Weatherby's Model 307 MZY brings a rifleman's build quality to the muzzleloader world. It starts with the bolt action Model 307 platform and pairs it with a 26 inch barrel wearing a muzzle brake, so recoil from heavy 45 caliber charges comes back manageable instead of punishing. A peep sight sits on top, giving a clean, fast sight picture that works better in low dawn light than a notch and blade, and the receiver leaves you room to move to glass when you want it. The stock wears a black carbon finish that sheds weather without needing to be babied. At the heart of the MZY is the Arrowhead Gen2 Ignition System, a sealed design running precision fit primer modules with large rifle primers.For hunters chasing dedicated muzzleloader seasons, the 45 caliber bore has become the flat shooting choice, carrying better downrange than traditional 50 caliber setups. Few production muzzleloaders come braked at all, which makes the brake here a genuine advantage when you are pushing magnum charges. This is a muzzleloader for people who already own good rifles and expect the same feel when primitive season opens.
