Don't get me wrong, I've followed up wounded brown bears with a Whitworth 30-06 and a Whitworth .375 Holland & Holland and even a 7mm Remington Magnum. But when in close range -- such as Kiliuda Bay, Spiridon, Afognqk Island, Raspberry, Martin River, Cape Yakutaga, Montague, among many other locations -- I definitely love the feel of a 20 inch 870 Remington with buckshot, then followed by alternating slugs. But, that's me, based on my experience, which is somewhat extensive.
