Speer GD & FPE?
Based off of some suggestions here, I'm using 250gr .45 speer gold dot / deep curl bullets with harvester CR sabots and 90gr BH209. I have a ballistics calculator on my phone that I was messing around with and the way I have it sighted in (2.75" high at 75) and estimated 1820fps shows me a +/1 5" hit out to 174 yards. After that's all said - is there a way to estimate how much fps / fpe is needed to get the bullet to perform properly (expand and exit the other side of the vehicle or just stop short of that)?
