One thing you have to consider is available bullets and their construction. The 17s are designed for small varmints and the bullet jackets are quite fragile and expand quickly and violently to "blow up" a thin skinned animal, but their penetration is not very good, and a hit on a bone will end up with a large but very shallow hole in an animal.
This is evident when people use varmint type thin jacketed bullets in a larger calibre hunting rifle for things like Deer. Lots of speed, easy to hit the Deer due to flatter trajectory, but superficial damage on the animal, with the wounded Deer escaping only to die a lingering death. Penetration and internal damage is the key to putting larger animals down. At the same time, using a heavier jacketed game bullet designed for Elk or Moose (180 grain) on a Deer, sometimes will simply poke a hole through the body of the much smaller deer, and will not expand until it has exited the far side of the Deer, because the heavier jacket holds the bullet together longer.
Another example is Bell shooting several hundred Elephants in Africa, using a 6.5 Mannicher-Schoenaur rifle where the 160 grain bullet exited the muzzle at under 2000 fps, but that long bullet penetrated. That 6.5 mm rifle/cartridge combination could really not be thought of as an Elephant gun.
While book figures give a representation of theoretical performance, compared to some other cartridge or calibre, the only way to really tell and compare is experience in the field. Accordion to the theory of Aerodynamics, a Bumble Bee is not supposed to be capable of flight. Tell that to the next one that zaps you with it's stinger.
