Brownells 75th Anniversary - A Shooting Heritage

Advanced Technology for Clean, Reliable Kills of Thin-Skinned Game

The Broadhead Dupo 28 shotgun slug from D Dupleks is a revolutionary advance in shotgun slug design. Unlike a traditional slug that is essentially a flying lump of lead, the Broadhead Dupo 28 was engineered from the ground up for excellent energy transfer and managed penetration on impact to take down thin-skinned North American game like deer, javelina, mountain lion, lynx, feral hogs, and that perennial baddie, Mr. Coyote.

D Dupleks’s aerodynamically self-stabilizing, hollowpoint slug body ensures deep penetration into vital organs, while six petals open to 266% of the slug’s original diameter to deliver superb expansion and a huge wound channel. Risk of over-penetration is minimal to non-existent, while even an imperfect hit can result in incapacitation of vital organs.

  • 95% weight retention - all the slug’s energy goes into a quick, clean kill
  • Non-toxic steel and polyethylene slug construction
  • Suitable for both smoothbore AND rifled barrels
  • Safe for all chokes
  • Polyethylene bearing surfaces reduce bore friction

Take D Dupleks Broadhead Dupo 28 ammo on your next hunt and see what a shotgun slug is truly capable of achieving!
