I just picked up an FN Police with an 18" barrel. It came with an IC and a Modified choke. I will be using this gun for HD and informal clay pigeon "plinking". I may eventually press it into service for deer hunting and/or pheasant. Should I consider a rifled choke tube with sabot slugs for deer? What's a good choke for what? What loads go well with what chokes? My last shotgun was a Maverick that only came with one choke, so I don't even know what it was because I never removed it.
