I have recently bought some of this ammo. It groups tighter using my Blaser R8 than Federal at 100 yds but appears to have a greater drop than federal at 200yds plus. I use a Swarovski scope with ballistic turret but their software does not list this round. I have tried getting ballistic info from the UK agent but with no success, I have approached Sako only to be given the ballistic coefficient. A follow up request for more info has not been replied to after 7 weeks! Has anyone got any relevant ballistics for this round so I can set up the Swarovski table. It's the muzzle velocity I need.
