† No ballistic coefficient is recorded for this projectile itself — some bullets are only ever published as part of a loaded round. This is Remington’s published G1 BC for the .270 Winchester load (28955). 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.
