a remington 870, ithaca deerslayer, mossberg 500 or 835 slug guns, winchester 1300. they are all great slug guns but the mossberg and the deerslayer versions are more designed towards slug hunting, and ithaca's barrels are also perm. screwed into the reciever like rifles makeing them more stable and my personal choice, there are semi autos out there to but you have to check your state and local hunting regs first to make sure thier legal. i don't have any expierience with semi auto slug guns because they're not legal for big game hunting here in pennsylvania, so i can't answer about them.
