- This is a lead-free, 100% copper bullet, so it may not suit hunters who prefer traditional lead-core projectiles or need to match a specific load preference.

- At 500 grains, this is a specialized .458-caliber hunting bullet, so it is best suited to appropriate big-game applications rather than general-purpose shooting.
