Agree with Brian, also, Sierra has a neat android app (ReloadingManual.Android) that has a slider for FPS
then the powder types and powder loads change based on that FPS slider.
I use it as a quick sanity check. (told me I'm not!)
ps: their Sierra 142 HPBT, 2.810", 41.6gn IMR4350 => 2650 FPS, a medium load..
