The Lee Round Flat Nose Rifle Mould in .457-diameter, 340 grains (brand part no. 90373) casts a lighter flat-point option than Lee’s heavier .457 offerings, giving .45-caliber lever-gun shooters a bit more velocity headroom for the same bore diameter. It’s sized for .45-caliber rifle cartridges, and the flat meplat is a functional feature built for safe feeding through tube magazines. Lee Precision has produced affordable, patented reloading tools since 1958, and every mould in this line is cast, machined, and assembled in the USA.
