RCBS
The RCBS Cowboy Bullet Mould in double cavity configuration lets you cast .258" diameter bullets at 85 grains—ideal for handloaders who want to produce consistent cast projectiles for cartridges like the .257 Roberts or similar rounds. Built from solid cast iron and precision ground square, this mould delivers the accuracy and repeatability you need whether you're working up loads at the bench or casting rounds for extended range sessions. The double cavity design doubles your output compared to single-cavity moulds, so you spend less time at the casting pot and more time at the range.
RCBS engineered this mould for long-term durability. Steel alignment pins keep the cavity blocks firmly registered shot after shot, even after years of use. The 3/16-inch solid steel sprue plate is secured with tempered steel spring washers and screws, holding true under the heat and pressure of the casting process. The precision-ground surfaces ensure that each bullet exits clean and requires minimal finishing work before loading.
This is a mould only—handles are sold separately and are available at reasonable cost. If you're already set up with RCBS casting equipment or plan to build a casting station, this double cavity mould is a practical choice for boosting production of medium-weight cast bullets.
| Bullet Diameter | .258" |
| Bullet Weight | 85 Grains |
| Cavity Configuration | Double Cavity |
| Material | Cast Iron (precision ground) |
| Sprue Plate | 3/16" solid steel |
| Alignment System | Steel pins |
| Handles | Not included (sold separately) |
RCBS bullet mould handles are sold separately and are designed to fit standard RCBS double cavity moulds. Check RCBS documentation or your local dealer to confirm the correct handle part number for your setup.
This mould is designed for hand casting, not for use under press pressure. You'll need a proper casting setup with a lead pot and thermometer. Handles are purchased separately and attach to the mould for manual casting at the pot.
RCBS cast iron moulds with steel alignment pins are designed to hold up to years of regular casting. The precision-ground surfaces and steel pins keep the cavity blocks in proper alignment shot after shot, and the solid construction resists wear from repeated heating and cooling cycles.
This mould casts .258" diameter, 85-grain bullets suitable for cartridges that use .258" projectiles, such as the .257 Roberts and similar rounds. Always verify bullet diameter compatibility with your specific cartridge before loading.
