How close do 45 cal. Lee molds run to the diameter listed? I am interested in purchasing two Lee molds for use in a .458 Win. I like the C457-500-F design for the business load, as it is a 500 gr RNFP GC bullet. For an intended less punishing, and most frequent use, I sort of like the 457-340-F, a flat base 340 RNFP, and would like to load around the 1500fps range.
These molds are listed at .457 nominal diameter, and I am going to need at least a .458, or preferably a .459 diameter bullet for the .458 Win. Lee does make 2 molds that are listed at .459, but they are not the profiles that I want. I tried calling Lee for info, but their lines are always busy.
Lee molds are inexpensive, and I don't expect to do a whole lot of casting with them, as I don't expect to fire this rifle a whole lot, it's the reason I am considering these molds.
In case anyone was wondering, why a .458 Win, I was made an offer I could not refuse, on purchasing this particular rifle.
