I am trying to work up a load using one of these bullets. They will be used for medium range (100-700) target and steel shooting. The rifle is a SAM-Rish setup with a WOA SDM barrel. The Hornady 75gr BTHP and Sierra 77gr MK have very similar BC's when tested. Hornady's published BC is a little high and actually falls right in with the 77SMK. The 75gr BTHP is cheaper and can be pushed a little faster. However, for some reason the 77SMK seems to be a more popular choice. What does it offer over the 75gr BTHP?
Thanks.
