I am struggling to figure out load data for 147gr Blue Bullets. Apparently there's not a lot of load data available for this setup. Which I didn't realize before I bought a bunch of bullets.
I picked up HP-38, but from what I can tell, some think it's too fast a powder for the 147gr.
Does anyone have a recommendation for powder to use? And a safe starting point? I plan to make up 10 in varying powder increments (10 at each increment) and chrono it. I just don't want to blow up my gun (or my hand) in the process.
