I also load for the 38 S&W. The bullets eddie76 recommended are very good. I also load a 170gr bullet from The Western Bullet Company. Most .38 S&W revolvers shoot very well with a 145/146gr bullet but they should be .360"/.361" in diameter, not .358". Accuracy with .358" bullets can be poor and leading is more problematic.
There are several casters online who sell the correct bullet but the Missouri Bullet Company is a good choice IMO. The sell them with or without Hi-Tec coating. They also sell 100 piece sample packs if you want to try something without buying 500.
