The Barnes Expander MZ Muzzleloader Bullets with Sabot are designed with a sectional density of 0.211 and ballistic coefficient of 0.207. These bullets are popular among seasoned hunters who look for confidence and one-shot kill ability in their ammunition.

The bullets offer improved velocities and enhanced accuracy over competing bullets. At both low and high velocities these bullets can deliver deadly force. In addition they are made to expand to twice the original diameter which ultimately creates copper petals that are razor sharp and able to cut through large game with no fragmentation.
