You know,those speeds that you got from Sierra are most likely for "optimal" expansion. IMO if he stated 3000 top end,if it impacted at 3050 or 3075 . . . no discernable difference.
Doing expieraments with bullets at 300BLK vels,the manufacturers like to use the words like . . . "optimal expansion" . . .
