Went to the range yesterday, I used new Winchester cases, full length small base sized and loaded with either 50hr Vmax bullets or Varmint Grenades. NO split necks, I have the brass separated and will count the reloads. Think I may have had some issues with brittle brass. The 7-08 was all once fired R-P brass. Going to try Winchester brass next. I have had great luck with Winchester nickel plated brass in my 280 target rifle.
