My late father always said that the time to squeeze the trigger was when you exhale and your body was relaxed. A chap at work, ex military, said this was wrong and you should take a deep breath, hold it and squeeze?
My question is which is right? or is it a case of providing you use the same method each time thats fine? I feel that the exhaled method is logically a better way as your body does relax - try it.
What do you reckon?
