Here are the specs below from Cabela's, I put my notes on the end of each line. All CCI loads.
The .17 HMR 17-grain Speer TNT® Hollow Point has a 2,525-fps muzzle velocity and delivers about 179 pounds of energy at 50 yds. - Good for small game, not as violently disruptive as the polymer tips, but still pretty reactive at short range.
The .17 HMR 17-grain V-Max has a 2,550-fps muzzle velocity and delivers about 185 pounds of energy at 50 yds. - These violently explode and do the most damage from what I have seen in action.
The .17 HMR 20-grain Gamepoint has a 2,375-fps muzzle velocity and delivers about 193 pounds of energy at the muzzle. - I use these for short range, these are ideal for a bit larger game, stopping around the Coyote mark.
Your best bet within 50 yards is the bottom load. The best past 50 is the top load.
The best overall high damage round is the middle load. It produces a short and wide wound. "Little pink clouds" on small game. I wouldnt try to take game with a 17HMR unless it was past 50 yards, or rabbit sized. Squirrels, chipmunks, and birds will just explode when hit in the body. That being said, you can knock a birds head off at 100 yards with the right setup with relative ease.
