Scootertheshooter Posted April 3, 2020 Share Posted April 3, 2020 I run 4.4 of HP-38 with a 124 at 1.13 with a G34 and get 1094 FPS . That barrel does run a bit faster with the rifling . 231 and HP-38 are the same powder Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Cfish Posted April 3, 2020 Share Posted April 3, 2020 4.8 would be a good starting load for that bullet. Link to comment Share on other sites More sharing options...
