Varmint hunting places extreme demands on bullet performance. Such bullets must be exceptionally accurate to hit small targets, lightly constructed to provide explosive expansion while minimizing ricochets, and lightweight to obtain high velocities with flat trajectories. Sierra Varminter bullets are the standard against which other brands are measured. .22 Caliber Hornet Varminter 40 Grain Diameter: .223/5.66mm Sectional Density: .115 Ballistic Coefficients: .117 @ 2800 fps and above; .123 between 2800 and 2000; .136 @ 2000 fps and below Note: These are component bullets, not loaded ammunition.
