Overview

Built for hunters who want a slug load centered on accuracy, penetration, and high weight retention, this Hornady offering is designed for use where dependable terminal performance matters. Hornady’s Superperformance propellants are intended to drive flatter trajectories and support enhanced downrange performance, while the MonoFlex projectile uses a solid gilding metal construction with the Hornady Flex Tip to promote uniform expansion. The projectile is also described as retaining 95% of its original weight and not separating, making it a practical choice for hunters looking for a controlled-expansion slug load in a 5-round package.

Pros

  • Engineered for accuracy, penetration, and high weight retention in shotgun slug use.
  • Superperformance propellants are designed to deliver max velocity for flatter trajectories.
  • MonoFlex solid projectile is topped with Hornady's exclusive Flex Tip for uniform expansion.
  • Monolithic projectile construction helps the slug stay intact and retain 95% of its original weight.
  • Pack includes 5 rounds of 12 gauge 2 3/4 inch slugs.

Considerations & Trade-offs

  • Pack size is limited to 5 rounds, so it suits sight-in, testing, or a short hunt rather than extended range sessions.
  • The load is built around max velocity and flatter trajectory, which can make it more specialized than a general-purpose shotgun slug option.
  • The MonoFlex projectile is described as a solid, monolithic design with a Flex Tip, so it is intended for controlled expansion rather than a broad range of bullet styles.
  • This is a 2 3/4" 12 gauge slug load, so compatibility depends on a shotgun chambered for that specific shell length and gauge.
