My 280 mountain is one of my favorite rifles, shoots Nosler 140gr BTs better than I can, I kill my nicest buck with it on its maiden hunt. Only thing I've done to mine was install a triggertech primary. its wore a 3-9 stryka, 3-15 vortex razor, and now it has a 2-10 razor. It will be one of the last guns to go down the road.
