Lets be honest, in a real SD situation, I would take the crappiest ammo over nothing at all. But that is no excuse for not trying out the best ammo. With SD ammo, it is all about expansion. Good ammo like Gold Dots and Winchester Ranger T's and many more will expand to be 150% more than their caliber they were fired from. Some of the basic hollow points will not do the same.
Practice doesn't make perfect, it make permanent.
When I hear a Liberal say "I can speak for gun owners because I own a shotgun" I just want to scream "Well I can speak for vegetarians because I like lettuce on my cheeseburger!"
