I use Nosler latest (#6). I have others from Speer, Barnes, Hodgdon and Lyman. Plus, in addition to all those, I have several internet sites that I have stored in my Favorites under "Reloading".
I probably shoot more Ballistic Tips than any other bullet. Nosler's information in usually spot on for me. I compare them all against each other when I first start working up a load. JohnnyK.
I use Hogdon's web site to find a range of powder burn rates for a particular cartridge, and a good start point. I look for the powder that gives the best vel w/ the lowest pressure, and a nearly full case.
Actually the correct answer would be,,,
All of them.
I own all the manuals because the data that you will get in each one will be with that companies bullets and there test gun. And I have and do read all the reloading information that they come with. You never know what and where you will learn from.
For me my favorite Long gun: Hornady
I chose other because I use several and always run the range of loads through Quickload. I suppose if I only had to choose one, it would have to be quickload and then just verify the load data via the free online powder/bullet websites.
If some is good and more is better, then too much is just right.
My mind is a raging torrent, flooded with rivulets of thought, cascading into a waterfall of creative alternatives
I think, first of all, that its important to remember these are "guides". Swift, which my gun likes the best, is my book of choice. I do, like most I would imagine, tend to take a little information out of a lot of the manuals and find out what works best. The numbers provided in these books are good starting points, nothing will ever make up for performing your own RND.
