Pretty self-explanatory. What is your preferable brand of defense rounds? I'm currently looking to move to the Winchester Ranger T-Series in .40. I'm not sure what grain I should use though. So, what does everyone else trust their lives with? Forgive me if a thread of this topic has been discussed here in the past. I admit I'm lazy and have not checked to see if one has been started before. I still think it's an interesting subject.
