Just bought a NIB Ruger MKII in .280 Remington. I plan to put a VX-3 4.5x14x40 CDS scope on it. I do not reload. Before I order a dial I know I should be sure that the gun likes the ammo. However, before I begin I thought I would ask about experience ya'll have had with Factory Ammo. I will use the gun and ammo for South Texas Deer and possibly a Antelope Hunt someday. My ranges will run from 100-300 yards. I shoot a .300 Win Mag for Mule Deer and Elk. Federal Trophy Bonded Tip? Federal Barnes TSX? Federal Nosler Ballistic Tip? Hornday SST? Thanks for your input!!!
