I've got a Stevens 5100 sxs 12 ga, 24 in. barrels that I use for CAS. It's the only shotgun I own, and buying another is not an option right now. I have an opportunity to go duck hunting with a friend - can I shoot steel shot in it w/o doing damage to the gun? I've heard warnings about older shotguns, esp. sxs, not to use steel shot in them. Advice?
