RCBS Flat Nose Rifle Bullet Mould, Double Cavity, .458 in, 300 gr

The RCBS Flat Nose Rifle Bullet Mould (brand part no. 82051) is a double-cavity mould that casts a flat-nose rifle bullet, the traditional choice for tubular-magazine lever-action rifles since the flat tip won’t set off the primer of the cartridge ahead of it, true to .458 in diameter at 300 gr. Like every RCBS mould, the blocks are machined from solid cast iron to exact specifications, so bullet casters get clean, consistent castings session after session rather than fighting flashing or short-fills. It’s built for handloaders who cast their own lead bullets rather than buying jacketed or plated projectiles, and it drops straight into any standard mould handle setup.
