Hi Jack. 3 months ago I was trying to figure out how the average person is supposed to deal with Sierra’s published BC specs. The BC changes with the velocity. I also looked at the Hornady program. This is all described in a post entitled “Hornady ‘4DOFF’” under the “Precision long range hunting and shooting” section. I agree with your theory that a 150 grain bullet out of a 30-06 a deadly combination, due to the MV that is possible. However, I’m convinced that a heavier bullet, at a slightly slower velocity, provides an advantage at long range. This is based on one bad experience I had with a 150 grain projectile.
