Hence why the factory precision hunter 7mm08 holds 1000ftlbs to 700 yard while a 270 only holds it to 750 yards at the cost of significantly more recoil and 200fps higher muzzle velocity. At extended range BC is fairly significant for retaining energy . Obviously need a balance it with velocity to allow the projectile to expand and do it job. Should have a bloody good load there mate!

I'm certainly very pleased with the results
