Federal Terminal Ascent BC's?

[Jumpalot]

I'm getting reading to start playing with the 155grn in my 7PRC. Just curious if anyone has experience on if the BC's are accurate. I think these bullets may be the cat's meow. Thanks in advance for any help.

They shoot lights out in my sons Bergara Wilderness 7 mm mags. One shot a bull at 660 and the other son at 600 yards.! Nice tiny groups!
