Basically, any decent powder for the .30-06 works with a 165-grain bullet, and the Hornady is one of the most forgiving bullets because of its soft jacket and shape. The Hornady is a great all around choice for targets and hunting, though it is considered a bit on the soft side for really tough game.
I have found that 50 grains of Varget is a superbly accurate load with a 165-grain bullet, and it works with any action. This is what I use in my Garand. It usually produces between 2,750 and 2,800 fps velocity, depending upon the barrel. It's about as close to the universal .30-06 load that you can get.
The classic bolt action load, as suggested above, uses a maximum charge of IMR 4350. That load just plain works, and you can't go wrong with it. (Slow powders like this should generally only be used in bolt actions or similar rifles.)
I've also had great results in bolt rifles with H4831SC, Reloder 22 and Vihtavuori N560. You can't put enough of these powders into a .30-06 case to cause a problem, and I have found them to be remarkably consistent, giving great velocities with normal pressures. For these reasons, these are the powders I use for hunting loads.
Other great choices are Reloder 19, H414 and similar powders. I've never tried Reloder 17, but I hear it is phenomenal in the .30-06.
IMR 4064 still has its fans, as does Ramshot Hunter (though I've never yet tried any Ramshot powder).
You get the idea. It is generally prudent to start with the classics and then experiment with others after that if you are unsatisfied.
