Hi there. I'm rather new to shotguns, so please forgive any ignorance. I recently purchased a Beretta A300 Outlander semi-auto for bird hunting (grouse/woodcock). A friend asked me to go deer hunting. Beretta does not make a slug barrel for this gun, but I'd like to use it for deer, if I can. Questions: Can slugs be shot through the smooth bore barrel? If so, do the slugs need to be rifled slugs? What choke should be used? thanks in advance!
