I have a 6.5X56 Mannlicher and I use the PPU 156 grain RN bullets in it. So far they have been excellent and priced right. I shot Sierra 160 grain and also Hornady 160 grain bullets in my rifle and killed game with both. The PPU bullets seem better then either the Hornady or the Sierra in staying together inside the bodies without break ups Also are every bit as accurate and possible a bit more accurate then either of the American bullets.
