yes it can shoot "rifled" slugs it can also shoot sabot slugs but they are not accurate out of a smooth bore barrel try the slugs in both mod and IC to see which is the most accurate with that slug

Hi Donald and welcome. Yes it is. Foster type slugs will favor Improved Cylinder or Modified Chokes depending on the individual firearm. Just take a few minutes and see which choke your shotgun gives the best accuracy with at a modest distance. Full Chokes tend to have too much restriction and deforms the slug when it exits and ruins accuracy. Cheers and stay safe!

For sure it absolutely does!! Rifled slugs will get you the accuracy you want out of a smooth bore shotgun.

Hi Donald, yes sir, this will fire slugs. For best results use rifled slugs with the improved cylinder choke that comes with the shotgun. Do not fire slugs through a full choke.
Stay safe & have a great day!
