The Lee Round Nose Rifle Mould in .459-diameter, 500 grains (brand part no. 90577) is a double-cavity, handle-equipped mould built for reloaders casting heavy, big-bore rifle bullets. It’s sized for .45-caliber rifle cartridges, and at 500 grains it’s one of the heaviest castings in Lee’s handled rifle mould line, suited to big-bore lever guns and large-caliber rifles. Cast from aluminum block halves, it heats and cools far faster than an iron or steel mould, resists rust in a humid range bag, and stays noticeably lighter through a long casting session at the pot. The block halves are crimped at the factory, so cavity alignment stays tight pour after pour, and every bullet drops from the mould round and correctly sized.
