That was it. A side shot would be better. Just grip like a close grip bench, bring the bar down to your upper chest, and stop it 6 inches or so off the chest and drive it straight back up. I used to try and roll the bar back an inch and go back up, but I no longer think this is necessary.
You will hit the long head (the lockout head) by doing it the way I have described. Keep the bar in a straight line, stay over upper chest/neck, use pretty heavy weights, keep reps in the 3's and 5's, and for the love of god, use a spotter or do it in a rack. If you are not doing it heavy enough to kill yourself if you make a mistake then you are not going heavy enough.
