This being said, you should be fine following the load data for 158 grain RN bullets. Begin near the starting load and work your loads up. In the past, I have used data for 158 grain SWC's with my cast 150 grain SWC's and all went well.

Your OAL should be about the same for 150 or 158 grain Round Nose bullets in .38 Special.

Good luck
Thanks guys. I love this forum. Wouldn't know what to do without it
