The Weatherby Model 307 MZY 45 Cal Basic Peep 26" Brake is a modern muzzleloader built on Weatherby’s modular Model 307 platform to deliver centerfire-like performance in a front-loading design. At its core is the Arrowhead Gen2 Ignition System, using precision-fit primer modules and large rifle primers to provide hotter, more consistent ignition while fully sealing the breech to reduce blowback and protect the action.

This 45 caliber muzzleloader features a 26" barrel capped with an Accubrake DST muzzle brake for improved recoil control, paired with a basic peep sight system for clean, intuitive aiming. The rifle wears a graphite black Cerakote finish over the receiver, barrel, bolt, bolt knob, and brake, complemented by an exposed carbon fiber stock with black sponge pattern accents. Ideal for dedicated muzzleloader seasons and western hunts where modern inline performance is desired, the Model 307 MZY reflects Weatherby’s long-standing reputation for precision, innovation, and refined craftsmanship.
