Welcome wayneesmith999!
As mentioned,, before we can offer any help,, we'd need to know what you plan to hunt.
In general,, .22 LR is used for small game hunting. Squirrels, rabbits, & critters of that size.
9mm ammo is actually more often considered a human self defense caliber.
Yet,, .22 LR has been used to take very large animals,, and the 9mm has failed to stop many a human. But the 9mm has also been used to stop animals most often not considered easily stopped.
Give us details of your inquiry, and we can help guide you into a proper understanding of what you may seek.
