Jake, yes Sir. Just remove the Extra Full turkey Choke and use Foster Type Slugs for the best results. Recommendation here : midwayusa.com/product/1601572451?pid=589190

Jake, yes it can, but not with the extra full turkey choke. Improved cylinder usually gives best results for slugs. And make sure to use rifles slugs. Have a great day!

Yes, this could be used for deer with slugs but this only includes a extra full choke Wich is definitely not recommended for using slugs. You want a less constrictve choke like cylinder or improved cylinder. This has a win choke pattern, so as long as you buy a win choke in either cylinder or improved cylinder then this will work fine with rifled slugs for Deer. Hope this helps.
