Here in NS the largest shot we can use is AAA buckskot . .slugs in deer and bear hunting or I can use the slug to dispatch bears in my snare . I use BB instead of buckshot . Close range shooting with the bear in a snare .I don't have a rifled barrel for slugs . I definately won't skoot slugs from my gun with the choked barrel . I have the screw in chokes . I met a gut in Canadian Tire one time in the sporting section with a choke in his hand with the side out of it . I asked what happened to it and he said he was shooting slugs . Not the plan !!!!!!
