I bought In the Gravest Extreme years ago. I read it every now and then.
You need to have the proper perspective about self defense shootings. Shoot if you have to, but if you can avoid it, do so.
I will not worry about hand loaded ammo being a problem in court. I think hand loaded ammo is slightly less reliable than factory (not by much) and that by itself is reason enough to use factory ammo for self-defense purposes.
I figure if I have to shoot someone, or whack them with a baseball bat, or whatever lethal force I HAVE to use to survive, I hope I can just do it cause it is better to be alive in court than cold on a slab. But if I can avoid it, I will, and I make no apologies for that to those that think it unmanly or that it encourages the bad guys.
His class was scheduled to be taught near here a few years back and I was thinking about taking it, but for some reason it got canceled.
I am completely unaccustomed to ghetto talk. I might well benefit from the application of such aggression just to get used to the idea that the words are harmless. In an encounter where your life is on the line, if some rough language causes you to hesitate, you could end up on the ground slowly bleeding out. Better to get over the shock of the language that might be used in his class.
YMMV.
