I have gone through lots of cartridge hunting over the years , I have always had a few different ones on hand ,and usually one for a sheep rig. I have finally gotten rid of every thing I owned from customs to factory rifles ,and went with a Cooper 280AI for my plains long range rifle ,and a semi custom Kimber Montana in a 280 AI for a sheep rig . I figured I would get the best of both worlds, and the 280 AI seems to fit the bill , it is close to a 7 Mag without the recoil thus no break required. With the 280 AI I would not hesitate to shoot anything out to 800yards in relative good conditions , you could load up some 168 Bergers for large stuff ,and 120-140 for the smaller game . Just my opinion thou, and the 280AI seems easy to load for, and is mild to shoot but has legs to get out there due to the large selection of high BC bullets. I am sure that there are many who will disagree as they like the big magnums but like I said I don't like loud breaks or recoil so I think I have found a great compromise .
