So far, the 'el cheapo' Federal bulk pack 50gr HP that is sold through Wally World for $58 per 200rds out scores Black Hills blue box by a little in my two 1/9 twist ARs.
I usually load up on it when I can find it, as the primers are crimped and if I lose it on the range or at a match, it's one step in the reloading process I don't have to worry about.
I tend to be a 'brass hound' for all the others... /ubbthreads/images/graemlins/tongue.gif
