It seems newer reloaders are drawn to "one caliber" load "books". IMO big mistake. I haven't looked at the Lyman one caliber books, but I highly recommend a regular, published reloading manual, as there is a lot more info than just reload data in them. I just glanced at my Lyman 49th (I keep my 49th on my desk and my 50th in the shop along with my other manuals). The 49th has 9mm data for jacketed bullets from 90 gr. to 147 gr and cast bullets from 90 gr to 147 gr. I have reloaded a lot of RMR bullets in 9mm and have safely used the data right out of my Lyman manual. I use plain old common sense; I choose a bullet of the same general weight and profile, begin with starting loads, and plunk test. If necessary, I increase the velocity until I get an accurate load that functions well in my gun.
The reloading manuals I use most often, in no order;
Lyman 48th, 49th, 50th.
Lyman Cast bullet handbook, 3rd and 4th
Speer #11 and #15
Hornady 9th, 10th.
Nosler #8.
Hodgdon annual, current edition for 2020.
I also a few others some from the '70s, '80s and even a Lee manual but the above are used first...
BTW; I ignore any load data I see on any forum, pet loads website, or hear from any gun counter clerk, range rat, well intended friend, or gun shop guru. I get my data from published manuals and occasionally powder manufacturer's web sites. Since 1969 I have had one squib and zero kabooms...
