Mr Jones did a great job with a .22.
But sometimes a .22 will do the job and sometimes it will not. Sometimes a .357 Magnum will do the job, and sometimes it will not (see the link to the story of Stacy Lim). But overall, you can expect a .357 Magnum to "deliver the goods" more reliably than the .22.
If you choose a .22, you are trading reliable terminal effectiveness for convenience. If you choose a larger caliber, you are trading convenience for more reliable terminal effectiveness. You get to decide what is most important to you.
