If indeed they ever made one it would be a toughie to find. I haven't run across any and I look at the classified's all the time. I have had the 7 Rem mag , my brother owns one as well and absolutely loves it as does my best friend. YOu may want to look at a Bar in that Caliber. Factory ammo in a 280 is pretty disappointing and face it your looking at a handloading proposition. Also bear in mind you can't run HE ammo thru a Bar. Weightwise between the 2 there would be minimal difference and the recoil won't imagine to a hill of beans. You may want to call Browning to make sure they even made one. Good Luck in your search.
