To answer the thread originator, I don't feel a bit of testosterone when there is a louder bang next to me, I do however feel some machismo if the shooter next to me is more accurate at the same distance. Hey!!!, I would rather have better marksmanship with a 9mm than be a lousy shot with a 10mm ( I am pretty good with both). I am more impressed with skill than I am with the "spraying & praying". One shoots the target, those who merely discharge a gun, are doing just that, spraying lead. Even a broken clock is right twice a day. I would rather be right the first two seconds at 00:00:02
