Picked up a 10.5” pc a week ago. I’m waiting on brass and bullets to show up. I’ve ordered the 390gr spires, 380gr wfn, and 440gr wfn to try.
I have aa9, 2400, 296, and imr4227 for full power, have unique for the dinkers. I have a few faster rifle powders, but I don’t want to waste them on this.
My hornady book is the only thing that shows imr 4227 and 2400 loads for anything over 350gr. And that’s a 500gr jsp. My Lyman 50th shows data for h4227, but I’m leery mixing data, I’ve heard h4227 and imr are ok to mix if you start at the minimum and go up, but I’m hesitant.
Anyway, could I use the 4227 and 2400 starting data for the 500gr in the book to start on the 440gr being these two powders can be downloaded somewhat and are just nasty vs going kaboom, then work up? The 296 and aa9 data is everywhere for each bullet I’ve ordered, so no concerns there.
Thanks in advance.
