Thanks for the responses.
John I have your book "Rifle-Troubleshooting and Handloading" and read through the chapter you pasted a couple of times over the last few days. I've enjoyed the book and have learned much from it.
I just wasn't sinking in but I see now that even though the bullet/powder are the same, the primer/case for the loads in the Hornady vs. Lyman manual are different.
Up to now I've followed the Hornady guide pretty much verbatim but with components being harder to get I haven't been able to find exactly what I've used in the past and have had to venture outside of what I know.
Thanks again.
