Re: Help please
I can't answer 1 or 2, but as far as not being able to use magnum primers with 2400, the Lyman 49th edition page 357(oddly enough) states using CCI 550 primers, and lists using 2400 in 11 out of 14 loads. In fact, it's listed as the "most accurate" in 5 of them.
Quote from the book:
"For light loads Bullseye works best. Heavy loads work well with a wide range of powders but you might want to try 2400 for your first accuracy tests."
I only have the Lyman in front of me at the moment to referance.
I highly reccomend adding the lyman manual to any reloading library, it's not brand specific as far as components, but as usual, its better to have a few different manuals on hand, even editors make mistakes.
