I've been looking at shotguns for a little while and my main priorities are something I can take to the skeet range, bird hunting, and a bear defense gun. I was talking to my husband last night about this and he said that you can't shoot slugs out of regular shotguns, that it could damage the barrel. I've never heard of this - and I went bear hunting with a friend who's the daughter of an NRA rep and she gave me her rem 11-87 with slugs, the same gun she's let me borrow at the skeet range as well. Is there any truth to this? Thanks!
