Some of the accounts you hear over there during a charge are gut wrenching. But you never know how you will react during a charge until you are actually in that situation.
I was also reading where a client using a double rifle had always trained to place his finger on the front trigger first. That's how he always shot. Trouble is when he was charged he grabbed the back trigger first and when his first shot failed to stop the charge he instinctively was searching for the back trigger, which, of course, he couldn't find as he had already grabbed it. The buff got real close before the PH put it down with his double rifle.
