I searched and couldn’t find just what I was looking for so here it is...
I’ve been casting for subsonic 300 blackout with straight ww’s and pcing them. Thing is, I have a couple hundred lbs of pure lead. What ratio is gonna give me a useable hardness for my needs? I don’t have a lot of free time to experiment. If there’s a resource I don’t know about, feel free to share it with me.
