Weatherby H300180IL Select 300 Wby Mag 180gr Hornady Interlock

The Weatherby H300180IL Select ammunition delivers magnum performance with premium Hornady Interlock bullets designed for controlled expansion and deep penetration. This 300 Weatherby Magnum load combines Weatherby's precision manufacturing with proven Hornady projectile technology for consistent accuracy at extended ranges.

What Makes This Different

The Hornady Interlock bullet features a raised ring that mechanically locks the core and jacket together, preventing separation during expansion. This design maintains 90-95% weight retention compared to standard soft-point bullets that often lose 30-40% of their mass. The 300 Weatherby Magnum cartridge generates 3,240 fps muzzle velocity with 180-grain bullets, delivering 25% more energy than comparable 30-06 loads at 300 yards.
