The Nosler Model 21 bolt-action rifle in .300 Win Mag combines precision engineering with field-ready reliability—built to perform across demanding hunts without compromise. This is a production rifle with custom-gun credentials, designed collaboratively with Mack Brothers (the South Dakota innovators behind the respected EVO action) and refined with Nosler's own performance specifications. The result is a firearm that feels and shoots like a bench-built custom, but arrives ready to hunt at roughly 7.1 pounds.

Construction centers on a wire EDM machined receiver paired with a fluted bolt finished in nitride coating for durability and corrosion resistance. The barrel is Shilen match-grade stainless steel—the kind of component you'd specify for a rifle built to last a decade or more. Control duties go to a TriggerTech trigger, known for clean breaks and reliability. The McMillan carbon fiber stock adds rigidity while keeping weight minimal, and the overall package measures 44.5 inches with a 13.5-inch length of pull, balancing shootability for varied frames.

Chambered in .300 Win Mag with a 1:10 twist and #3 barrel contour, the Model 21 handles the heavy hitters. Magazine capacity sits at 3 rounds, typical for long-action magnum hunting. Whether you're glassing ridge country for elk or setting up for longer-range deer, this rifle delivers the precision accuracy hunters expect from a Nosler while remaining packable and reliable enough to trust on any season, any terrain.
