[QUOTE="Dean2, post: 541644, member: 26077"] The velocity is high, actually over book at that charge weight but they were using a 24" barrel and I am using a 27". Since velocity equals pressure and all that you would think they are running hot, but the primers are not at all flat or cratered, no ejector marks and the base of the cases mike within .001 of a fired factory case ther is no evidence of excess pressure. Also, the brass I am shooting these out of have 6 loadings on them, are only neck sized, still chamber very smooth and were trimmed once at the 4th loading, so brass life is fine so far. [/QUOTE]
