So, through a friend of a friend, I have happened into some free bullets to try out when reloading. I am being sent some 124gr RN 9mm and some 180gr FP for .40/10mm, both of which are lead. The only problem is that I don't have any data for either one of those in any of my books (Hornady 9th, Lyman 49th, Lee 2nd, and a Load Books for 10mm). I also referenced HodgdonReloading.com, no dice for my specific bullets.
I do have data for some bullets which are close. I have 125gr lead 9mm data. I seem to remember learning that it's ok to use the next heavier data, just start at the minimum and work up. Is that right?
For the 10mm, it's something completely different. I have data for 180gr jacketed and jacketed FP, 175gr LSWC, 175gr lead with Lyman mold #401043, and 180gr LSWC from Hornady (#10808).
So my questions are: is it safe to use 125gr data for 124gr bullets, just start at the minimum and work up? And, is it safe to use any of my 10mm data listed for what I am going to get in the mail? My initial thought is the Hornady lead data would be my best bet, but what has me spooked is the profile isn't the same.
Not sure if this is important, but I'd prefer to use 700X or TiteGroup. I have plenty of those two powders.
