I have forever used the Lyman 358156 in 38 and 357, was majoriyt of my shooting regarldless, but due to increase in gas check prices, I tired the Lyman 358 Cowboy, 358665, damn have I been impressed. I'm not necessarily fan of Lyman but have used dozens of their moulds, you might want to try this 158 RNFP 665 mould. It has been a delight far as accuracy is concerned in rifle and pistol for me. I have a 358311 4 cavity mould that shoots great too, this CB Mould seems to be RNFP version of that old favorite and I can use in rifle too.
