I'm just starting out in long range shooting, but I know enough that the listed 0.53 G1 BC isn't enough for the Hornady 178 BTHP. Or even realistic. I have a site that I will be able to get a 1100 yard shot soon, and I would like to make a first round hit if possible with the Hornady Superformance ammo. I am doing my own spotting, and it might be hard to see where I am landing. Has anyone characterized the Hornady 178 BTHP for either a stepped G1 BC or preferably G7? Also, would any other loaded factory ammo be better for this (308 Winchester)? I am not reloading yet. Thanks.
