Power, reach, and proven terminal performance—everything big-game hunters expect from the .300 Win Mag. The Ammo Inc HUNTSP .300 Winchester Magnum 180gr InterLock® SP pairs quality brass and consistent propellant with Hornady’s time-tested InterLock® Soft Point, delivering controlled expansion, deep penetration, and hunt-ready accuracy. This 10-box case (200 rounds) gives you the volume to zero, practice, and head into the season with confidence using the exact load you’ll carry in the field.

Why Hunters Choose This Load

  • InterLock® Reliability: A tapered jacket and mechanical InterLock ring keep the lead core and jacket together for excellent weight retention and straight-line penetration through bone and dense tissue.

  • Ideal 180gr Weight: The classic 180-grain .300 Win Mag recipe offers a smart balance of flat trajectory, wind resistance, and on-impact energy—perfect for elk, mule deer, whitetail, hogs, and similar big game.

  • Consistent Accuracy: Ammo Inc’s clean-burning powder, quality primers, and concentric brass support tight groups and repeatable point of impact across varying conditions.

  • Bulk Value (200 Rounds): Ten 20-round boxes let you train with what you hunt, minimizing POI surprises while validating drops and wind holds.

  • Reloadable Brass: Boxer-primed brass cases add value for handloaders.

InterLock® SP: What It Means in the Field

  • Controlled Expansion: The soft-point tip initiates rapid yet controlled upset for a broad, effective wound channel.

  • Mechanical Lock: The InterLock ring and cannelure help prevent jacket-core separation, promoting deep penetration on quartering or broadside shots.

  • Proven Track Record: Decades of success on North American big game when paired with sound shot placement.

Ideal Game & Environments

  • Elk & Moose (within ethical ranges): Heavy 180gr mass with strong jacket construction for big-boned animals.

  • Mule Deer & Whitetail: Flat flight and decisive energy transfer across timber, cuts, and open basins.

  • Hogs & Exotics: Reliable terminal performance on tough animals with varied angles.

  • Western & Mountain Hunts: Excellent for cross-canyon winds and longer shot opportunities (verify your dope and personal limits).

Range-to-Field Advantages

  • Train With the Exact Load: The 200-round case lets you confirm cold-bore POI, practice positional shooting, and validate real ballistic data without changing ammo.

  • Confidence at Distance: Consistency across lots reduces variables so you can focus on wind calls and clean trigger presses.
