I made another unsuccessful attempt at contacting Accurate Arms via their Web page today so it looks as though I will have to use snail mail to ask my question.
It does seem strange though that the quoted min and max loads with AA 2520 for the 174 gr HPBT bullet (35.1-39.0 42,500 CUP) are so low when compared with those for the 150gr SP bullet (41.4-46.0 45,000 CUP) and the 180gr SP bullet (39.6-44.0 45,000 CUP)
