The grain refers to the mass of the projectile, not the powder charge. The higher grain will actually have a lower muzzle velocity.
Typically, the lighter factory rounds you will find are varmint rounds and should not be used on medium-large game. The heavier rounds will be constructed to hold together better and are better suited to deer sized game.
For just target shooting, use different types and see what your gun likes, but remember, contrary to what you are currently thinking, faster is not always better (and rarely is it 'best').
