The Sport has the better handling and points so well. Looks sportier too. But the 45 is probably a better mousetrap. That weight forwardness is a boon to shooting in the field against wind. The trigger a whole lot better too. Darn good rifle, every bit as good as a HW80. Only thing letting it down is the stock isn't quite sexy enough; walnut and some cheek piece contouring set off with some checkering would do it.
Thats from a FWB Sports fan.
