Remington Ultimate Muzzleoader U.M.L Ignition source

BOLT-ACTION CENTERFIRE SIMPLICITY

Engineered exclusively for the Ultimate Muzzleloader, pre-primed cases load with the ease of any centerfire. And super-hot magnum primers ignite up to 200-grain loads with near smokeless efficiency. The flash channel stays clean and ready for the next load and there's no need to remove the breech plug for cleanup.
