We all know there are hollow points out there that work fairly well and we also know that guns without bullets turn them into very expensive clubs. A solution? Use what you can find and remember the three most important components of stopping power is: bullet placement, bullet placement, and bullet placement. Go with God.

During WWII ball ammo killed a lot of people. While I would prefer to have good hollow points, I would use anything in my supply regardless, hp, flat nose, ball, .45 to .22. As Evan said, placement until the threat is nullified.
