† No ballistic coefficient is recorded for this projectile itself — some bullets are only ever published as part of a loaded round. This is Sig Sauer’s published G1 BC for the .223 Remington load (E223M1), the same figure they quote across all 2 loads using this bullet. 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.
Shooters' reviews
Each review is one shooter's own experience. Reviews never change the figures, charts or comparisons on this page, which come from the manufacturer's published data.
