The Model 307 MZY is Weatherby’s first ever muzzleloader built for hunters who want centerfire performance in a front end loader. Designed around the modular Model 307 platform the MZY brings a new standard of precision to the world of modern muzzleloading. At the heart of the MZY is the Arrowhead Gen2 Ignition System. Typically only found in the custom gun world this sealed rifle primer design solves the problem of other ignition systems. By using precision fit primer modules with large rifle primers the system delivers hotter and more consistent ignition through a short straight flame path while fully sealing the breech. This eliminates blowback protects the action and maintains repeatable headspace shot after shot. Available in both 45 and 50 cal options the MZY has options that are compliant in many western states. – FINISH – Receiver / Barrel / Bolt / Bolt Knob / Accubrake DST- Graphite Black Cerakote – Stock- Exposed carbon fiber with black sponge pattern accents
