The RCBS Flat Nose Rifle Bullet Mould in .458" 300 gr is a double-cavity casting tool built for handloaders who want to produce their own big-bore rifle projectiles at a fraction of commercial ammunition costs. Whether you're reloading for a .458 Winchester Magnum, .458 SOCOM, or another large-bore rifle cartridge, this mould lets you cast consistent, quality bullets in volume—two at a time—without the premium price tag of factory ammo.
Built from solid cast iron, this mould is engineered to handle the demands of serious reloading work. The 3/16-inch solid steel sprue plate and tempered steel fasteners are designed for years of reliable service, and the mould is ground to precision square to ensure dimensional consistency between cavities. If you're casting 300-grain flat-nose projectiles regularly, a double-cavity mould cuts your casting time in half compared to single-cavity alternatives, making it a smart investment for volume shooters.
RCBS moulds are known for holding tight tolerances and producing uniform bullets—critical for accuracy and consistent feeding in rifle chambers. The flat-nose profile is favored by hunters and shooters using lever-action rifles, dangerous-game rifles, and other platforms where the design offers reliable performance. Handles are sold separately, so you can configure your setup to fit your casting bench and preferences.
| Caliber / Diameter | .458 inch |
| Bullet Weight | 300 grains |
| Cavities | 2 |
| Bullet Profile | Flat Nose |
| Primary Material | Cast Iron |
| Sprue Plate Material | Steel (3/16 inch solid) |
| Fasteners | Tempered Steel |
The .458" diameter is used in cartridges like the .458 Winchester Magnum, .458 SOCOM, and other large-bore rifle platforms. The flat-nose design is particularly popular for lever-action rifles and dangerous-game rifles. Always verify that the bullet dimensions and profile are appropriate for your specific rifle and cartridge before casting.
Yes, handles are sold separately for this mould. This gives you the flexibility to choose a handle style that fits your casting setup and preferences, or to use it with a mould handle block if you prefer.
This is a double-cavity mould, meaning it casts two bullets per cycle. This significantly speeds up production compared to single-cavity moulds, making it ideal for shooters who cast in volume.
We've provided only the mould specifications. For lead alloy recommendations and casting best practices, consult the RCBS documentation or reloading manuals specific to your cartridge and bullet design.
