The RCBS Flat Nose Rifle Bullet Mould in single cavity .446" 370 grain is a cast-iron casting tool built for shooters and reloaders who want to produce their own rifle bullets without breaking the bank. If you're into handloading—whether you're working with custom cartridges, historical rifles, or specialty applications—a quality bullet mould is foundational. This single cavity design lets you cast bullets one at a time, giving you full control over the process and the finished product.
RCBS has engineered this mould from solid cast iron blocks, paired with a 3/16-inch solid steel sprue plate and hardened steel spring washers and screws. That construction approach means the mould holds its tolerances shot after shot and resists wear. The casting cavity itself is ground to a precision square, meeting strict specs so every bullet cast from it comes out consistent. That consistency matters when you're handloading: slight dimensional variation can affect velocity, accuracy, and pressure curves downrange.
This is a working tool meant for the long haul. Single cavity moulds aren't the fastest option if you're casting thousands of rounds, but they're reliable, easy to manage, and ideal for smaller batches or when precision matters more than volume. If you need a handle—some shooters prefer to add their own or upgrade to a custom handle—you can purchase one separately at a modest cost.
| Caliber/Diameter | .446" |
| Bullet Weight | 370 grains |
| Cavity Count | Single |
| Body Material | Cast iron |
| Sprue Plate | 3/16" solid steel |
| Fasteners | Tempered steel spring washers and screws |
Handles are sold separately, so you have the option to add one or use your own. This lets you choose exactly the handle style that works best for your setup.
This specific mould casts .446" diameter bullets weighing 370 grains. If you need a different caliber or weight, RCBS offers moulds in a number of different configurations.
This is a single cavity mould, meaning you cast one bullet at a time. It's designed for controlled, precise work and smaller batches rather than high-volume production.
The mould is machined from solid cast iron blocks with a precision-ground cavity that meets strict specifications. The 3/16-inch solid steel sprue plate and hardened steel fasteners are built to hold tight tolerances and resist wear, so bullets remain consistent shot after shot.
