I use to use one a lot but haven't for many years. I generally use Barnes bullets and their data at near max, play with bullet seating a bit tip and get all I need to hunt with. With my handguns I load my big bores moderately and my smaller bores a bit under book (usually Hodgdon) max and I am good to go as well. I do not partake in the long range stuff.

Conduct is the best proof of character.
