The Winchester Copper Impact 20 gauge sabot slug answers the call for hunters operating in lead-free zones without compromising lethality. Chambered in 20 gauge and launching a 3/4-ounce solid copper projectile at 1600 feet per second, this load bridges regulatory compliance with field-proven terminal ballistics. The large-diameter red polymer tip initiates expansion on impact, while the monolithic copper construction retains weight through bone and tissue—qualities that matter when a whitetail buck steps into the clearing at 75 yards and you’re hunting public land with lead restrictions.
Built for the Box
Winchester engineered the Copper Impact series around a solid copper hollow-point design reinforced by a red polymer tip. The tip serves dual purposes: it accelerates bullet expansion upon striking soft tissue, and it visually distinguishes this lead-free load from standard Deer Season XP rounds in your vest. Each 2-3/4″ shell generates 1847 foot-pounds of muzzle energy, sufficient for ethical one-shot kills on deer-sized game at typical shotgun hunting ranges. Boxer-primed hulls with roll crimps deliver consistent ignition and allow reloading for shooters who process their own brass.

This sabot slug requires rifled-bore shotgun barrels for optimal accuracy. Smoothbore barrels will destabilize the projectile and degrade downrange performance. For hunters pursuing deer in states or counties mandating non-toxic ammunition, the Copper Impact load offers a compliant option without switching to centerfire rifles.
