I see the other guy said this months ago, but it's so important that as a /k/ommando I feel the need to repeat it:
DO NOT SHOOT YOURSELF WITH A .22
People survive self-inflicted headshots ALL THE TIME. Hundreds of people a year. All in all, it's not the best way to go about this, but if you must, use a FULL-POWER (.308/.30-06/7.62.54R/etc) hunting rifle or a shotgun(12 or 20ga) loaded with slugs. That's the only way you can be pretty sure.
