I know this ammo is no longer manufactured but I have a good stash of Federal Premium 200 grain TBBC for my 300-win mag. I wanted to order a custom turret for my Leupold scope that is on the rifle. I know one of the pieces of info they need is the BC of the bullet. This info is not on the box, and I have not been able to find it with an internet search and a call to Federal. Does anybody know the Ballistic Coefficient of a 200 grain .308 caliber bullet? Any help would be appreciated. Thanks
