[QUOTE="Sludge, post: 192944, member: 1928"] A couple of questions about primer consistancy... 1 - Has anyone studied variability of groups of primers as they affect the MV, ES and SD of chronograph results? If so, what primers indicated the greatest variability? Do the chronograph results also have a correlation to weight changes measured prior to firing of the primers? 2 - Has anyone ever studied the affect of different primers on the MV of identical loads shot from the same rifle? (to include different manufacturer and different lot number from the same manufacturer) In other words which primers were hot (fast) or cold? I know im probably getting caught up in minutia, but im curious about this none the less. [/QUOTE]
