For me, it started with the fact that I could shoot at 3 out of 4 species during rifle season, before everything started gravitating towards going on draw. In a lot of the foothills zones you never know if a 3pt elk will suddenly make an appearance. Deer don't need premium bullets, but, a hard quartering elk or moose shot is something that needs to be allowed for. Then it is nice to have a little insurance and confidence in a premium bullet.
