Matthew, yes sir, this will shoot slugs. Being a smoothbore barrel, you want to shoot rifled (or Foster) slugs. Have a great day!

Yes, Rifled slugs.

Matthew, yes Sir. The smooth bore with cylinder choke will perform best wit Foster Type Slugs : budsgunshop.com/product_info.php/products_id/411559534/rio+royal+star+slug+12+ga+2-34+1oz+slug+5rds

Matthew, yes sir. This has a smooth bore Barrel with a fixed cylinder choke so this will work with 2-3/4 inch or 3 inch bird shot, buck shot or slugs. Since this has a smooth bore rifled slugs will get the best accuracy. Hope this helps
