Lee Double Cavity Bullet Mold TL309-230-5R .309" 230gr Aluminum

The Lee Double Cavity Bullet Mold TL309-230-5R (part 90307) is a precision CNC-machined aluminum bullet casting block made for handloaders who cast their own 30 Caliber rifle projectiles. This double cavity configuration drops two finished boolits per pour, doubling output over a single-cavity mold and making it a practical choice for high-volume casting. The lightweight aluminum blocks come up to pouring temperature quickly on the lead pot, so you spend less time waiting and more time casting clean, repeatable bullets.

Each cavity casts a .309" diameter, 230 grain bullet in Lee's 5R round-nose profile - a heavy, multi-banded design that has earned a strong following as one of the quietest, most accurate subsonic projectiles for the .300 AAC Blackout when driven from a fast-twist barrel with a reduced powder charge. The driving bands and crimp groove are well-suited to standard cast-bullet lubrication with Lee Liquid Alox or equivalent, and the finished boolits feed reliably through standard 30 Cal magazines. Casters run this design in plain lead, classic wheel-weight alloy, or harder formulations for the velocity and penetration needed for hunting or range use.

This Lee mold ships complete with the matched pair of CNC-machined mold blocks, a set of wooden handles, and a sprue plate - everything required to start casting except the lead, the ladle, and the lube. As with all Lee production molds, the cavities are cut for consistent bullet weights and clean release, and the .309" sizing matches the bore diameters commonly used by 30 Caliber cast-bullet shooters. Whether you are loading quiet subsonic .300 Blackout rounds for the range, building economical cast-bullet practice ammo, or producing heavy projectiles for deer-sized game, the Lee TL309-230-5R delivers the accuracy, consistency, and value expected from a trusted American reloading brand, proudly made in the USA.
