Federal lists this projectile as having a BC of 0.414. For a 150gr soft point .308...that is...impressive...
Has anyone actually verified that this is actual and not inflated? If so, details?

Here is a picture of the projectile in question. The Meplat is 0.10", the AOL is 1.058", the length of the nose until it hits bearing-surface just forward the cannelure is: 0.630", and the length of the boat-tail section is 0.1", with the base diameter of 0.24"
As you can see, it appears to be a very slight secant ogive design, with a "two stage" boat-tail or something, I dunno what I'd call it. Anyway, thoughts on actual G1 BC? Friend of mine said it might actually be 0.4's.
Just my 2 cents... but the G1 for a Sierra 150gr FMJ is .408 @2800 fps and above.
And their 150gr soft point , flat base has a .336 above 2600fps...
So, imho, that seems kind of optimistic to me.
I spoke with leupold and we kind of agreed 0.380 would get me close enough that environmental would matter more.
Comparing to a 155 Lapua Scenar, which has a G1 BC of .460, I would have to think that .414 may not be too far off. They are leaving the muzzle at 2800 FPS (24" barrel) which helps you shoot a little flatter and may be the magic number for that bullet.
When I hear the words long range, I think 1000 yards. Shooting for 1000 yards, that bullet may not be real consistent when going transonic. The next concern would be how consistent that bullet is compared to a match grade bullet. In my accuracy testing of the 223 Load with the 75 GD, the accuracy was impressive so you may be good in that department.
-Seconds Count. Misses Don't-
Data I'm getting back suggests 0.332 G1, so far. Margin of error around 0.01.
