Overview
Built for lever-gun hunters, this 250-grain .458 bullet is designed for use in 45-70 Govt. applications where controlled expansion and dependable performance matter. The copper-alloy construction is intended to provide a solid that won’t separate, while the Flex Tip design is described as helping initiate expansion at lower velocities common in mid- to long-range lever-gun shooting. It is offered as a 50-count box and is positioned for hunters who want a reloading component suited to traditional lever-action setups. Load data should be verified through a reloading manual or the powder manufacturer’s website.
