Are you looking for plinking or hunting? Plinking- I go cheapest I can find. Hunting for coyotes I will use CCI stingers. Hunting small game I like CCI or Remington. Best thing to do is do some bench testing in your gun and find what it likes. No two guns are the same.

In centerfire rifles, when reloading, sometimes 0.5 gr of powder can make all the difference in how your gun groups with a specific bullet. There are litterally thousands of combinations for bullet, powder, primer, and seating depth combinations for a given caliber.
