The Lee Round Flat Nose Rifle Mould in .457-diameter, 450 grains (brand part no. 90375) sits between Lee’s 405- and 500-grain offerings in the same bore, giving .45-caliber lever-gun shooters another heavy-bullet option to fine-tune trajectory and recoil. It’s sized for .45-caliber rifle cartridges, and the flat meplat is built for safe, reliable feeding through a tube magazine. Lee Precision has produced affordable, patented reloading tools since 1958, and every mould in this line is cast, machined, and assembled in the USA.
