Lee REAL molds are less than $25 from places like Track of the Wolf. Generally, they shoot accurately assuming you select the one that is right for your gun. The .45, .50, and .54 caliber REALs are made in two lengths, (or weights) The shorter of the two works well in slow-twist rifling and the longer ones work better in guns with a faster rifling twist. I cast mine from pure lead at around 850 degrees to get a good fill-out. They are easy to load and shoot best with a 1/8" card or felt wad between them and the powder charge. They are quite effective on big game.
