This is a hard to find Lyman #358446- 4 bullet mold for 357/38 cal SWC that was developed mainly for 357 loads. For more info look up an article in The Los Angeles Silhouette Club by Glen E Fryxell that cornicles it's history, and the design. In the article, they have phots of the bullet and as a loaded 357 round. This is a used mold, but great condition, that the pictures show. I have not found this particular mold for sale new anywhere. Please ask any questions before bidding, thanks
