† No ballistic coefficient is recorded for this projectile itself — some bullets are only ever published as part of a loaded round. Across the 4 loads using this bullet, Sako quotes G1 BCs from 0.181 to 0.189; the highest is shown. A ballistic coefficient is a curve fit that drifts with velocity, so it will differ in another cartridge. Where a load below publishes its own figure, that is the one the comparison and solver use.
