My first Lyman .38 Caliber bullet mold was the 358311. Have lots of fond memories putting it to good use. However I soon got the .357 Magnum bug....that forced me to go to SWC cast bullets and the 358311 saw little use. I also started using a 358495 WC cast bullet in the .38 Special. These days I still load up a size-able quantity of .38's with the 358311 ... for old time sake. I have heard that others find that it is the most accurate .38 Cast bullet in their pistols. I have found it not to wanting when it comes to accuracy. The only drawback is that it doesn't make clean hols in p-targets. However I seldom shoot paper... I was wondering how others feel about using it.
