Best Suited For

  • Medium to large game hunting (e.g. deer, pigs, similar-sized animals)
  • Hunters using .270 Winchester, .270 WSM, or .270 Weatherby Magnum rifles
  • Reloaders seeking a balance of accuracy and controlled expansion
  • Longer-range hunting where improved ballistic efficiency is beneficial

The 150gr weight provides deeper penetration compared to lighter .270 projectiles, making it ideal for tougher game.

When To Use It

  • When hunting at moderate to extended ranges
  • When you need reliable expansion with retained weight
  • For load development in rifles that perform best with heavier .270 bullets (150gr class)
  • In windy conditions where higher ballistic coefficient helps maintain trajectory
