Re: New Gun, New Scope might start reloading looking for advice.
As far as the manuals go, I'm with the guy that said to get one for the brand bullets you use. In addition to that, I suggest you pick up the manual produced by Lee precision. Although not regarded with as much authority as the Lyman, it does a great job covering the basics and it has WAY more information about different powders. Lyman, hodgdon, Berger, nosler, hornady, Speer and the rest have great information and cover the powder which should work best for a given cartridge, they don't cover all the possibilities. I bought the Lee manual because they cover powder which can be safely used with a given cartridge/bullet weight combination and if the shelves are as bare in your neck of the woods as they are in mine, you may find yourself having to develop a load using a powder you wouldn't typically prefer to use. If you're lucky, you'll stumble upon an unusual load that miraculously gives amazing results. Prime example: I didn't want to use up my preferred powder doing seating depth tests for Berger vld bullets in my .300wm and stumbled upon a load using h4895. Although it isn't an ideal powder, I not only found the jump my rifle likes, but have been consistently shooting .5 MOA. Just food for thought.
