I shoot a Savage 10BA in .308 and have excellent results with Sierra 180gr in a 1-10" twist.
I just bought 500 168gr matchkings to try next.
I however use Hodgdon Varget which is very temerature stable.
Don't assume that a load you develop at -30F will be safe at 90F
You will soon begin to collect a bunch of different reloading manuals which will grow into your own data library over time.
Here is the link to Sierra's data.
