Loaded my first batch of 38 Specials today. Started with the online Hodgon's reloading data. I am using Zero 125gr JHP, and Winchester 231. I made couple handfuls each with 4.5gr and 4.8gr of powder charge. OAL is 1.440' and crimp 0.375". According to Hodgon's I should be getting 1071 ft/s for the 4.8gr load, which is at the top of their range. I was expecting a little over 900ft/s for the lighter load I made. With the F-1 Chony, I got 750 ft/s for the 4.5gr loads, and 850ft/s for the 4.8gr out of my 4" Python. Both with SDV of about 20ft/s. Accuracy was good at 15ft. But I was expecting to get more velocity. I think I am going to push it to 5.1gr. Care to share your load data?
