Huntingnet.com Predator Hunting Reference Section
Take a look through this section of the forum (link at the top of the page on the Small Game forum also).
The reference section has a lot of tips and guidance for new hunters, and is a place where you can ask specific questions for some of us to answer as well. We keep certain topics over there because we get a lot of repeat questions, so that's a place that can store info long term for lots of new guys to read.
My advice on hunting with that .308win is to use your typical deer hunting bullet, or at least a fairly hard deer hunting bullet. I've never seen a benefit in using lightweight bullets in a 30cal in terms of fur-friendliness. A "firm" deer bullet like the Hornady SST or Interbond, or a bonded Partition will leave two holes, as most 30cal bullets will, but the exit will be nice and small, instead of a gaping mess like a lighter construction bullet would make.
