The Immortal: .30/06 Springfield The .30/06 is the Captain America of big-game cartridges. It’s been around forever, packs a punch, and helped us defeat the Nazis in World War II. Without question, it is the number-one big-game round of the 20th Century. And it’s still going strong. Like many other hunters, my first real deer rifle was chambered in the ought-six. Shooting 165-grain ballistic tips I put hundreds of pounds of corn-fed Michigan venison in the freezer over the years. I’ve also hunted with it across North America and in Africa, using 150-grain soft points, 180-grain Triple Shocks, 200-grain Trophy Bonded Bear Claws, 180-grain Accubonds, and a bunch of other bullets I can’t think of at the moment. You won’t find another round with a more versatile array of offerings. It really is the best all-around hunting rifle caliber. Physics plays a big part in the .30/06’s success. It strikes a good balance between power and shootability. The recoil generated by the ought-six is at the upper end of what most shooters can manage without developing a debilitating flinch. And its terminal ballistics can handle all but thick-skinned dangerous game. It’s certainly more gun than most whitetails require, but it gets the job done and carries with it a nostalgia that few cartridges can match. If it was good enough for Teddy Roosevelt, this deer hunting caliber is good enough for the likes of you and me.
