I reloaded my first batch of 9mm, and I want your advice. I made 18 rounds of 115 gr. round nose, Berry plated, Hodgdon Universal 4.2gr, OAL 1.156. I arrived at the OAL after measuring one of my factory UMC rounds. I am not sure what OAL to set. They fit fine in my gage. Range report. I had one failure to chamber. When I dropped the magazine and ejected the round, I saw that the plating got scratched up in the process of chambering. I wondered if it failed to feed because of the OAL or possibly because the low charge (4.2 gr of Universal) failed to move the slide adequately enough. The other rounds worked fine. I am using the deluxe press from Lee and the dispenser seems to not be 100% accurate. I made another lot with the same diameter and powder charge and I will shoot them later this week. Should I change the AOL on them? I believe making them shorter will increase the pressure and the velocity. I dont own a Chrony. My Lyman 49th Ed manual gives only the Max OAL, and the Hodgdon data from the website does not give OAL either. What do you think?<!-- google_ad_section_end --> Wanna kill these ads? We can help!
