CCI In-Line Muzzleloader Primers (brand part no. 0307) are purpose-built for in-line muzzleloader ignition systems, giving black powder and muzzleloader shooters a primer formulated to work reliably even in humid field conditions. This muzzleloader-specific formulation is more sensitive and easier to seat than standard primers, while also being compatible with progressive and automated loading equipment. The formula is engineered to reduce fouling, which helps keep your muzzleloader’s ignition system running cleanly between shots. Each box holds 100 primers, enough for a full season of range and field use.
