New to reloading have most of what I need in tools and equipment . Lacking knowledge in a lot of areas. Specifically 9 mm with titegroup and Hanson 125 grain coated bullet and seating depth. Not looking for anything to be dangerous just a decent load for shooting those pesky paper targets ive read enough to get an idea about cup pressures. I can't seem to find a seating depth that is written in black and white as I've heard titegroup can be somewhat unpredictable with 125 grain loads under or over two or three tents with specific seating depth. Am I trying to be too scientific or is there any guidance I can get from someone out there. So that I am making bullets not hand bombs. Thanks not for any help TerryD.
