Overview
Built for hunters loading .458 caliber rifles, this Barnes bullet is designed to combine a polymer tip with a boat-tail profile to support expansion and ballistic coefficient. Its all-copper construction and re-engineered nose cavity are presented as part of a design focused on rapid expansion, maximum weight retention, and deeper penetration than lead-core bullets. The multiple precision-cut rings on the shank are an added feature intended to support consistent performance. It is a practical choice for serious big-game applications where controlled terminal behavior matters.

Considerations & Trade-offs
- All-copper construction and a 300gr .458 caliber profile make this a specialized hunting bullet, so it is best matched to rifles and loads set up for that application.
- The polymer tip is designed to boost B.C. and start expansion, which means it is intended for hunting use rather than general-purpose target shooting.
- This bullet is described as offering rapid expansion and maximum weight retention, but those characteristics may not align with every hunter’s preference for terminal behavior.
- Packaged 50 per box, so it may be more of a dedicated hunting component than a high-volume practice option.
