CartridgeKits - .50 Caliber Cartridge Former Deluxe Kit - Essential Tools Included - CK-50DELUXE

The CartridgeKits Master .50 Caliber Cartridge Former Kit redefines how you think about reloading in the field. In a real hunting scenario, the need for a second shot usually comes in a high-adrenaline moment—whether you're following up on a successful hit or reacting quickly after a missed opportunity. This kit is built to make that crucial reload faster, smoother, and more reliable when every second counts.

The .50 Caliber Paper Cartridge Forming Kit has everything you need to start making reliable, ready-to-use paper cartridges for your .50 caliber muzzleloader—just add your favorite bullets and powder. It includes a precision-machined knob and block set made specifically for .50 cal, a marked powder measure for consistent loads, and a funnel to keep things clean and simple. You’ll also get two packs of rice paper rolling papers for strong, clean-burning cartridges, a 5/8" paper circle cutter for perfect base cuts, and a standard-size glue stick to hold everything together. To keep things organized, the kit comes with a loading block, a sliding cap wallet, and a convenient carrying case. Whether you’re getting ready for hunting season or just want a smoother range day, this kit makes building your own paper cartridges easy and efficient.

Creating a paper cartridge solution for the popular .50 caliber inline muzzleloader brought unique challenges—and innovations. To ensure fast, seamless loading, CartridgeKits engineered a dramatically sloped cartridge body, resulting in a long, slim design that drops easily into the barrel with no resistance. While slightly more involved to form than our other kits, the performance in the field makes the extra effort well worth it.

Most modern inline shooters use saboted slugs, which are already a snug fit in the bore. Adding a paper wrap tightens that fit slightly, so it's important to sight in using the same paper cartridges you plan to hunt with. They load without difficulty, but consistency matters when it’s time to make the shot.

For those casting their own bullets or moving away from sabots, this kit works seamlessly with lead conicals and roundballs. No wad is needed—paper sides provide effective gas sealing. If you notice black streaks (a sign of gas cutting), a second layer of paper can help. As always, we recommend lubing conical bullets. While the powder charge is enclosed within the cartridge, the benefits of a softening lube layer remain—especially when using black powder substitutes like Triple Seven. Cleaner fouling means easier follow-up shots and less barrel maintenance.

Paper cartridges can be tricky in traditional sidelocks. The ignition spark often isn’t hot enough to fully ignite the paper without a little help. Be sure to prick the cartridge base and allow a bit of powder to settle into the breech. Once lit, the rest of the cartridge will burn reliably. Always test your procedure before heading into the field to ensure dependable performance.

Standard .490 swaged roundballs (e.g., from Hornady) work well with paper cartridges. In sidelocks with 1:66 twist rates, paper wrapping may even improve spin and consistency compared to traditional cloth patches. While formal accuracy tests, anecdotal results suggest the paper wrap can enhance stability. Adjust the number of paper layers based on your bore fit and any signs of gas blow-by.
