Gary Scott Dale asked:
What other brand books ought I purchase?
Purchase as many loading manuals as you like.
The important thing is NOT how many manuals you have, but whether you're read ANY of them.
Before flipping back to the charge tables, take an evening to read - no, not read,
study - pages 32 through 57 which will tell you "How to Reload". And when you're done, go through it a second time. Commit it to memory.
You will be tested. The test comes when you start assembling these little pipe bombs we call cartridges and how well you have learned your lessons will determine whether your nickname is "Sharpshooter" or "One Eye Jack".
There's currently another post active here where someone is asking a question answered on page 39 of the Hornady Handbook - page 39 all the way back to at least the 8th edition. That strongly suggests the OP didn't read the "How to Reload" section. And that's where people get into trouble.
Study the "How to Reload" section. Reduce what you learn into a set of written reloading procedures. Turn that into a checklist. Check off each step AFTER you do it. That way if you get distracted or interrupted, you will know where you left off.
Don't be in a rush. Getting into a rush is where mistakes are made. You have the rest of your life to craft the perfect ammunition.
Good luck.
