I'm calling B.S. on some of the data. They list a Ballistic Coefficient of .825 for a .338 dia. 266 Grain Spitzer Boat Tail. No way. Sierra's 300 Gr. .338 Matchking has a B.C. of only .768 above 2,300 FPS. It has a higher sectional density because it is heavier with the same bore dia. A 266 Grain .338 is going to be far less than that. Bill T.
