I loaded my first .38s yesterday. I have been loading 9mm, 380, .40 S&W and .45. All of these take lots of Unique powder. The 9mm takes 5.4 grs for a 115gr round. This fills the case and actually compresses some under the round. The .38 on the other hand takes 4.4 gr of Unique for 158 gr bullet. There is a lot of empty space in the case. Curious!
