Performance Characteristics

The 550-grain hard cast bullet is engineered for deep penetration and consistent expansion. Subsonic velocity reduces noise signature and recoil impulse, making this load suitable for:

  • Suppressed rifle shooting
  • Hunting in noise-sensitive areas
  • Training and practice with reduced fatigue
  • Lever-action rifle shooting where lighter recoil is beneficial

Why Hard Cast Lead

Hard cast bullets resist deformation during firing and penetration, delivering straight-line performance through heavy cover. This construction is particularly valued in hunting applications where reliability matters.

HSM ammunition is manufactured to exacting standards, offering shooters a balance of performance and value across a wide range of calibers and applications.
