Remington fully rifled barrels should only be used with Sabot Slugs. They are not intended for use with lead or steel shot. The rifling will deform the shot causing it to be inaccurate. Steel, Wingmaster HD or Hevi-Shot can potentially damage the rifling.
If you are looking for a "multi-purpose" barrel, we would suggest purchasing a smooth bore, Rem-Choke barrel. With this interchangeable choke barrel, you can use a fully rifled choke tube for Sabot Slugs, or an improved cylinder, modified, or full choke for lead or steel shot.
A listing of the Remington extra barrels is available through our online store at www.shopremingtoncountry.com.
