Something to consider. A 270WSM with a bullet like the Barnes 130gr TSX will shoot completely thru a mature elk . Even at very acute angles. Easily driven to 3300FPS with a slow powder it delivers less recoil than a 140 C&C plus a flatter trajectory. Also with the Barnes 270 110gr TTSX is a bullet capable of completely penetrating the largest muley buck. Even thru heavy bone. These bullets have to be tried to be appreciated & their capability understood. They far out penetrate the Nosler partition. Try one & see for your self.
