If you cast your own rifle bullets, the RCBS Flat Nose Rifle Bullet Mould in .321" 170 grain is a workhorse double cavity mould built for serious reloaders. This is a traditional cast iron mould engineered to deliver consistent results shot after shot, whether you're loading for hunting, target practice, or historical rifle cartridges. The flat nose profile is ideal for lever-action and straight-wall applications where a blunt bullet design offers reliable feeding and terminal performance.
RCBS built this mould from solid cast iron blocks paired with a 3/16-inch solid steel sprue plate, the kind of no-nonsense construction that rewards years of dedicated use. The mould features tempered steel spring washers and screws that hold up to repeated casting cycles without loosening or wearing out. Each mould is ground to a precision square and meets strict manufacturing specs, so you get uniform bullet dimensions and weight from cavity to cavity. That consistency translates directly to tighter groups and fewer unexplained flyers downrange.
The double cavity design cuts your casting time in half compared to single cavity moulds, meaning you can produce ammunition faster without sacrificing quality. If you don't already have handles, RCBS offers them separately at low cost, so you can customize your setup to fit your bench and workflow. Whether you're reviving an old rifle cartridge or optimizing a handload for a hunting rig, this mould gives you the control and reliability you need to produce ammunition you trust.
| Caliber | .321" |
| Bullet Weight | 170 grains |
| Cavity Configuration | Double cavity |
| Material | Cast iron blocks, steel sprue plate |
| Bullet Profile | Flat nose |
The .321" diameter and flat nose profile suit lever-action rifles and straight-wall cartridges designed for that bullet diameter. Confirm your specific cartridge's bullet diameter and profile recommendations before ordering.
Handles are not included with the mould but are sold separately by RCBS at low cost. You will need handles or a mould block to safely hold and operate the mould during casting.
RCBS designed this mould with solid cast iron construction, precision ground components, and tempered steel fasteners to provide years of reliable service when properly maintained and used.
This is a double cavity mould, meaning it produces two bullets per pour cycle, cutting casting time roughly in half compared to single cavity designs.
