I'll vote 6.5x47. I have two of them and they're a great cartridge. One is a heavier RBros build. Shoots 130 Berger's at 3000 FPS. Other is a lighter tree stand/carry rifle. It shoots the 124 HH at 2938 FPS. Both bullets have performed exceptionally well on deer out to the 500 yd mark. Lapua brass, CCI 450's, H4350.
