong rifles and traditional powders, I work up to the threshold of acceptable brass life and back off 6% powder charge ala Vernon Speer 1956. For extreme powders, I will do 4%. To find the threshold of loose primer pockets, I measure, with dial calipers, the extractor groove all the way around before and after firing. This is much more sensitive and repeatable than feeling how hard it is to insert the next primer. [/QUOTE]
