I think pretty much all of the bullets out there nowadays will get the job done if you

1. Select the proper bullet weight for the game you are hunting
2. Use the proper powder charge for that bullet
3. Put the bullet through the lungs or heart

Although #3 is the most important of them all. A lot of people use Powerbelts successfully - some of the guys I hunt with do. But personally, if I were to use them, I would use a heavier weight powerbelt with a reasonable powder charge (70 - 90 grains).
