I bought 500 rounds of this ammo when I first built my creedmore rifle. After getting the barrel broken in and getting it sighted in, I find that the gun and ammo combination will shoot 5/8 moa or so. I would like to dial it in to shoot the rest of the ammo at ranges longer than 400 yards and would like to build a profile on my kestrel to dial the shots in on the first shot. Does anyone know what the BC of these bullets used by Federal are? I have not been able to find it on any of the packaging for these rounds. Thanks in advance!
