I'm looking at reloading Sierra GameKing 165 gr (#2145)
Checking different books show dramatically different load ranges.
Example IMR4895:
Lee Book shows starting 42.7 and max 45.5
Sierra Book shows starting 38.3 and max 41.9
Viht N550:
Lee shows starting 44.1 and max 49.3
Sierra shows 40.7 to 46.7
How do you determine which book to go with? Do you go with the actual bullet manufacturer's book as the authority? That's what I'm leaning towards.
