Having said that I'm also comfortable taking a real tight shot if it presents itself based on my skill level. Not talking myself up by any means, some guys just aren't comfortable enough to do that. Being a firearms instructor, rifle instructor, and former entry operator has given me those skills thankfully.
Well, that is what training is supposed to do. If I had an intruder in my house, my mind would be going a gazzilion miles an hour, my heart rate would be about 250 and I would be hyperventilating. So, in other words, I have no clue where my bullet would end up.
If you are trained for that, the entire scene slows down and your mind works better. At least that's the way it's supposed to be.
