Have been using Nosler 140 BalTip in my .280 Ruger 77 over H4831sc for years. It will shoot 1" groups all day at 100 yds. Deer don't have a chance. Just acquired a .280 Encore barrel. Haven't shot it yet, but hope the same load works. Nosler Accubond shoots exactly the same as the BalTip in my Ruger. :-D
