By "hunting" rifle, I'd assume you mean factory rifle/chamber/barrel?
I wouldn't expect any dividends by going to the arbor system at all. You'd be miles ahead/better served by buying the best brass possible for your chamberings, a runout gauge and dies if warranted. If all is well, a LEE loader could be perfectly fine for a hunting rifle.
Arbor setups don't get attention from even the most sick accuracy freaks until a rifle system is built around them.
