I Built the World’s Most Accurate 7 Backcountry Rifle

The 7mm Backcountry, rolled out by Federal earlier this year, has generated more interest and controversy than any other cartridge introduction in years. It sets a new performance standard by using steel alloy cases — called Peak Alloy by Federal — capable of containing higher pressures than traditional brass. And it's mostly been chambered in light hunting rifles.

But I wondered about the accuracy potential of the 7 BC and what it would look like if it was put through a rifle designed for long-range precision. So, I set out to build a heavy-barreled rifle and make the world’s most accurate 7 Backcountry to date. Here's what the rifle is and how it shot.
