[QUOTE="Coyboy, post: 729952, member: 3733"] The quick and dirty answer is yes, you can see a slight velocity decrease with newly annealed brass, from it's pre-annealed state. I have seen it with my f-class loads often enough that I normally bump up the powder charge .2-.3 grains on the first loading after annealing. I guess you could say I seen it enough that before the PRS finally which was Dec 1 and 2nd, I annealed all my 6xc brass ( about 400 pcs). Then I loaded it for the biggest match of the year with an extra .2 grains with-out ever testing it. My velocity was within 3 fps of the brass pre-annealing. This allowed me to use all my currrent accumulated data, saving me a bunch of test time. [/QUOTE]
