Federal, Hornady and Winchester have all been the best off the shelf, some perform with different bullets better than the other I just let my gun tell me which brand to use with the bullet style I want, need and require for the game I am hunting.

Let your rifle and the situation(game, terrain, etc) dictate what to put in the pipe, it is always the best way. I also think practicing with the bullet you intent to use is a must, it just breeds confidence. Of course if your just shooting for the heck of it, sure buy cheaper stuff but when it comes to preparing for a hunt spend the extra money to practice with what you are going to be using come open bell...just my 2 cents worth[:-]
