I've done a copy & paste from Accurate Arms Load Manual 6.0 for your Berry's bullet. Long ago in my foolish youth, I shot Lee 255 SWC bullets for bowling pin matches. I know a little about heavy bullets, a little about AA #5, and believe you will get the load you want with the starting charge. I was using Hodgdon HS6 powder. It was published data and quite brisk! ! !

You can Google "Accurate Arms Load Data" and find the entire PDF file. I downloaded it to my computer and have the paper manual 2nd Edition.
