nhglyn Posted February 28, 2020 Share Posted February 28, 2020 I will be starting to load 9mm with Montana Gold 147 gr flat point bullets. For those using this combination, what do you use as an OAL? Same as round rose bullets? Shooting out of Springfield XDM 5.25. Many thanks. Link to comment Share on other sites More sharing options...
