I load all my 9mm to 1.130 OAL regardless of the powder used. When asking questions when I first stated loading the 9mm, many stated that was the OAL they used cause just about any Glock or other 9mm with devour them at that length. I have to agree at this point after my own experamentation
I start at the minimum data cross referencing several sources and work up from there. The OAL for you factory loads may not work with the Berry's RN profile. Also, are you case gauging your completed rounds?
