Re: What is your favorite 300 Win Mag load?
The second load I tried, 20+ years ago was a Hornady 165 gr. flat base, Win 8½ primer and 80 grains of H4831. It was right out of a book, but I don't remember which one, right now? Never tried anything else, still puts 5 under a quarter @100 yds. Recent data claim it's a hot load, so be careful.
Good hunting. LB
