Considerations & Trade-offs

  • Sold in a 5-round box, so it’s a limited-quantity option and may require multiple boxes for extended range time or a full season’s supply.
  • This is a 12 gauge 2.75" rifled slug load, so it’s intended for compatible slug setups rather than general-purpose shotgun use.
  • The hollow point design is geared toward hunting use, which may not be the right fit if you’re looking for a non-expanding target load.
  • At 1600 fps muzzle velocity, it’s a high-performance slug load that may produce more recoil than lighter target ammunition.
