Hornady American Whitetail 7mm Rem Mag 139gr InterLock SP Ammo

The Hornady American Whitetail 7mm Remington Magnum ammunition delivers proven performance for hunters pursuing medium to large game across varied terrain. This 139-grain InterLock Spire Point load combines flat trajectory with controlled expansion to maximize effectiveness on whitetail deer and similar-sized game.

What Makes This Different

The InterLock ring mechanically locks the core and jacket together during expansion, preventing separation that causes other bullets to fragment. This design maintains 90-95% weight retention compared to standard cup-and-core bullets that often lose 30-40% of their mass. The spire point profile reduces drag for flatter trajectories at extended ranges while initiating reliable expansion on impact.

Key Features

• 139-grain InterLock Spire Point bullet with mechanical core-jacket lock
• 7mm Remington Magnum chambering for flat shooting performance
• Optimized powder charge for consistent velocities and accuracy
• Brass cases suitable for reloading with proper equipment
• 20 rounds per box, 200 rounds per case (10 boxes)
• Boxer-primed cases for easy decapping and reloading
• Quality control tested for consistent performance

Field testing demonstrates consistent 1.5-2 MOA accuracy from quality hunting rifles with proper scope mounting. The 139-grain weight provides optimal balance between velocity and energy retention for shots from 100-400 yards on deer-sized game. Weather-resistant primer and powder charges maintain reliability in temperature extremes from -20°F to 140°F storage conditions.
