I know the feeling. If I could just stop my heart while I shoot like I hold half a breath...

My father, a fine shot, called groups like yours (and a lot of mine) "knowing when the gun was going bang".

It was his theory that the actual firing of the gun should be a surprise, as you squeezed while on target and held while wavering off. Anticipating let off causes twitches in the trigger finger that translate to lateral twitches in the barrel.

Still nice shooting. 5 dead men, or deer...

Not responsible for advice not taken...
