Rcbs Cowboy Bullet Mould - Double Cavity .309" 150 Gr

The RCBS Cowboy Bullet Mould in double cavity configuration lets you cast .309" 150-grain bullets efficiently for your reloading bench. Whether you're setting up a casting operation for the first time or expanding an established setup, this mould delivers the precision casting that RCBS has built its reputation on. The double cavity design means you're producing two bullets per cycle—a meaningful speed boost compared to single-cavity alternatives, especially if you're casting volume for hunting or range sessions.

Built from solid cast iron and precision ground square, the mould maintains tight tolerances that translate directly into consistent bullet dimensions. The steel alignment pins keep the cavity blocks firmly registered through hundreds of casting cycles, so you're not fighting shifting alignment or dealing with the frustration of binding blocks. That kind of reliability matters when you're committed to the handloading process—you want your tools working as hard as you are.

The 3/16-inch solid steel sprue plate handles the job of separating cast bullets cleanly from the ingot. It's held securely in place with tempered steel spring washers and screws, so the plate stays put under repeated heating and cooling cycles. Note that this mould ships without handles; RCBS offers compatible handles separately, letting you choose the style that fits your casting rig.
