Question. In my 47th edition of my Lyman reloading manual looking at load data for 9mm lead bullets the nearest to the lead I want to load (124gr RN and 126SWC) is 121gr RN bullet which is under and a 130gr truncated cone. I was thinking about W231.
For the 121gr they show min max 2.9/4.4 for the 130gr they show min/max 2.6/4.1
Ive looked in my other manuals and nothing specific to 124 or 126gr lead bullets.
What's a safe approach to choosing my starting weight? They will be shot in a Glock 34. I'm thinking a beginning weight of 3.5gr's. for both the 124gr and the 126gr.
These will be the first 9mm I have worked with so Im open to suggestions. The bullet are a .357 dia from Dardas Bullets and are a first try at lead in this gun. The barrel slugged at .356/.3558 BHN 16
Thanks
