Hunting & suitability

Primary purpose

Suggested min muzzle energy
80 ft·lb

Game examples

Projectile alone does not establish ethical use; confirm legal species, rifle FPE, retained energy, accuracy, and shot placement. Hollowpoints are generally preferred where expansion and energy transfer matter.
