† No ballistic coefficient is recorded for this projectile itself — some bullets are only ever published as part of a loaded round. This is Sellier & Bellot’s published G7 BC for the .303 British load (SB303B). 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.
