The 7x57 is one of my favorite cartridges. Period. The only other that might tie for first place with me is 6.5x55. The 7 is fun to load for, shoots sub-moa for me consistently and easily and has been a stone killer with all 1-shot kills. The farthest I've tracked a deer shot with it is 20 feet over a shoulder into a greenbrier patch. The blood trail was huge. It's easy to shoot and effective. A little more pop to it than the 6.5. I am hunting exclusively with Hornady 139's. Very adequate for my needs but I wouldn't hesitate to go to 150's or heavier bullets if I needed to for larger game.
