I'm sorta new to the reloading... But from a lot of help from the guys on this forum, I've manage to get some pretty decent groups from my 300 mag

I know the basics...

But I want to take it to the next level... I want to know if there are any good books out there that can help me do this???

I have one of each....and have gained a different bit knowledge from them.

The folks at Sinclair's are pretty helpful when you get into stuff like outside neck turning and loading for competitive shooting.

you can get free reloading booklets
from ammunition companys
post an addresse and phone number
and ill try to get you some

I think you should be a little more specific about what your trying to achieve. Sometimes just changing dies can make a world of difference.
