I can't seem to find any data that matches the bullets/powder I have on hand at the moment, but there ought to be something that will work for this combination. Just looking to see what wisdom you guys might be able to share, or to see if you know anywhere that this data might be written down!
I've got a box of 250 HSM 9mm (.355) 124 grain round nose plated bullets on hand, and about a pound of Power Pistol powder. For the life of me I can't find data for this particular load (it's not on Alliant's website or HSM's site, or in any of my manuals). I also can't reliably find any components in the local stores these days, so this stuff will have to work together for the time being.
Now, my Lyman load manual shows a 130 gr RN FMJ bullet with a COAL of 1.160" and 5.1-5.7 grains of Power Pistol. It also shows a 120 grain RN lead bullet with a COAL of 1.065" and 5.0-5.6 grains of Power Pistol. Since I'm shooting a plated bullet I figure it might fall in between these two.
I also have some loaded ammunition (hand loads) with 4.7 grains of Power Pistol and a COAL of 1.155", which I put together using this bullet based on load data that someone gave me (and I've since lost)... but, those rounds didn't cycle well during my range test (unknown reason, but no pressure signs).
Where would you begin on this problem to come up with a viable load?
I know the 9mm is susceptible to pressure rise with too-deeply seated bullets, so the COAL concerns me more than anything I suppose. Still, I'm thinking somewhere around 1.11" COAL and 5.0 grains of Power Pistol ought to be a safe starting point? I don't normally load without data available, and obviously don't want to play cowboy and end up explosively disassembling a gun (or my hand).
Thanks!
